Osteoarthritis revisited: a contemporary review of aetiology

Abstract: Osteoarthritis is among the most common pathological conditions in skeletal collections and is the most frequent musculoskeletal disorder in contemporary populations. Jurmain (1991) has previously published in this journal a brief review of skeletal perspectives on osteoarthritis. Subsequent studies by osteologists and medical researchers have added considerably to understanding of the aetiology and patterning of osteoarthritis. Thus, it is timely to present an updated review that expands and supports conclusions discussed in the earlier review. In short, osteoarthritis aetiology is multifactorial, with age being the main influence on the onset and severity of osteoarthritis. Genetic influences also play a large role in the severity of osteoarthritis, especially in the lower limbs. Weight, although playing a significant role for modern populations, seems to have had very minimal effects on prehistoric populations. Sex differences may often be a consequence of hormones, body size and anatomy, rather than activity related. Finally, intense activity starting at a young age still may influence osteoarthritis, especially in the upper limbs. Future directions discussed include within-body comparisons, animal studies, and examining patterns in large populations. Copyright © 2007 John Wiley & Sons, Ltd.

Dental trauma and antemortem tooth loss in prehistoric Canary Islanders: prevalence and contributing factors

Abstract: Differential diagnosis of the aetiology of antemortem tooth loss (AMTL) may yield important insights regarding patterns of behaviour in prehistoric peoples. Variation in the consistency of food due to its toughness and to food preparation methods is a primary factor in AMTL, with dental wear or caries a significant precipitating factor. Nutritional deficiency diseases, dental ablation for aesthetic or ritual reasons, and traumatic injury may also contribute to the frequency of AMTL. Systematic observations of dental pathology were conducted on crania and mandibles at the Museo Arqueologico de Tenerife. Observations of AMTL revealed elevated frequencies and remarkable aspects of tooth crown evulsion. This report documents a 9.0% overall rate of AMTL among the ancient inhabitants of the island of Tenerife in the Canary Archipelago. Sex-specific tooth count rates of AMTL are 9.8% for males and 8.1% for females, and maxillary AMTL rates (10.2%) are higher than mandibular tooth loss rates (7.8%) Dental trauma makes a small but noticeable contribution to tooth loss among the Guanches, especially among males. In several cases of tooth crown evulsion, the dental root was retained in the alveolus, without periapical infection, and alveolar bone was in the initial stages of sequestering the dental root. In Tenerife, antemortem loss of maxillary anterior teeth is consistent with two potential causal factors: (a) accidental falls while traversing volcanic terrain; and (b) interpersonal combat, including traditional wrestling, stick-fighting and ritual combat. Steep-walled valleys (barrancos) and lava fields (malpais) required agile locomotion and occasional vaulting with the aid of a wooden staff. Accidental falls involving facial injury may have contributed to AMTL. Traditional conflict resolution involved competitive wrestling (lucha canaria), stick-fighting (juego del palo), and ritualised contests involving manual combat. These activities made a small but recognisable impact on anterior dental trauma and tooth loss. Inter-personal behaviours of such intensity leave their mark on skeletal and dental remains, thereby providing insight into the lives and cultural traditions of the ancient Guanches.

Age-related variation in isotopic indicators of diet at medieval Kulubnarti, Sudanese Nubia

Abstract: This study compares trends in dietary composition in two large cemetery populations from the site of Kulubnarti (AD 550–800) in Sudanese Nubia. Bone collagen and bone apatite carbonate were analysed to characterise stable carbon, nitrogen and oxygen isotopes. Previous research on these cemeteries has suggested marked differences in nutritional status and health between the populations. Contrary to expectations, there were no significant relationships between any isotopic indicators related to sex or cemetery of burial, suggesting no isotopically-measurable differences in diet. However, collagen δ13C and δ15N were significantly related to age, suggesting age-related differences in protein intake or other factors. Weaning trends are gradual and variable, with the range in δ15N values exceeding 4‰ among infants/young children (0–3 yrs) and standard deviations exceeding 1‰ in collagen δ13C and δ15N for both infants/young children and subadults (4–17 yrs). This suggests varied weaning strategies among both populations and variable diets prior to adulthood. Also observed was a distinct range of isotopic carbon and nitrogen values among individuals classified as subadults (4–17 yrs), who are depleted in collagen δ13C and δ15N relative to adults. However, both infants/young children and subadults are slightly enriched in δ18O relative to adults, which suggests the presence of non-local individuals or age-related variation in water sources. While most isotopic studies of age-related dietary trends have focused on reconstructing the weaning process, this study presents findings that indicate tripartite isotopic trends distinguishing infancy, subadulthood and adulthood as separate dietary categories. Broad similarities are evident between the results presented here and those from several earlier studies of smaller populations and to nutritional studies of modern communities. These findings suggest that further research into health disparities at Kulubnarti should focus on non-dietary causal factors, and more generally, that greater attention should be paid to subadulthood in palaeodiet studies.

Thalassemia: macroscopic and radiological study of a case

Abstract: Differentiation of the genetic and the acquired anaemias, particularly in areas of the world where they may co-exist, has been a challenge for palaeopathologists for over 100 years. In this paper we present macroscopic and radiographic skeletal lesions that are associated with the thalassemias in a 14-year-old girl from a modern reference collection of the University of Athens. This individual is of known sex, age, cause of death, place and dates of birth and death. The case is examined in terms of epidemiology, growth, distribution and severity of lesions and differential diagnosis. The entire skeleton is affected by marrow hyperplasia: lesions of the axial skeleton are extreme, and the appendicular skeleton is severely affected as well. The odontofacial manifestations that are diagnostic of thalassemia and differentiate it from other anaemias are present and include: maxillary and mandibular hyperplasia, reduced sinuses, displacement of maxillary dental structures, overbite, and generalised osteopenia. The development of extreme bone lesions and the ‘advanced’ age-at-death of this individual is explained as either the result of thalassemia major under a low transfusion regimen that was the norm during her lifetime, or to a form of thalassemia intermedia that allows survival to later life at the expense of gross skeletal alterations. The present status of skeletal studies in Greece does not support the identification of a genetic anaemia in past populations. The potential contribution of the current analysis in differentiating the anaemias in antiquity is evaluated. Copyright © 2006 John Wiley & Sons, Ltd.

Molecular history of tuberculosis from ancient mummies and skeletons

Abstract: The origin and evolution of the infectious disease tuberculosis (TB) and its pathogens is still not fully understood. An important effort for a better understanding of the underlying mechanisms of TB evolution lies within the investigation of skeletal and mummified material dating back several thousand of years. In this work, molecular data from mummified and skeletal material from different time periods of the Old World are compared, and the current status of ancient mycobacterial DNA analysis in ancient human remains is discussed, with particular reference to the genetic evolution of human TB. The molecular analysis of material from southern Germany (1400–1800 AD), Hungary (600–1700 AD) and Egypt (3500–500 BC) revealed high frequencies of TB in all time periods. In several individuals from ancient Egypt the mycobacterial DNA could be further characterised by spoligotyping. Thereby, evidence for ancestral M. tuberculosis strains was found in the pre- to early dynastic material from Abydos (3500–2650 BC), while typical M. africanum signatures were detected in the Middle Kingdom tomb in Thebes-West (2050–1650 BC). Samples from the New Kingdom to Late Period tombs (1500–500 BC) were characterised as modern M. tuberculosis strains. In concordance with other studies on ancient skeletal and mummified samples, no evidence for the presence of M. bovis was found. These results contradict the theory that M. tuberculosis evolved from M. bovis during domestication, but supports the new scenario that M. tuberculosis probably derived from an ancestral progenitor strain.

Residential mobility and resource use in the Chiribaya polity of southern Peru: strontium isotope analysis of archaeological tooth enamel and bone

Abstract: The Chiribaya were a complex polity during the Andean Late Intermediate Period (c. AD 1000–1300) in the Ilo and Moquegua Valleys of southern Peru. Recent research has demonstrated that the Chiribaya polity was a senorio, a confederacy of economically specialised parcialidades. Here we test hypotheses regarding the movement of individuals and resources among the Chiribaya-affiliated sites of Chiribaya Alta, Chiribaya Baja, San Geronimo and El Yaral, as well as from outside of the Ilo and Moquegua Valleys. Although archaeological human enamel and bone strontium isotope ratios from Chiribaya Baja and San Geronimo cluster closely, there is a wider variety of strontium isotope ratios observed at Chiribaya Alta and El Yaral. This indicates that individuals buried in cemeteries at these sites had access to a wider variety of resources, and probably moved between different geological zones throughout their lifetimes.

Histological study of compact bone tissue in some mammals: a method for species determination

Abstract: The purpose of this investigation was to study compact bone tissue microstructure of some mammals in terms of qualitative and quantitative characteristics, with an emphasis on finding an adequate identification key. Altogether, 36 femora of adult pigs, cows, sheep and rabbits were analysed. The qualitative characteristics were examined according to the classification systems of Enlow & Brown (1956) and Ricqles et al. (1991) in anterior, posterior, medial and lateral views of thin sections. The quantitative characteristics were assessed using the specific software Scion Image (Scion Corporation, US). We measured area, perimeter, and minimum and maximum diameter of the Haversian canals, the secondary osteons and the vascular canals of primary osteons. The observed data were first used to evaluate inter- and intra-species diversity. After that a discriminant function analysis was used for species determination. According to our results the basic structural pattern of the bone tissue was primary vascular plexiform in pigs, cows and sheep. We found dense Haversian bone tissue in all species. In addition, non-vascular bone tissue was identified in cows and/or primary vascular longitudinal tissue in rabbits. Many resorption lacunae were found between secondary osteons in pigs. The irregular Haversian bone tissue was localised at the periosteal and endosteal borders in sheep. Classification functions for all investigated species gave a correct classification in 73.83% of cases. The most discriminating variables for the compact bone tissue appeared to be perimeter and minimum diameter of primary osteon's vascular canals. The percentage value can be increased by integrating conclusions from the qualitative analysis. Copyright © 2006 John Wiley & Sons, Ltd.

Hunter-gatherer Use of Small Animal Food Resources: Coprolite Evidence

Abstract: Faunal remains are commonly found in coprolites and provide direct evidence of animal consumption. An evaluation of hunter-gatherer coprolites from the Southwest United States shows that animal bone in coprolites can be used to assess patterns of hunting, food preparation, and general importance of small animals in diet. This is demonstrated by a comparison of faunal assemblages between two hunter-gatherer sites with respect to small animal hunting strat- egies. The sites are Dust Devil Cave on the Colorado Plateau, an Archaic winter habitation, and Hinds Cave, a warm season Archaic habitation in the lower Pecos of Texas. The results indicate that small animal hunting varied region- ally and seasonally.

The ancient inhabitants of Jebel Moya Redux: Measures of Population Affinity based on dental morphology

Abstract: This paper reexamines some of the methods and craniometric findings in the classic volume The Ancient Inhabitants of Jebel Moya (Sudan) (1955) by Mukherjee, Rao & Trevor, in light of recent archaeological data and relative to a new dental morphological study. Archaeological evidence characterises these inhabitants as having been heavily influenced by outside sources; yet they managed to establish and maintain their own distinctive culture as seen in the site features and surviving artefact collections. The dental study, modelled after the original craniometric-based investigation and using the same or similar comparative samples, detected complementary indications of outside biological influence. In the study, up to 36 dental traits were recorded in a total of 19 African samples. The most influential traits in driving inter-sample variation were then identified, and phenetic affinities were calculated using the Mahalanobis D2 statistic for non-metric traits. If phenetic similarity provides an estimate of genetic relatedness, these affinities, like the original craniometric findings, suggest that the Jebel Moyans exhibited a mosaic of features that are reminiscent of, yet distinct from, both sub-Saharan and North African peoples. Together, these different lines of evidence correspond to portray the Jebel Moya populace as a uniform, although distinct, biocultural amalgam. Copyright © 2006 John Wiley & Sons, Ltd.

Lifestyle, occupation, and whole bone morphology of the pre‐Hispanic Maya coastal population from Xcambó, Yucatan, Mexico

Abstract: The present bioarchaeological study examines the external diaphyseal geometric properties of humeri, radii, femora and tibiae of the Classic period skeletal population of Xcambo, Yucatan, Mexico. The diaphysial proportions are evaluated using a biomechanical approach together with data from the material context and other osteological information. Our intent is to provide new answers to questions concerning lifestyle, domestic labour division and subsistence strategies of this coastal Maya settlement that was inhabited from the Late and Terminal Preclassic (300 BC–350 AD) to the Postclassic Period (900–1500 AD). Our results provide evidence for a marked sexual division of labour when compared with values from contemporaneous inland populations. The overall male and female loading patterns differ remarkably in terms of form and in bilateral comparison. A high directional asymmetry in the upper limbs is evident among males, a condition related to maritime transportation and trading activities. On the other hand, female upper limbs are characterized by very low side differences. Forces on the arms of women were probably dominated by food processing, in particular the grinding of grains or seeds. In the lower limbs, males show significantly higher anteroposterior bending strengths, which can be explained by greater engagement in transportation tasks and carrying heavy loads. In the course of the Classic period (350–900 AD), diachronic changes affect the male sample only, which suggests a shift of occupational pattern and physical demands. This shift, in turn, reflects Xcambo's changing role as the centre of a densifying settlement area and its place in the trading activities of northern Yucatan. Other topics of discussion relate to general regional trends and local prehispanic subsistence strategies. Our conclusions emphasize the value of geometric long bone analysis in the reconstruction of activity patterns and lifestyles in ancient coastal settlements. Copyright © 2007 John Wiley & Sons, Ltd.

Pathogenesis of apical periodontal cysts: guidelines for diagnosis in palaeopathology

Abstract: Apical periodontal cysts are benign lesions developing in relation to the apices of non-vital teeth due to inflammatory response from the infective pulp. These are epithelium-lined bony cavities containing fluid. Despite being widely reported in medical/dental literature, this common condition is poorly diagnosed and documented in the archaeological literature. We aim to clarify the correct terminology, demonstrate bony manifestations at different stages of pathogenesis of chronic periapical dental lesions into granuloma and apical periodontal cysts, and to describe diagnostic criteria which would provide practical guidelines for the diagnosis of these conditions. Three identified skulls from the International Exchange Collection, housed in the Anthropological Museum at the University of Coimbra, are used to identify the progression of this condition from a small periapical granuloma to a large apical periodontal cyst with expansion of alveolar and facial bones. The pathogenesis of this condition is described, together with its surgical management in the early 20th century in Portugal, which is the period in which these individuals lived. Confusion resulting from the different terminologies can be avoided if the term periapical granuloma is used to define apical bony lesions smaller than 3 mm at their maximum intra-bony diameter, and the term apical periodontal cysts for the larger lesions. We recommend that these terminologies and parameters be used as a standard in future studies. This will make inter-observer and inter-population comparisons more accurate.

Infectious diseases and eating habits at Herculaneum (1st century AD, southern Italy)

Abstract: This paper shows that many food remains excavated from Herculaneum were microbiologically contaminated, and that the Romans probably had continuous exposure to gastrointestinal diseases. However, palaeopathological analysis of skeletal remains from Herculaneum shows a low prevalence of non-specific bone inflammation. Pomegranates and figs, consumed by the population, were mainly dried and invariably contaminated by Streptomyces, a bacterium that produces natural tetracycline, an antibiotic. Histological analysis of the human remains demonstrates fluorescence typical of this substance. The tetracycline-labelled human remains show that the Roman inhabitants of Herculaneum ate food contaminated by Streptomyces, and this may explain the rarity of inflammatory bone diseases at the site due to non-specific infection in the living population. This interpretation fits with therapeutic indications suggested by Roman physicians that preserved fruits were used to cure some inflammatory diseases. Copyright © 2007 John Wiley & Sons, Ltd.

Craniofacial trauma in the Prehispanic Canary Islands

Abstract: The current project is a study of craniofacial trauma in a large sample (n = 896) of Prehispanic Canary Islanders (PCIs). The possible causes and social implications of the trauma found are considered, with reference to archaeological and historical data. Variables include the island, period and ecology, the sex and age of the individuals, the distribution of lesions across the skull (by side and by individual bone) and ante-mortem tooth loss. The results show a fairly high trauma rate (16%), a low prevalence of peri-mortem trauma (3.8% of all lesions), higher prevalence of trauma in males than in females (25% vs. 13% of all individuals), more cranial than facial lesions (8.9% vs. 3.5% of all elements) and more lesions on the left side of the skull (6.7% vs. 4.5% of all elements) which suggests that the lesions were sustained through intentional rather than accidental agency. There was no correspondence between trauma prevalence and ecology. The archaeological and historical data support the assertion that the lesions may be the result of skirmishing between groups, using weapons such as slingshots, stones and staves. The presence of edged-weapon lesions on some individuals suggests that these may have been the victims of contact-period European groups. Copyright © 2007 John Wiley & Sons, Ltd.

Metastatic carcinoma: Palaeopathology and differential diagnosis

Abstract: A 62 year-old contemporary white female diagnosed with metastatic carcinoma of the breast was examined after skeletonisation. She never received chemical, hormonal or radiation therapy. Because of the confirmed clinical diagnosis, lack of medicinal intervention, and quality of bone preservation, this specimen provides a comparative standard for metastatic carcinoma and differential diagnosis of idiopathic dry bone pathology. We detail gross and radiographic bone response to this disease and differentially diagnose the skeleton against Langerhans cell histiocytosis and multiple myeloma, conditions capable of modifying bone in characteristic patterns that may mimic metastatic carcinoma.

The Middle Byzantine menu: palaeodietary information from isotopic analysis of humans and fauna from Kastella, Crete

Abstract: We report here on the measurements of carbon and nitrogen stable isotopes of bone collagen from the Middle Byzantine site of Kastella, in the city of Heraklion, on the island of Crete, Greece. The data derived from the analysis suggest a diet based primarily on terrestrial, C3 protein, probably from animal sources, with the inclusion of some marine protein. The adult diet at this site is relatively uniform, with no detectable differences between average isotopic values for males and females. We also found that bone collagen 15N values for a small number of juveniles decreased to adult levels after the age of two years, indicating that weaning occurred at or before this age.

Ossification of the interosseous ligaments between the metapodials in horses: a new recording methodology and preliminary study

Abstract: This article presents a methodology for recording and quantifying the ossification of the interosseous ligaments between the metapodials in horses, including a scoring system for defining stages in the development of this lesion. The method is applied to a sample of ten Przewalski's horse skeletons from the National Museum, Prague. This case study demonstrates the nature of this lesion in a sample of unworked animals and presents a preliminary sample for comparison with archaeological assemblages. The results show that the condition can occur in animals that are not worked. They also indicate that age is an important factor in the development of the lesion. The expression of the pathology in this sample appears to be linked to how the weight of the animal acts through the legs, in that it occurs earliest, and is generally more advanced, in the areas that support a greater burden.

Earliest evidence of spinal tuberculosis from the Aneolithic Yayoi period in Japan

Abstract: Tuberculosis has existed from early prehistoric days to modern times. The main causative agents of tuberculosis worldwide are Mycobacterium tuberculosis (M. tuberculosis) and M. bovis, along with M. africanum, M. cenettii and M. microti; these species make up the ‘M. tuberculosis complex’. This worldwide infection has been of special interest to palaeopathologists due to its characteristic bone lesions as well as its great antiquity. Historically, tuberculosis has been recognised in Japan for more than a thousand years. However, the origin and early prevalence of tuberculosis remain unknown. In the present study, we present the earliest evidence of skeletal tuberculosis found in the Aneolithic Yayoi period in Japan (ca. 300 BC to AD 300). The skeletal remains showing typical pathological changes of spinal tuberculosis were dated to between 454 BC and AD 124 by dendrochronological methods using coburied arrow-shield board and house columns made of Japanese cedar. We discuss the early prevalence of this infectious disease and its influence on the population history of the Japanese from prehistoric to Aneolithic times. Copyright © 2006 John Wiley & Sons, Ltd.

Estimation of adult skeletal age‐at‐death: statistical assumptions and applications

Abstract: We examine the statistical assumptions underlying different techniques of estimating the age-at-death of a skeleton from one or more age indicators. The preferred method depends on which property of the distribution of the data in the reference sample is preserved in the skeleton to be aged. In cases where the conditional distribution of age given indicator is preserved, we provide look-up tables giving essentially unbiased age estimates and prediction intervals, using a large reference sample and the auricular surface and pubic symphysis age indicators. Where this assumption is violated, but the conditional distribution of indicator given age is preserved, we find that an alternative model which attempts to capture the biological process of development of an individual has some attractive features, which may make it suitable for further study.

Identifying artificially deformed crania

Abstract: In this paper we report on a new discriminant function for the identification of artificially deformed crania. Development of the function, based on a sample of deformed and undeformed crania from the Philippines, required visual classification of the sample into deformed and undeformed groups. Working from the observation that deformed crania display flattened frontal and occipital regions, the sample was seriated based on degree of flattening; classification was based on the results of this seriation. The discriminant function, calculated using curvature indices, required only six simple measurements: arc and chord measurements for the frontal (glabella to bregma), parietals (bregma to lambda) and occipital (lambda to opisthion). The function was designed to be conservative, in that a deformed cranium may be classified as undeformed, but the opposite should not occur. Our function classified the undeformed crania with 100% accuracy and deformed crania with 76.9% accuracy, for a total of 91.9% agreement with visual classification. In order to evaluate whether the function is applicable for samples from outside the Philippines, a double blind test was conducted with a large sample of deformed and undeformed crania from a broad geographical and temporal range. For this sample, the function agreed with visual classification in 89.7% of cases; 98.8% of undeformed crania were correctly classified, while deformed crania were identified with 73.7% accuracy. These results demonstrate the utility of the new discriminant function for the classification of artificially deformed crania from diverse contexts. Copyright © 2007 John Wiley & Sons, Ltd.

Childhood trauma in several populations from the Iberian Peninsula

Abstract: A study was conducted on a collection of 123 juvenile skeletons from various sites dating to the Bronze Age (Argar culture) and from the medieval cemeteries of La Torrecilla, Villanueva de Soportilla and San Baudelio, all in the Iberian Peninsula No cranial trauma was observed However, four postcranial fractures were found, including three from Castellon Alto, a typical Argaric village of some urban complexity built on steep terraces in high and rugged terrain The combination of a hazardous environment and a climate that encourages outdoor play may explain the relatively high frequency of childhood trauma in the burials from the Argar culture Copyright © 2006 John Wiley & Sons, Ltd

Wild or domestic? Biometric variation in the cat Felis silvestris Schreber

Abstract: Investigation of modern biometric data indicates that it may be possible to distinguish wildcats from house cats in many instances. Applying the log-ratio (log-difference) technique to archaeological samples from medieval northern Europe, and to mixed samples of wildcats and house cats, shows that the differentiation may not always be clear, and the possibility that some samples include hybrids is discussed. The technique is applied to samples from the Orkney Islands to demonstrate that single wildcat specimens can be identified in small samples. Copyright (C) 2007 John Wiley & Sons, Ltd.

Scapular development from the neonatal period to skeletal maturity: A preliminary study

Abstract: An understanding of the basic growth rates and patterns of development for each element of the human skeleton is important for a thorough understanding and interpretation of data in all areas of skeletal research. Yet surprisingly little is known about the detailed ontogenetic development of many bones, including the scapula. With the intention of describing the changes that accompany postnatal ontogeny in the scapula and algorithms to predict sub-adult age at death, this communication examines the development of the scapula through nine measurements (3 from the glenoidal area, 4 from the body and 2 related to the spinous process) by polynomial regression. Data were collected from 31 of the individuals that comprise the Scheuer Collection, which is housed at the University of Dundee (Scotland). Four of the derived mathematical curves (scapular length, infra- and suprascapular height and spine length) displayed linear growth, whilst three (maximum length of the glenoid mass, acromial width and scapular width) were best expressed by a second-degree polynomial and two (maximum and middle diameter of the glenoidal surface) by a third-degree polynomial. All single measurements proved useful in the prediction of age at death, although derived indices proved to be of limited value. In particular, scapular width, suprascapular height and acromial width showed reliable levels of age prediction until late adolescent years. Copyright © 2007 John Wiley & Sons, Ltd.

Variation in the development of postcranial robusticity: an example from Çatalhöyük, Turkey

Abstract: While the study of variation in adult postcranial robusticity has a long history, few analyses have examined the acquisition of postcranial robusticity within an ontogenetic context. This research evaluates differences in the ontogenetic trajectories of immature femora from three samples, in order to assess the point at which differences in levels of adult postcranial robusticity arise during development. Femoral midshaft cross-sectional properties were compared between three diverse samples: Neolithic agriculturalists from Catalhoyuk, Turkey (n = 42); Byzantine agriculturalists from Catalhoyuk, Turkey (n = 24); and urban Americans from the Denver Growth Study (n = 151). While the two adult samples from Catalhoyuk do not differ statistically, both Neolithic and Byzantine adults have relatively larger cortical and total areas than the American urban adults, and these differences are clearly established by the age of six. In addition, by the age of three, individuals from the Denver Growth Study have already attained a greater percentage of their adult length, total area, and cortical area relative to those in both the Neolithic and Byzantine samples. These results indicate that the differing levels of postcranial robusticity characterising adult populations appear relatively early during development, and that populations vary in the rate and pattern through which adult levels of postcranial robusticity are achieved.

Bone mineral densities in the prehistoric, Viking‐Age and medieval populations of Norway

Abstract: Osteoporosis is a prevalent condition in Norway, as evidenced by the fact that this country has the highest reported incidences of hip and distal forearm fractures. Because recent studies suggest a higher bone density in rural populations compared with urban ones, increased physical activity is believed to be an important factor in reducing fracture incidence. In the present investigation, 185 femoral necks from the Schreiner Collection in Oslo were measured by means of a bone-mass scanner. The bones, anthropological specimens ranging from the Stone Age to the Middle Ages, were separated into three groups: prehistoric (n = 36), Viking Age (n = 38) and medieval (n = 111). The medieval group was further separated into urban, rural and monastic populations. The examination showed that: (a) there was no significant difference at a 5% level in average bone mineral density (BMD) between the male and female material; (b) there was no significant difference in average BMD among the prehistoric, Viking Age, and medieval periods (P = 0.151); (c) there was no significant difference in average BMD between the rural and urban medieval material; (d) there was a significant difference in average BMD only between the monastic and the rural medieval material; (e) only the medieval material showed a significantly higher average BMD than that of today (P = 0.001). These findings may indicate that factors in addition to physical activity are important for normal BMD maintenance. Copyright © 2006 John Wiley & Sons, Ltd.

Infancy and childhood in the pre‐Columbian North American Southwest–first results of the palaeopathological investigation of the skeletons from the Grasshopper Pueblo, Arizona

Abstract: Infant and child skeletons (n = 369) from the pre-Columbian Grasshopper Pueblo site in east-central Arizona (US) dating from the 14th century AD were examined macroscopically and with low-power microscopy. They were studied as a representative example of a typical Mogollon community with respect to frequencies of deficiency and inflammatory diseases. First results revealed very poor living conditions, which are characteristic for this time period in the North American Southwest because of lack of food due to climatic and political changes. Thus, non-specific stress indicators were frequently observed. In the group of deficiency diseases, anaemia was found in more than 50% of individuals, and in the group of inflammatory diseases, meningeal irritations were diagnosed in more than 70%.

Skeletal evidence for hyperparathyroidism in a 19th century child with rickets

Abstract: The skeletal remains of a child aged 2.5–3.5 years, recovered during archaeological excavations at the churchyard of St Martin's Church, Birmingham, UK, were examined using gross observation, radiography and scanning electron microscopy. Lesions suggestive of the presence of rickets and of secondary hyperparathyroidism were found. This appears to be a first report of secondary hyperparathyroidism in response to rickets in a palaeopathological specimen. The potential of microscopic examination of bone for interpreting disease processes is emphasised. Copyright © 2006 John Wiley & Sons, Ltd.

Sexing cattle horn‐cores: problems and progress

Abstract: It has long been recognised that cattle horn-cores are sexually dimorphic, and many methods have been developed using archaeological material for differentiating between specimens belonging to cows, bulls and oxen. Whilst these techniques have been adopted widely by zooarchaeologists, in particular those studying medieval and post-medieval tannery and horn-working assemblages, they are highly subjective and their reliability has never been tested using material from cattle of known sex. This paper seeks to redress the balance. It presents the results of a study of 19th and 20th century cattle horn-cores, from animals of known age, sex and breed, which were examined and measured in order to test the validity of traditional horn-core sexing techniques. Previously claimed traits of sexual variation are here refuted, and a new metrical threshold for separating the males and females of ‘medium-horned’ and ‘long-horned’ types are presented.

Klippel‐Feil syndrome in an Early Hungarian Period juvenile skeleton from Austria

Abstract: The excellently preserved skeleton of a juvenile from the Early Hungarian Period (10th century AD), recently excavated in Gnadendorf (Lower Austria), displays typical symptoms of Type II congenital ‘Klippel-Feil syndrome’ (KFS): fused cervical vertebrae 2 and 3, and fused thoracic vertebrae 2 and 3. Other features observed in this skeleton clinically reported for KFS include a basilar impression and a spina bifida occulta. The bilateral symmetrical hypoplasia of the basilar part of the occipital bone is probably also linked to this syndrome, as well as the constricted external acoustic meati, which almost certainly led to hearing impairment. A cranial lesion and its possible consequences are discussed in the context of the specific KFS alterations. Copyright © 2006 John Wiley & Sons, Ltd.

Trepanation in the Chachapoya region of northern Perú

Abstract: This paper discusses trepanation frequency data from the Chachapoya region of the northern highlands of Peru. New data from three skeletal samples are presented: Kuelap, Laguna Huayabamba, and Los Pinchudos, as well as isolated crania housed at the Chachapoya Museo Instituto Nacional de Cultura. The vast majority of the trepanations are circular in shape, except for one individual exhibiting as many as three roughly square trepanations. Evidence for healing is prevalent, with examples of both associated periosteal reaction of nearby outer table bone, as well as for healing of the insult itself. Only one case demonstrates a clear association between a traumatic injury and a trepanation event. The purpose or function of the remaining cases of trepanation, however, remains elusive.

Lysis at the anterior vertebral body margin: evidence for brucellar spondylitis?

Abstract: Recently, palaeopathologists have begun to diagnose brucellosis in skeletal remains from minor lytic lesions located on the anterior margins of one or some few vertebral bodies, taking these lesions to represent brucellar epiphysitis. However, review of the literature indicates that these lesions have been sporadically noted for some time by palaeopathologists and various different interpretations have been placed upon them. In view of this, a study of these vertebral marginal lesions (VML) was undertaken in a large series of archaeological skeletons from England, with the aim of characterising their morphology and frequency and shedding light upon their causes. In the study material, VML were found only in the lumbar spine, where they occurred with a prevalence of approximately 4%. It was argued that VML are consistent with two principal alternative diagnoses: brucellosis and traumatic anterior disc herniation. Differentiating these possibilities for the VML in the study material was difficult, but the balance of the evidence seemed to favour traumatic anterior disc herniation as the more likely cause. It is concluded that VML should not be used to identify the presence of brucellosis in skeletal remains unless there is further evidence, in the form of additional skeletal lesions or biomolecular evidence for residual brucella bacterial DNA, to support such a diagnosis.
