TL;DR: The double-bundle surgery resulted in significantly fewer graft failures and subsequent revision ACL surgery than the single-b Bundle surgeries during the 5-year follow-up, and no significant group differences were found in the knee scores.
Abstract: Background:Surgical technique is essential in anterior cruciate ligament (ACL) reconstruction.Purpose:This randomized 5-year study tested the hypothesis that double-bundle ACL reconstruction with hamstring autografts and aperture screw fixation has fewer graft ruptures and rates of osteoarthritis (OA) and better stability than single-bundle reconstruction.Study Design:Randomized controlled trial; Level of evidence, 1.Methods:Ninety patients were randomized: double-bundle ACL reconstruction with bioabsorbable screw fixation (DB group; n = 30), single-bundle ACL reconstruction with bioabsorbable screw fixation (SBB group; n = 30), and single-bundle ACL reconstruction with metallic screw fixation (SBM group; n = 30). The following evaluation methods were used: clinical examination, KT-1000 arthrometer measurement, and International Knee Documentation Committee (IKDC) and Lysholm knee scores. Additionally, radiographic evaluation was made by a musculoskeletal radiologist who was unaware of the patients’ clini...

TL;DR: An increase in the incidence of the surgical treatment of proximal humeral fractures was seen in Finland in 1987–2009 and Fracture plating became increasingly popular since 2002.
Abstract: Proximal humeral fractures are common osteoporotic fractures. Most proximal humeral fractures are treated non-surgically, although surgical treatment has gained popularity. The purpose of this study was to determine changes in the surgical treatment of proximal humeral fractures in Finland between 1987 and 2009. The study covered the entire adult (>19 y) population in Finland over the 23-year period from 1st of January 1987 to 31st of December 2009. We assessed the number and incidence of surgically treated proximal humeral fractures in each year of observation and recorded the type of surgery used. The cohort study was based on data from Finnish National Hospital Discharge Register. During the 23-year study period, a total of 10,560 surgical operations for proximal humeral fractures were performed in Finland. The overall incidence of these operations nearly quadrupled between 1987 and 2009. After the year 2002, the number of patients treated with plating increased. An increase in the incidence of the surgical treatment of proximal humeral fractures was seen in Finland in 1987–2009. Fracture plating became increasingly popular since 2002. As optimal indications for each surgical treatment modality in the treatment of proximal humeral fractures are not known, critical evaluation of each individual treatment method is needed.

TL;DR: A marked increase in the surgical treatment of humeral-shaft fractures was seen in Finland in 1987-2009, with a clear shift towards plating.
Abstract: Summary Introduction Humeral-shaft fractures are not uncommon osteoporotic fractures. While most of the humeral-shaft fractures can be treated conservatively, some need surgical treatment. The purpose of this study was to assess the trends of the surgical treatment of humeral-shaft fractures. The study determined whether surgical treatment of humeral-shaft fractures has changed in Finland between 1987 and 2009. We assessed the number and incidence of surgically treated humeral-shaft fractures in each year and recorded the type of surgery used. Patients and methods The study covered the entire adult (>18 years) population in Finland over the 23-year period from 1 January 1987 to 31 December 2009. Data on surgically treated humeral-shaft fractures were obtained from the nationwide National Hospital Discharge Registry. Results During the 23-year study period, a total of 4469 surgical operations of the humeral shaft were performed in Finland. The male patients were markedly younger (49 years) than their female counterparts (63 years). The incidence of surgical treatment nearly doubled in men and over tripled in women. Between 1987 and 2009, there occurred a clear shift towards plating in the surgical treatment of humeral-shaft fractures. Conclusions A marked increase in the surgical treatment of humeral-shaft fractures was seen in Finland in 1987–2009. Fracture plating increased during the first decade of the millennium. Since high-quality evidence for treatment of humeral-shaft fractures is absent, critical evaluation of the chosen treatment options is needed.

TL;DR: A 2-year randomized double-blind placebo-controlled vitamin D and open exercise trial of 409 home-dwelling women 70 to 80 years of age to provide evidence on the effectiveness of exercise and vitamin D for falls reduction.
Abstract: Falls are the leading cause of unintentional injury and injury-related death among older people. In addition to physical activity, vitamin D also may affect balance and neuromuscular function. Low serum 25-hydroksivitamin D level increases the risk of bone loss, falls and fractures. Thus, an appropriate exercise program and sufficient vitamin D intake may significantly improve not only functional balance, but also balance confidence. Balance represents a complex motor skill determined by reaction time, muscle strength, and speed and coordination of movement. A 2-year randomized double-blind placebo-controlled vitamin D and open exercise trial of 409 home-dwelling women 70 to 80 years of age comprising four study arms: 1) exercise + vitamin D (800 IU/d), 2) exercise + placebo, 3) no exercise + vitamin D (800 IU/d), 4) no exercise + placebo. In addition to monthly fall diaries, general health status, life style, bone health, physical functioning, and vitamin D metabolism will be assessed. The primary outcomes are the rate of falls and fall-related injuries. Secondary outcomes include changes in neuromuscular functioning (e.g. body balance, muscle strength), ADL- and mobility functions, bone density and structure, cardiovascular risk factors, quality of life and fear of falling. The successful completion of this trial will provide evidence on the effectiveness of exercise and vitamin D for falls reduction. ClinicalTrial.gov -register (

TL;DR: The exercise intervention showed rather limited effects on HRQoL and FoF among relatively high-functioning older women, and this modest result may be partly because of insufficient responsiveness of the assessment instruments used.
Abstract: This randomized, controlled trial evaluated the effects of exercise on health-related quality of life (HRQoL) and fear of falling (FoF) among 149 home-dwelling older women. The 12-mo exercise program was intended to reduce the risk of falls and fractures. HRQoL was assessed by the RAND-36 Survey, and FoF, with a visual analog scale, at baseline, 12 mo, and 24 mo. On all RAND-36 scales, the scores indicated better health and well-being. The exercise had hardly any effect on HRQoL; only the general health score improved slightly compared with controls at 12 mo (p = .019), but this gain was lost at 24 mo. FoF decreased in both groups during the intervention with no between-groups difference at 12 or 24 mo. In conclusion, despite beneficial physiological changes, the exercise intervention showed rather limited effects on HRQoL and FoF among relatively high-functioning older women. This modest result may be partly because of insufficient responsiveness of the assessment instruments used.

TL;DR: The 18-month high-impact exercise intervention strengthened the femoral neck in premenopausal women by enhancing its structural properties; however, this benefit was not maintained at 3.5 year follow-up and the exercise benefits on physical performance continued to be maintained 3.
Abstract: Purpose: This study evaluated the training effects of an 18-month exercise intervention and subsequent 3.5-year follow-up on femoral neck structure in premenopausal women. Methods: Of 98 women who participated in this randomized controlled study, 84 (39 trainees and 45 controls) completed the 18-month intervention. At both 18 months and 3.5 years, dual-energy X-ray absorptiometry data on 22 trainees and 22 control participants (ages 35–45 y) were available for hip structural analysis. The section modulus (Z), cross-sectional area (CSA), and subperiosteal width at the femoral neck were analyzed. Lower-leg explosive power and estimated maximal oxygen uptake (Vo2max) were assessed by vertical countermovement jump and standardized 2 km walking test, respectively. Progressive supervised high-impact exercises were done three times per week for 18 months. Results: Significant between-group differences in favour of trainees were observed after the 18-month intervention in Z (3.2%, p=0.047) and CSA (2.8%,...
