COVID-19: Initial experience of an international group of hand surgeons.

Abstract: The emergence of the COVID-19 pandemic has severely affected medical treatment protocols throughout the world. While the pandemic does not affect hand surgeons at first glance, they have a role to play. The purpose of this study was to describe the different measures that have been put in place in response to the COVID-19 pandemic by hand surgeons throughout the world. The survey comprised 47 surgeons working in 34 countries who responded to an online questionnaire. We found that the protocols varied in terms of visitors, health professionals in the operating room, patient waiting areas, wards and emergency rooms. Based on these preliminary findings, an international consensus on hand surgery practices for the current viral pandemic, and future ones, needs to be built rapidly.

The management of open tibial fractures in children: a retrospective case series of eight years' experience of 61 cases at a paediatric specialist centre.

Abstract: Aims Following the introduction of national standards in 2009, most major paediatric trauma is now triaged to specialist units offering combined orthopaedic and plastic surgical expertise. We investigated the management of open tibia fractures at a paediatric trauma centre, primarily reporting the risk of infection and rate of union. Patients and Methods A retrospective review was performed on 61 children who between 2007 and 2015 presented with an open tibia fracture. Their mean age was nine years (2 to 16) and the median follow-up was ten months (interquartile range 5 to 18). Management involved IV antibiotics, early debridement and combined treatment of the skeletal and soft-tissue injuries in line with standards proposed by the British Orthopaedic Association. Results There were 36 diaphyseal fractures and 25 distal tibial fractures. Of the distal fractures, eight involved the physis. Motor vehicle collisions accounted for two thirds of the injuries and 38 patients (62%) arrived outside of normal working hours. The initial method of stabilisation comprised: casting in nine cases (15%); elastic nailing in 19 (31%); Kirschner (K)-wiring in 13 (21%); intramedullary nailing in one (2%); open reduction and plate fixation in four (7%); and external fixation in 15 (25%). Wound management comprised: primary wound closure in 24 (39%), delayed primary closure in 11 (18%), split skin graft (SSG) in eight (13%), local flap with SSG in 17 (28%) and a free flap in one. A total of 43 fractures (70%) were Gustilo-Anderson grade III. There were four superficial (6.6%) and three (4.9%) deep infections. Two deep infections occurred following open reduction and plate fixation and the third after K-wire fixation of a distal fracture. No patient who underwent primary wound closure developed an infection. All the fractures united, although nine patients required revision of a mono-lateral to circular frame for delayed union (two) or for altered alignment or length (seven). The mean time to union was two weeks longer in diaphyseal fractures than in distal fractures (13 weeks versus 10.8 weeks, p = 0.016). Children aged > 12 years had a significantly longer time to union than those aged < 12 years (16.3 weeks versus 11.4 weeks, p = 0.045). The length of stay in hospital for patients with a Gustilo-Anderson grade IIIB fracture was twice as long as for less severe injuries. Conclusion Fractures in children heal better than those in adults. Based on our experience of deep infection we discourage the use of internal fixation with a plate for open tibial fractures in children. We advocate aggressive initial wound debridement in theatre with early definitive combined orthopaedic and plastic surgery in order to obtain skeletal stabilisation and soft-tissue cover.

Finkelstein's Test Is Superior to Eichhoff's Test in the Investigation of de Quervain's Disease

Abstract: Introduction de Quervain's tenosynovitis is a common pathologic condition of the hand. Finkelstein's test has long been considered to be a pathognomonic sign of this diagnosis, yet most clinicians and instruction manuals erroneously describe what is in fact the Eichhoff's test, which is thought to produce similar pain by tendon stretching in a normal wrist. The purpose of this study was to compare Finkelstein's test with Eichhoff's test in asymptomatic individuals. Materials and Methods Thirty-six asymptomatic participants (72 wrists) were examined using both Finkelstein's and Eichhoff's tests with a minimum interval of 24 hours between the tests. Results The results showed that Finkelstein's test was more accurate than Eichhoff's test. It demonstrated higher specificity, produced significantly fewer numbers of false-positive results, and also caused significantly less discomfort to patients. Conclusion This study recommends Finkelstein's test as the clinical examination of choice for the diagnosis of de Quervain's disease.

Wrist arthroscopy for the treatment of scaphoid delayed or nonunions and judging the need for bone grafting.

Abstract: This study reports outcomes of arthroscopy in the treatment of delayed or nonunions of 25 scaphoids (25 patients). The surgery was performed between 8 and 43 weeks after injury. Intraoperatively, 11 fractures were deemed stable to probing and underwent percutaneous screw fixation only; 14 were unstable and received arthroscopic bone grafting with percutaneous screw fixation. All fractures united. At a mean follow-up of 21 months (range 12-48), the mean Mayo wrist score was 96, and patient-rated wrist evaluation was 4, and the flexion-extension arc was 90% of the contralateral wrist. We conclude that arthroscopy is valuable in the treatment of scaphoid delayed or nonunions and in judging the need for bone grafting. Our data indicate that regardless of cystic formation in the scaphoid, bone grafting is not always necessary. Percutaneous fixation alone is sufficient when scaphoid delayed or nonunions are between 8 weeks and 1 year following injury, without scaphoid nonunion advanced collapse or dorsal intercalated segment instability, and when forceful probing confirms stability of the scaphoid arthroscopically. Level of evidence: IV.

Wrist terminology as defined by the International Wrist Investigators' Workshop (IWIW)

Abstract: ADAPTIVE CARPUS (FIGURE 1) Fig. 1: ADAPTIVE CARPUS-ADAPTIVE DISI: the distal articular surface of the radius is inclined 30° dorsally from an old impacted distal radius fracture. The lunate is tilted dorsally to account for dorsal inclination of the distal radius, while the capitate is in neutral position following the position of the metacarpals with the hand. Changes in the carpal alignment creates a capitolunate angle of approximately 30° and a scapholunate angle of 85°. The increased scapholunate angle creates a DISI (dorsal intercalated segmental instability) configuration. SYNONYM: none CLINICAL: NA RADIOLOGIC: a carpal malalignment usually identified by a dorsal or volar tilt of the lunate caused by an extracarpal osseous abnormality, usually a distal radial malunion without ligament tears COMMENTS: 1) every carpus must adjust in some way to alterations of the radius articular surface, the ulnar head position, and the shape or size of the carpal bones even if all of its ligaments are intact. Although these alterations of the osseous elements may disrupt the ligament anchorage, may be accompanied by ligament damage, or may secondarily develop ligament attenuation, they often begin as a normal carpus. 2) The carpus may be malaligned between the two rows or remain aligned within itself, while translating at the radiocarpal level to a new position (usually dorsal, sometimes volar, even ulnar or radial). 3) This definition refers to an extracarpal, not an intracarpal, problem. If the malalignment is due to an intracarpal problem, then the case falls into a CID, CIND, or CIC category and would not fit into the category of an adaptive carpus as described here. Any adaptive carpus, by definition, can be solved by an extracarpal intervention that does not require surgery on the carpus. However, with time an adaptive carpus may degenerate to a point that the intrinsic ligaments …

Impact of the COronaVIrus Disease 2019 lockdown on hand and upper limb emergencies: experience of a referred university trauma hand centre in Paris, France.

Abstract: The lockdown imposed in France to cope with the COronaVIrus Disease 2019 (COVID-19) outbreak has led to major changes in the lifestyle of French citizens. The aim of our study was to study its impact on activity related to emergencies in hand and upper limb trauma in comparison to the same reference period in 2019. All consecutive patients consulting for upper limb injury requiring urgent care at Georges-Pompidou European Hospital (HEGP), France, during the lockdown period (case group) and the equivalent period in 2019 (control group) were included. In each group, the type of accident, the anatomical location of the injury, and the treatment were reported and compared. Two hundred seventy-five patients were included in the case group in comparison to 784 patients in the control group. We observed a two-third decrease in the rate of upper limb emergencies (− 64.9%) in particular a drastic drop in the rate of road, work, and leisure accidents (10.4% vs 14.3%, p = 0.1151; 10.0% vs 22.6%, p < 0.0001; 13.1% vs 30.8%, p < 0.0001, respectively), and a clear increase in domestic accidents (66.5% vs 32.3%, p < 0.0001). The aetiologies were more dominated by lacerations of soft tissues (48.4%, vs 38.3%, p = 0.0034) and infections (8.7% vs 5.1%, p = 0.0299) with an increase in the indications for surgical management (51.2% vs 36.9%, p < 0.0001). Conversely, we observed fewer consultations for joint injuries (20.7% vs 30.7%, p = 0.0015) and fractures (22.2% vs 25.9%, p = 0.2210). The lockdown imposed in France has changes the etiologies and the management of hand and upper limb emergencies.
