Background: Management of hand trauma has evolved to incorporate assessment, treatment and rehabilitation of patients in a ‘one-stop’ clinic on initial presentation. Our aim was to evaluate the effect of coronavirus disease 2019 (COVID-19) on the choice of treatment for hand fractures using inter-rater agreement between surgeons.
Methods: All patients with hand fractures during the COVID-19 lockdown from March to May 2020 were included in the study. Two experienced hand surgeons blinded to management and outcomes independently reviewed radiographic images and relevant clinical history to provide their opinion on optimal treatment. Weighted kappa analysis was performed to determine concordance and inter-rater agreement between the two surgeons and actual management.
Results: The study included 82 patients (62 men and 20 women) with a mean age of 40.3 (SD 19.7). The injuries occurred most often at home following an accident (34%) or a fall (28%). Fractures involved the metacarpals in 29 patients and the distal phalanx in 22 patients. Thirty-five patients underwent surgery, whereas 47 were managed conservatively. Overall agreement between actual management and consultant A and consultant B was moderate (κ = 0.55, p < 0.0001 and κ = 0.63, p < 0.0001, respectively). Subgroup analysis showed a weak agreement between actual management of metacarpal fractures and consultant A and consultant B (κ = 0.22, p = 0.29 and κ = 0.47, p = 0.02, respectively). Inter-rater agreement was substantial for management of metacarpal fractures (κ = 0.73, p < 0.0001), but weak for distal phalanx fractures (κ = 0.29, p = 0.03).
Conclusion: Our study has shown that overall management of hand fractures remained optimised throughout the pandemic. However, a lack of concordance was observed in the management of metacarpals.

Background: Most unstable hand fractures in children are treated by closed methods. If osteosynthesis is required, Kirschner (K)-wires are commonly used, though they carry a risk of injury to the physis. We have been using a mini external fixator system (MEFS) for the treatment of unstable periphyseal fractures of the hand. The aim of this study is to describe the application and report the outcomes of MEFS for the treatment of periphyseal fractures of the hand.
Methods: We retrospectively reviewed all the patients with periphyseal fracture of the hand treated with MEFS from March 2010 to December 2019. Data with regard to age, sex, hand dominance, digit and bone injured, mechanism of injury, medical records and related radiographs were collected. Salter–Harris classification was used to classify epiphyseal fractures and the Al-Qattan classification for categorising neck fractures. Range of motion and residual deformity of the affected fingers were evaluated during follow-up and at 3 months postoperatively.
Results: Fourteen periphyseal unstable fractures were treated using closed reduction and MEFS. Only one patient with a fracture of the neck of the proximal phalanx of the little finger required revision surgery. No patient had pin site infection or pin loosening and the device was well tolerated by all patients. All fractures united and all the patients recovered a full range of motion at final follow-up.
Conclusions: The MEFS is a reasonable alternative for unstable periphyseal fractures with good outcomes and avoids the risk of iatrogenic physeal injury from K-wire fixation.

Metacarpal fractures are a common injury in the hand. When surgical intervention is indicated, there are multiple approaches and techniques of fixation. Intramedullary fixation has become an increasingly versatile method of fixation. The limited dissection needed for its insertion, rotational stability provided by the isthmic fit and lack of requisite hardware removal are improvements over conventional K-wire or plate fixation techniques. Multiple outcome studies have confirmed its safety and effectiveness. In this technical note, we provide some tips that can help surgeons considering intramedullary headless screw fixation of metacarpal fractures.
