Abstract

Background: A fracture around the finger metacarpophalangeal joint (MCPJ) can be difficult to access. We developed a trans-web approach that could lead surgeons directly to this site. An incision across the web is believed to result in a web contracture. The aim of this study is to present the outcomes of the trans-web approach.

Methods: This is a retrospective study of all patients in whom a trans-web approach was used to fix fractures around the MCPJ in the period from October 2008 and September 2020. The outcomes of the trans-web approach were evaluated by appearance of the scar, presence of pain in relation to the scar, grading web creep, range of motion at the MCPJ and degree of abduction and adduction of the finger. Any complications of surgery were also recorded.

Results: This study included 10 patients with 11 fractures around the MCPJ (6 avulsion fractures and 5 extra-articular fractures). The mean follow-up was 5 months. Skin contractures did not occur in any avulsion fracture case where original or extended trans-web skin incisions were used. However, they occurred in 2 extra-articular cases treated via a trans-web plus a mid-lateral approach. The mean range of motion of the MCP joint in all the patients was 80° (range, 70°–95°). There was a 10° loss of abduction in one patient and temporary sensory disturbance in another patient. Both these patients had been treated with extended incisions.

Conclusions: The trans-web incision is a useful approach for the open reduction of fractures around the finger MCPJ, especially in avulsion fractures of the lateral volar base of the proximal phalanx with minimal risk of scar contracture. The risk of scar contracture is higher when the trans-web incision is combined with a mid-lateral incision for extra-articular fractures.

Levels of Evidence: Level IV (Therapeutic)
