Abstract

The aim of this study was to review the clinical outcome and complications in patients who underwent distal interphalangeal joint (DIPJ) fusion in extension using an axial screw with variable thread pitch (Mini-Acutrak® screw Acumed, LLC, Hillsboro, OR, USA). Thirty-eight cases of DIPJ or thumb IPJ were performed and assessed through patient satisfaction (hand function and pain) and radiographs. The quick-DASH scores were assessed at a mean follow up of 8 months (range : 6 to 12 months). Ninety-three per cent of participants reported good or excellent functional outcome, with Quick DASH scores of less than 30. There were five complications noted (one superficial wound infection ; two fractures ; two screw cut-outs). All cases progressed to radiographic bony union at six months.
