Abstract

Purpose: An articular depressed fragment at the base of the middle phalanx can be an obstacle to congruent reduction and stable fixation. This study assessed the outcomes of a transosseous reduction technique combined with locking plate fixation for the treatment of articular depressed middle phalangeal base fracture. Methods: Between 2015 and 2017, seven patients (eight fingers) with intraarticular comminuted middle phalangeal base fracture were included in this study. Mean follow-up was 19 months (range 12–30 months). All patients showed depression of the articular fragment on sagittal computed tomography (CT) scan and were treated with a transosseous reduction technique and dorsal locking plate fixation. Radiographic evaluation was performed to ensure restoration of a concentric articular surface postoperatively. Total active range of motion (TAM) of the finger, grip strength, and the quick Disabilities of the Arm, Shoulder and Hand (quick DASH) score were evaluated at the last follow-up. Complications were also assessed. Results: All fractures obtained bony union with a concentric joint. There was no significant loss of reduction during the follow-up period. The mean active proximal interphalangeal (PIP) joint and distal interphalangeal joint motion arcs at follow-up were 89° and 61°, respectively. Mean TAM of the affected finger and mean grip strength were 94% (range 80–100%) and 94% (range 86–100%) of the contralateral side, respectively. Mean quick DASH score was 2.3 (range 0–9.1). All patients returned to work. No surgery-related complications occurred. Conclusions: This technique provides satisfactory restoration of articular congruence and enables the early joint mobilization of articular depression-type fractures of the base of the middle phalanx. Type of study/level of evidence: Therapeutic, level IV.
