This study investigates the efficacy of the AO Pi-plate in the treatment of complex, unstable, intra-articular fractures of the distal radius. A retrospective study of 17 patients was carried out who underwent open reduction and internal fixation for dorsally displaced, intra-articular fractures of the distal radius using the AO Pi-plate. All patients were assessed clinically and radiologically post-operatively. The final functional outcome was assessed using the Gartland &
Werley scoring system. The average follow-up period was 34.3 months. 94% (16 patients) of the fractures were classified as AO type C fractures. The wrist movement was restored to a near normal range in all cases. The mean grip strength was 67% of the uninjured hand. The functional outcome as measured by the Gartland &
Werley scoring system showed excellent and good results in 88% of the patients. Radiographic assessment revealed an average articular step-off of 0mm post-operatively. The implant removal rate was 29% (5 patients) and the main reason for that was extensor tenosynovitis.
