Mallet fractures: a novel approach to internal fixation using a hook plate.

Department of Hand Surgery, Singapore General Hospital, Outram Road, Singapore 169608, Singapore.


A new treatment of mallet fractures of the distal phalanx is presented. Open reduction and internal fixation was performed using a "hook" plate fabricated from a 1.3 mm AO hand modular system straight plate. This technique avoids the need to place implants or wires through the small avulsion fragment while still being able to achieve a stable "tension-plate" type of fixation construct strong enough to allow protected early active motion of the distal interphalangeal joint. In minimising the need for prolonged splinting, patient comfort is also improved. In a consecutive series of nine fractures, union was achieved in all cases. At an average follow-up period of 17 months, four had excellent and five had good results using the Crawford rating scale. Using the Warren and Norris scale, all patients had a successful result. The final average active range of flexion of the distal interphalangeal joint was 64 degrees and there was no extensor lag.
