Single-Stage Reduction of Neglected Perilunate Dislocation: A Case Report

Abstract

Neglected perilunate dislocations are rare and challenging injuries. We report a 59 days old perilunate dislocation in a 55 year old right-handed male. X-ray and CT imaging revealed a dorsal perilunate dislocation with no additional fractures and no increased density or microarchitectural collapse of the lunate or scaphoid. A single-stage open reduction and internal K-wire fixation procedure through a dorsal and volar approach was done. Eighteen months after the procedure, the patient was pain free during movement and had a ROM of 70%. His grip strength was 80.8% the opposite side and the Mayo wrist score was calculated 75. Full range of finger movement was achieved and he carried out his routine without any other complication.
