Hemi-hamate arthroplasty is a valuable option for subacute dorsal fracture-dislocations of the proximal interphalangeal joint. Various harvesting techniques have been recommended via both anterograde and retrograde directions, both posing some technical challenges. We propose a technique for simplifying the hemi-hamate graft harvest by creating a window of visualization onto the dorsal hamate articular surface. This is achieved by resection of the dorsal-ulnar base of fourth metacarpal and the dorsal-radial base of the fifth metacarpal. This makes it easier to measure and cut the hamate articular surface. It also provides a properly shaped graft that can be inset in the middle phalangeal defect without using backgrafting, and allowing screws to be placed perpendicular to the graft defect to obtain direct compression.
