Abstract

Background Pisiform dislocations are an extremely rare injury. There are reports in the literature of isolated dislocations, but to our knowledge there are no reports of distal radius fractures with associated pisiform dislocations.

Methods and Results We present two cases of isolated pisiform dislocation and distal radius fracture in the adult population. Both patients were managed conservatively with closed reduction in both the distal radius and pisiform, and subsequently achieved good pain relief and progressive return of wrist function.

Conclusion For adult patients with distal radius fractures and an associated pisiform dislocation, successful closed reduction and immobilization can result in symptomatic improvement and return of function.
