 en Pisiform Dislocation and Distal Radius Ulna Fracture
Kalande, F. M.

Abstract

Pisiform dislocation is quite rare. In literature since the 40’s little discussion is documented about this. It is quite rare without other carpal bone dislocation. Pisiform dislocates when the wrist is forced into hypertension ;the flexor carpi ulnaris (FCU) tears of the pisiform and pisohamate ligament and or pisocarpitate ligament. Flexor Carpi ulnaris is a very powerful wrist flexor in extension the pisiform acts as a sesamoid bone enhancing its action. During such injury it is pulled in hypertension and displaces proximally or it may thereafter migrates distally. We report a rare condition where dislocation of pisiform is occurring not with carpal fractures or dislocation but with distal radius ulna fracture in a young skeletally immature boy, the treatment and outcome.
