Abstract

PURPOSE: To establish modality of diagnosis and treatment in pisiform injuries by analysis of its clinical experiences. Materials & Methods : Twelve fractures and one dislocation of the pisiform that were followed up for more than twelve months were reviewed retrospectively.
RESULTS
Eight cases had associated injuries on the wrist or hand of ipsilateral side. Eight cases were diagnosed by routine radiography and three cases required additional special radiography such as the supinated oblique view or carpal tunnel view. One case was diagnosed by computed tomography. Cast immobilization was performed in nine cases and three cases underwent internal fixation. Pisiform was excised in one chronic dislocation case. The results were usually satisfactory but two cases showed pisotriquetral arthritis and one of them underwent excision of pisiform.
CONCLUSION
The diagnosis of pisiform injury may accompany some difficulties due to associated carpal injuries. Routine radiography is sufficient for the screening of it if attention is paid and specific radiography such as supinated oblique view or carpal tunnel view may be very useful for confirmation. As conservative treatment alone shows good result, operative fixation is recommended for limited cases. The excision of pisiform is required in case of pisotriquetral arthritis or neglected chronic dislocation.
