Unusual wrist pain: pisiform dislocation and fracture

Injuries to the wrist can be challenging to the emergency physician. Injuries to the pisiform bone are rare entities, and their diagnosis may be delayed, increasing the morbidity to the patient. The report describes the cases of a 62-year-old woman with a pisiform dislocation and a 35-year-old man with a pisiform fracture. Excision of the pisiform bone was required in both cases, and both patients had good clinical response.
