Such lesions may be missed in the emergency room because of the complex anatomy of the carpal region. The usual circumstances leading to fracture of the pisiform bone include fall with reception on the hyperextended wrist, traffic accidents, and blunt trauma. The purpose of this work was to present a case of bilateral fracture of the pisiform bones. A 34-year-old woman presented with pain along the ulnar borders of both wrists after a fall. The mechanism of fracture was direct trauma on both hands after reception in radial inclination. The diagnosis was established late and conservative treatment was applied. After simple immobilization, the clinical and functional outcome was excellent. The anatomic position of the pisiform bone exposes it to direct trauma. Late diagnosis can favor osteoarthritic sequelae involving the pisotriquetral joint. DOI: 10.1016/s0035-1040(07)78471-4
