Abstract

Background Accessory carpal ossicles may be the cause of atraumatic wrist pain or may be misinterpreted as a fracture after a trauma.

Case Description We report the case of a patient suffering with chronic, bilateral wrist pain without history of trauma. Sonographic examination showed a bilateral symptomatic os epilunatum, both of which were surgically resected, resulting in pain relief.

Literature Review Os epilunatum is a rare entity that has been reported only in few cadaveric specimen.

Clinical Relevance Os epilunatum is a rare accessory ossicle of the carpus that can cause this aggravating pain. Sonography enabled accurate diagnosis of this anomaly. Because of possible associated tear of the scapholunate ligament, we recommend intraoperative testing of the stability of the scapholunate joint.
