Abstract
Bilateral bipartite lunate is a very rare congenital anomaly of the lunate. A 36-year-old military European male was referred to our service diagnosed with a lunate fracture. Symptoms began 3 months before our encounter, after falling on his outstretched left hand. The patient was misdiagnosed with a lunate fracture, therefore treated with a cast and then transitioned to a removable splint over 2 months in total; When the patient presented to our facility, on physical examination, he referred pain over the dorso-ulnar side of the wrist, especially the ulnar snuff. Tenderness to palpation over the fovea and positive triangular fibrocartilage complex axial compression test was encountered. Bilateral wrist X-rays were taken, and a diagnosis of bilateral bipartite lunate was made by our team. The patient was treated for ulnar-sided wrist pain with steroid injection and physical rehabilitation. A literature review on bipartite lunate was conducted, and cases share three basic common features: unilateral involvement, incidentally diagnosed after a traumatic event, and absence of positive clinical findings related to the bipartition.
