Complete traumatic extrusion of the distal ulna through the hypothenar eminence: a case report.

We present a case of complete traumatic extrusion of the distal 40% of the ulna through the hypothenar eminence in the context of an open, both-bone forearm fracture and spinal cord transection. To the best of our knowledge, this specific trauma is unique to the literature, and, therefore, there is no standard treatment approach. Our patient was managed with irrigation and débridement along with open reduction and internal fixation of the radius fracture. No reconstruction of the ulna was performed. The patient reported excellent functional results at 13-month follow-up.
