[Post-traumatic dislocation of the ulnar nerve in the cubital tunnel]

Traumatic luxation of the ulnar nerve is not uncommon (the incidence is 16.2%). The aetiologies are congenital, fracture of the medial epicondyle or from a luxation of the elbow. Complications such as friction neuritis or neuropalsy may be seen. Deep intramuscular implantation seems superior to subcutaneous replacement of the nerve. In a 45-year-old woman with a continuous history of neuropalsy of the ulnar nerve, the injury was successfully treated with deep implantation of the nerve into its cubital groove.
