Severe Tardy Ulnar Nerve Palsy caused by Traumatic Cubitus Valgus Deformity: Functional Outcome of Subcutaneous Anterior TranspositionFrom the Department of Orthopaedic Surgery, Imam University Hospital (Affiliated to Medical Sciences, University of Tehran), Tehran, Iran Correspondence: S.M. Javad Mortazavi, MD, Department of Orthopaedic Surgery, Imam University Hospital, Medical Sciences, University of Tehran, End of Keshavarz Blvd., Tehran 1419733141, Iran. Tel.: +982166935512; fax: +982166935512. E-mail: smjmort{at}yahoo.com, mortazsm{at}sina.tums.ac.ir. Ten male patients with McGowans grade III ulnar neuropathy due to traumatic cubitus valgus deformity underwent anterior subcutaneous ulnar transposition. Evaluation was performed using subjective and objective measures, and a modified Bishop score. After operation, subjective sensory and motor disturbances were improved or resolved in most of the patients, while objective measures improved less well. Improvement in two-point discrimination (2PD) was consistently associated with symptom relief. All of the patients reported satisfaction with the operation. There were no complications or recurrences. The results of ulnar nerve transposition in our patients were comparable to the results of this operation in patients with severe idiopathic cubital tunnel syndrome. Although the outcome of surgery is not always satisfactory in severe ulnar neuropathy, symptom relief may justify performing the operation.
