Can Prophylactic Foraminotomy Prevent C5 Palsy

C5 palsy (C5P) is a well-known, although rare complication of cervical spine decompression surgery. In severe forms, C5P causes debilitating upper extremity weakness involving the deltoids and/or biceps brachii muscles, ultimately diminishing these patients' quality of life. Furthermore, about half of patients with C5P present with sensory deficits and/or intractable pain in addition to the muscle weakness. Prophylactic bilateral foraminotomy at the C5 level during cervical decompression surgery has been studied recently with the hope that it will minimize the risk of developing a C5 nerve root palsy postoperatively. Although the current literature provides some support for this claim, there are insufficient data establishing this technique as a proven measure to reduce the incidence of C5P. In the present study, we seek to evaluate the effect of bilateral foraminotomy on postoperative
