AB: The authors reviewed forty-three surgically managed cases of cubital tunnel syndrome treated during the past twelve years. Surgery had been performed on thirty-one men and twelve women. Their average age was 46.8 years old. The etiology of cubital tunnel syndrome had been determined as follows: There were twenty-three cases of osteoarthritis of the elbow joint. There were four cases of isolated cubitus valgus deformity. There were three cases of isolated cubitus varus deformity. There were three cases of rheumatoid arthritis. One patient had sustained trauma to the cubital tunnel. In nine other patients there were various causes but no joint malalignment. The selection of the surgical technique for the correction of cubital tunnel syndrome was a function of the etiology of the condition. Cubital tunnel syndrome from osteoarthritis was surgically managed with a modified King technique. Ulnar neuropathy with a cubitus valgus deformity was managed with an ulnar nerve anterior transposition. Ulnar neuropathy with a cubitus varus deformity was managed with a neurolysis. The surgical outcome for cubital tunnel syndrome in patients with an angular deformity at the elbow frequently was not optimum. However, although some patients remained symptomatic, the majority of postoperative patients did obtain improved motor strength and conduction velocities. This confirmed the efficacy of surgical management regardless of the cubital tunnel syndrome etiology.
