OBTURATOR NERVE INJURIES DURING INTRAABDOMINAL SURGERY

Selective obturatory nerve lesions are described to occur relatively infrequent. In the present paper two patients developing signs and symptoms of an obturatory neuropathy as a result of abdominal surgery were reported. In a 48-year-old woman a bilateral obturator neuropathy occurred after bilateral ovarectomy with a weakness of the adductor muscles, typical electromyographic findings and sensory deficits in the medial aspect of the thigh. Similar unilateral signs and symptoms were seen in a 65-years-old man as a result of an aortofemoral bypass operation. Symptomatology and differential diagnosis of obturator nerve lesions are discussed.
