title: Intermediate Type of Obstetric Brachial Plexus Palsy.
abstract: Data of 829 infants with obstetric brachial plexus palsy were reviewed to identify any cases that could not be fitted into the any of the well-known types of palsy. These unusual cases were studied in detail with regard to clinical presentation and electrophysiological findings as well as management and spontaneous motor recovery. Erb's, extended Erb's, and total palsies were seen in 42.8%, 28.8%, and 28.0% of cases, respectively. Three cases (0.4%) did not fit into any of the classic types. One case had bilateral palsy, and the remaining 2 cases had unilateral palsy. All affected limbs presented with "abducted arms," "flexed forearms," and electrophysiological evidence of denervation of shoulder adductors and triceps. All cases had excellent spontaneous recovery within 6-12 months. It was concluded that these cases represent mild "intermediate" types of palsy in which the C7 root was the predominant site of injury. Good spontaneous recovery is expected.
