- Abstract
The shortterm effect of neuromaincontinuity resection in obstetrical brachial plexus palsy was evaluated to test the hypothesis that the neuroma does not contribute to useful limb function. Twentysix patients with obstetrical brachial plexus palsy underwent resection of the neuromaincontinuity and interpositional nerve grafting, and 17 patients underwent neurolysis only. The preoperative and postoperative active movement scores were recorded using an eightpoint scale for 15 joint motions in each patient. Data analysis examined the change in total limb motion scores over time within patients undergoing neuromaincontinuity resection and a comparison with those patients undergoing neurolysis. Compared with preoperative assessment, limb motion scores after neuroma resection were significantly decreased at 6 weeks, not significantly different by 3 months, and significantly improved at 12 months postoperatively. In comparison to patients undergoing neurolysis only, limb motion scores after neuroma resection were not significantly different at 3, 6, and 12 months postoperatively. These findings are unlikely to be accounted for by axonal regeneration across interpositional nerve grafts. Nerve regeneration or recovery in the nongrafted segment of the plexus must be sufficient to reproduce preoperative motion. Resection of the neuromasincontinuity in obstetrical brachial plexus palsy does not significantly diminish motor activity. Plast. Reconstr. Surg.102 1555, 1998.
