The Effect of Unilateral Intercostal Nerve Transfer upon Lung Function

Abstract

Intercostal nerve transfer is a well-established technique in the treatment of some severe brachial plexus lesions in adults. There is, however, concern that in the presence of an ipsilateral phrenic nerve palsy it may lead to a significant compromise of respiratory function. 20 patients having intercostal nerve transfers had their lung function assessed pre-operatively and 6 weeks postoperatively. The patients were subsequently questioned about symptoms of respiratory dysfunction. There was no evidence that intercostal nerve transfer leads to a significant reduction in respiratory function in adults. It therefore appears safe to perform intercostal nerve transfers in adults following brachial plexus injuries even in the presence of an ipsilateral phrenic nerve palsy.
