Technique of intercostal nerve harvest and transfer for various neurotization procedures in brachial plexus injuries.
Brachial plexus palsy caused by traction injury, especially spinal nerve-root avulsion, represents a severe handicap for the patient. Despite recent progress in diagnosis and microsurgical repair, the prognosis in such cases remains unfavorable. Neurotization is the only possibility for repair in cases of spinal nerve-root avulsion. Intercostal neurotization is a well-established technique in the treatment of some severe brachial plexus lesions in adults. In this article, we describe our experience and technique of intercostal nerve harvest for transfer in various neurotization strategies in posttraumatic brachial plexus reconstruction. Intercostal nerve harvest is a technique requiring meticulous technique and careful dissection along with proper hemostasis. It is also very important to preserve the serratus anterior muscle insertion and keep soft tissue stripping to a minimal. We do not osteotomize the ribs and believe that this adds to the morbidity and length of the procedure. Neurotization using intercostal nerves is a very viable procedure in avulsion injuries of the brachial plexus; however, there is some concern that in the presence of ipsilateral phrenic nerve palsy, it may lead to a significant compromise of respiratory function. In our experience, this is negligible with good long-term results.
