Functional Recovery of Posterior Interosseous Nerve Injury Treated With a Nerve Conduit: A Case Report

In peripheral nerve injuries, autologous nerve grafting is often performed when direct anastomosis is difficult, but in cases involving sensory nerves, nerve conduits may be useful. However, there are few reports on the use of nerve conduits for motor nerve injuries. In this case, we used a nerve conduit to treat a posterior interosseous nerve injury, which is a predominantly motor nerve, and achieved relatively favorable results. This case suggests that nerve conduits could be useful for small-gap, thin motor nerve defects, especially when the injury is close to the neuromuscular junction.
