Lateral antebrachial cutaneous neuropathy as a result of positioning while under general anesthesia.

As the second most common cause for professional liability in anesthetic practice, nerve injuries are a well-recognized complication. We present a case of lateral antebrachial cutaneous neuropathy after prolonged general anesthesia for left medial meniscal transplant and microfracture surgery. In the orthopedic and sports medicine literature, <100 cases have been described. We discuss the possible causes and propose surgical positioning as the most likely cause of postoperative lateral antebrachial cutaneous neuropathy in our patient.
