title: Lateral Antebrachial Cutaneous Nerve Entrapment After Shoulder Arthroscopy: A Case Report.
abstract: The lateral antebrachial cutaneous nerve (LABCN) is a distal sensory branch of the musculocutaneous nerve that innervates the radial aspect of the forearm. Cases of LABCN injury from trauma and chronic compression have been reported. A case of musculocutaneous nerve injury after a biceps tenodesis has also been reported. This case report describes an LABCN injury and forearm pain after a biceps tenodesis procedure. Using a multifaceted diagnostic approach of electrodiagnostics and magnetic resonance neurography, the site of compression was appropriately localized. The patient ultimately achieved relief after a surgical decompression.
