A patient has sustained a Brachial plexus injury and presents with a los of elbow flexion as the major functional impairment. After further investigation, it is determined the patient has a non-operable C5, C6 avulsion. The patient presents with a loss of thumb function, elbow flexion, and an internally rotated shoulder.
