Syndrome of the Nusculocutaneous Nerve in the Shoulder Region

Wasting and weakness of the biceps and brachialis muscles result when the musculocutaneous nerve is compressed. This usually occurs as the nerve passes through the coracobrachialis muscle. An associated sensory impairment on the lateral aspect of the forearm can occur. While a rare occurrence, this syndrome was described initially by Braddom and Wolfe in 1978, based on their experience with three patients.
