Suprascapular nerve entrapment

A summary of seven cases

of this entity, including both medical and surgical approaches, is discussed. Anatomical Considerations The suprascapular nerve has a long course and originates from the upper brachial plexus where the C-5 and C-6 roots join at Erb's point. In up to 50% of cases, the suprascapular nerve will receive fibers from the C-4 root, but it will rarely arise solely from the distal end of the C-5 root. 13, 29 The nerve extends laterally and deep to the trapezius and omohyoid muscles as it courses with the suprascapular artery on its way to the suprascapular notch

be located by palpating the tubercle of the transverse process of the C-6 vertebra and identifying the artery at its point of entry into the transverse foramen. Exposure of the anterior scalene muscle and the phrenic nerve indicates that the approach is too far lateral. The recurrent laryngeal nerve, the cervical sympathetic trunk, and the lower elements of the brachial plexus must be protected during the surgical exposure. After exposing the common carotid and vertebral arteries, the vertebral artery, as it enters the transverse foramen, is occluded with a

cervical spinal cord injuries resulting in cruciate paralysis were identified between 1984 and 1989. Eleven cases were managed at the Barrow Neurological Institute; three other cases were treated at other facilities and included in this study. Only patients with the definitive clinical features of cruciate paralysis were considered in this review. We excluded from the study patients with severe head injury, brachial plexus or peripheral nerve injuries, severe preexisting diseases involving the upper extremities (such as neoplasm or severe arthritis), extensive fractures
