Objective: To describe the functional outcome of spinal accessory
to supra-scapular nerve transfer procedure for shoulder abduction following closed brachial plexus injury.
Nerve: The Spinal accessory
nerve consists entirely of motor fibers to the SCM and Trapezius muscle.
We conducted a study to evaluate the hypothesis that the preservation of cervical root branches of the cervical plexus is associated with greater shoulder mobility, less loss of face and neck sensation, and better quality of life (QoL) following functional neck dissection in which the spinal accessory
nerve is spared.
nerve schwannoma involving the jugular foramen.
This subluxation pattern shows manifestation or dysfunction of the tissues involving the brainstem, the vagal nerve or cranial nerve 10 and the spinal accessory
nerve or cranial nerve 11.
The muscles affected are principally those supplied by the spinal accessory
nerve palsy commonly occurs as a result of iatrogenic injury, usually during lymph node excision in the posterior cervical triangle.
Oswaldo Suarez gets the credit for popularizing functional neck dissection where by the spinal accessory
nerve is carefully preserved to the extent where tumor involvement allows.
Direct distal spinal accessory
nerve (SAN) transfer into the suprascapular nerve outside the zone of injury represents our present reconstructive strategy of choice for reinnervation of the supraspinatus and infraspinatus in order to promote shoulder stability and restore active external rotation.
Trapezius dysfunction as a result of spinal accessory
nerve injury is another common cause.
Two nerve transfers, the radial to axillary and spinal accessory
to the suprascapular, are currently used to restore shoulder stabilization and abduction in upper plexus avulsions.
The spinal accessory
nerve came out Thursday at the hands of Brion Benninger, a surgeon at Oregon Health and Science University, for use in the school's neurological studies - research that could expand what we know about the human brain.
