Topic: Suprascapular nerve


In the News (Tue 2 Dec 08)

  
  Suprascapular nerve - Wikipedia, the free encyclopedia
The Suprascapular arises from the trunk formed by the union of the fifth and sixth cervical nerves.
It runs lateralward beneath the Trapezius and the Omohyoideus, and enters the supraspinatous fossa through the suprascapular notch, below, the superior transverse scapular ligament; it then passes beneath the Supraspinatus, and curves around the lateral border of the spine of the scapula to the infraspinatous fossa.
Suprascapular paralysis is a common condition in veterinary medicine.

 eMedicine - Nerve Entrapment Syndromes : Article by Dachling Pang, MD, FRCS(C), FACS
The suprascapular nerve arises from the lateral aspect of the upper trunk of the brachial plexus, runs across the posterior triangle of the neck together with the suprascapular artery and the omohyoid muscle, dips under the trapezius, and then passes through the suprascapular notch at the superior border of the scapula.
This almost 90-degree kink of the nerve often is exaggerated by a thickened ridge in the iliacus fascia as it attaches to the posterior aspect of the inguinal ligament.
To avoid kinking the nerve at both ends of the transposition, a block of the intermuscular septum is removed in the proximal end, and the aponeurosis and muscles fibers of the flexor carpi ulnaris are split longitudinally between the 2 heads.

The main symptom of suprascapular nerve entrapment is deep and diffuse pain poorly localized in the posterior and lateral aspects of the shoulder.
The radial and suprascapular nerves have common root origins with an overlap of radiation down the radial nerve to the region of the common extensor group.
Entrapment of the suprascapular nerve must be differentiated from inflammatory conditions of the shoulder.

A lesion of the suprascapular nerve at the spinoglenoid notch is implied.
Suprascapular nerve entrapment is an acquired neuropathy secondary to compression of the nerve in the bony suprascapular notch.
Nerve lesions are frequently overlooked in the differential diagnosis of shoulder pain, and there have been few reports in the literature of injuries of the supracapsular nerve that involve only the infraspinatus.

 Diagnosing Suprascapular Neuropathy in Patients With Shoulder Dysfunction: A Report of 5 Cases   (Site not responding. Last check: 2007-10-25)
The suprascapular nerve is a mixed motor and sensory nerve arising from the upper trunk of the brachial plexus with contributions primarily from the anterior primary rami of the C5 and C6 nerve roots.
Repetitive scapular movements may cause traction or tethering of the nerve, because the suprascapular nerve is fixed proximally at the cervical spine and distally at the scapula as it passes through the suprascapular notch and around the spinoglenoid notch.
Nerve conduction studies for the suprascapular nerve typically measure latency to the infraspinatus or supraspinatus muscle.

CTS stems from extraneural compression on the median nerve underlying the transverse carpal ligament at the wrist (figure 1), caused by tendon or ligament hypertrophy, synovitis, and synovial edema.
the cause of neuropathy was described as an ulnar nerve neuroma with an intraneural degenerative cyst extending from the intermuscular septum to the cubital tunnel.
The remaining cases of high radial nerve palsies were caused by compression of the nerve at the lateral head of the triceps, either from fibrous bands or from the fibrotendinous arch at the lateral head of the triceps.

 The Journal of Bone and Joint Surgery
Suprascapular neuropathy is an uncommon cause of shoulder discomfort and disability.
Treatment for compression of the infraspinatus branch of the suprascapular nerve has included rest, nonsteroidal anti-inflammatory medication, and physical therapy; open excision of the cyst; arthroscopic decompression of the ganglion and repair of the posterior-superior capsulolabral complex; and ultrasound or computed tomography-guided aspiration.
Antoniadis et al., in a report of twenty-eight consecutive cases of suprascapular neuropathy in twenty-seven patients who were seen over a ten-year period, described only three cases of mass lesions causing nerve compression; all of the lesions were ganglia and were in the spinoglenoid notch.

 eMedicine - Infraspinatus Syndrome : Article Excerpt by Jonathan C Reeser
The suprascapular nerve (SSN) is a mixed nerve that provides the motor innervation of the supraspinatus and infraspinatus muscles and the sensory and proprioceptive innervation of the posterior aspect of the glenohumeral joint, as well as the acromioclavicular joint, subacromial bursa, and scapula.
The nerve arises from the upper trunk of the brachial plexus and is composed predominantly of C5-C6 level fibers.
The nerve then passes dorsally through the suprascapular notch, where it is retained by the transverse scapular ligament, into the suprascapular fossa, where 2 motor branches to the supraspinatus muscle originate.

 Suprascapular Nerve Entrapment
While direct trauma to the suprascapular nerve is the usual cause (direct blow to the base of the neck or posterior shoulder, shoulder dislocation or fracture), the problem may result from overuse injuries such as repetitive tennis serving or spiking of a volley ball, excessive horizontal adduction, weight lifting, backpacking or for no apparent reason.
It passes through the suprascapular notch which is covered by the transverse scapular ligament into the supraspinous fossa where it supplies the supraspinatus muscle.
Treatment of the suprascapular injury is directed at rehabilitation (strengthening and flexibility) of the supraspinatus, infraspinatus, and scapular rotators.

Patients and controls underwent a series of 3 indirect suprascapular nerve blocks at 7 day intervals using either 10 cc bupivacaine 0.5 (Marcaine) in the treatment group or 10 cc of physiological saline in controls.
The use of bupivacaine suprascapular nerve blocks was effective in reducing the pain of frozen shoulder at one month.
Clinical studies with a larger number of subjects and a longer study period will help determine the duration and nature of the effect of bupivacaine suprascapular nerve blocks in treating the pain, disability, and glenohumeral joint contracture of frozen shoulder.

Suprascapular nerve dysfunction is associated with massive rotator cuff tears and may be an explanation for fatty muscle atrophy and pain.
Prior anecdotal observation has identified suprascapular nerve injury in association with massive rotator cuff tear (MRCT), and anatomical study suggests this is due to traction on the nerve when the torn tendon retracts.
Surgical treatment was based on the degree of functional deficit and consisted of an arthroscopic partial repair of the posterior portion of the tendon tear in 3, complete arthroscopic repair in 1, arthroscopic debridement in 1, and latissimus transfer in 1.
