Suprascapular neuropathy is typically the result of traction damage to the Suprascapular nerve. This nerve arises from the upper part of the brachial plexus, the large number of nerves where they exit the spine at the base of the neck, and travels under the trapezius to the scapular where it supplies the Supraspinatus and Infraspinatus muscles.
Suprascapular Neuropathy and Its Symptoms
Damage to this nerve usually occurs during sports that involve overhead movements. Some of these sports include tennis, cricket and volleyball. Injury to the nerve can happen because of compression, traction or direct trauma. Unnatural movements of the scapula can also cause stretching of the nerve. The growth of cysts resulting from superior glenoid labral tears can compress the nerve as well.
If you think you are suffering from suprascapular neuropathy, you’ll be experiencing these symptoms:
- Aching or burning pain of the shoulder joint.
- Deep pain within the shoulder joint.
- Pain that radiates through the arm.
- Gradually occurring pain.
- Weakness of the shoulder joint into abduction – lifting the arm out to the side – and external rotation.
- Wasting of the Supraspinatus and Infraspinatus muscles.
