Suprascapular neuropathy or suprascapular nerve entrapment occurs if the suprascapular nerve is compressed as it passes through the suprascapular notch or spinoglenoid notch.
Clinical presentation
Non-specific posterior shoulder pain and weakness.
Pathology
Aetiology
- masses (e.g. ganglion cyst, paralabral cyst, tumour) in the suprascapular or spinoglenoid notch
- traction injury (from sports with overhead action)
- direct trauma
- scapular or humeral fractures (e.g. bony fragments, callous formation)
- anterior shoulder dislocation
- complete and retracted supraspinatus tendon tear
Radiographic features
MRI
- direct features of entrapment 3
- swelling, increased size and signal of the nerve
- visualisation of the causative factor
- indirect features of entrapment via features of muscle atrophy or acute denervation 3
- supraspinatus and infraspinatus muscles: compression at the suprascapular notch
- infraspinatus muscle only: compression at the spinoglenoid notch
- +<li>complete and retracted supraspinatus tendon tear</li>
