Etiology

Suprascapular nerve palsy is an injury to the suprascapular nerve, a nerve root that corresponds to C5- C6 nerve roots of the brachial plexus. Injury to this nerve can occur through many mechanisms, to include, traction injuries to the shoulder; compression along its path at the cervical spine, superior and posterior shoulder. Two locations specific to compression include suprascapular notch ligament and spinoglenoid ligament.



Examination
