title: Peri-articular suprascapular neuropathy.
abstract: Suprascapular nerve entrapment was first described in 1959 by Kopell and Thompson. Although rare, this condition is among the causes of poorly explained shoulder pain in patients with manifestations suggesting a rotator-cuff tear but normal tendons by imaging studies. Suprascapular nerve entrapment may cause 2% of all cases of chronic shoulder pain. Among the many reported causes of suprascapular nerve entrapment, the most common are para-labral cysts, usually in the spinoglenoid notch, and microtrauma in elite athletes. The potential relevance of concomitant rotator-cuff tears remains debated. Less common causes include tumours, scapular fractures, and direct trauma involving traction. Early diagnosis and treatment are crucial to avoid the development of irreversible muscle wasting. Endoscopic surgery to treat the various causes of suprascapular nerve compression has superseded open nerve release.
