title: Suprascapular nerve entrapment. Diagnosis and treatment.
abstract: Nine patients were found to have suprascapular nerve entrapment confirmed by electromyographic studies after the diagnosis was suspected. Eight patients who had a surgical release of the suprascapular ligament had good and excellent results. Except in rare cases, a positive electromyogram (EMG) including a delayed nerve conduction (using a coaxial needle) is necessary confirming evidence of the need for surgical treatment. The recommended surgical technique involves detaching the trapezius muscle from the spine of the scapula and opening the space overlying the suprascapular ligament. The trapezius is retracted cephalad while the supraspinatus is retracted caudad. This exposure avoids injury to the spinal accessory nerve and promotes a rapid rehabilitation. Suprascapular nerve entrapment should be suspected and included in the differential diagnosis of ill-defined shoulder pain.
