Suprascapular Nerve Entrapment by a Trifid Superior Transverse Scapular Ligament

Abstract

Anatomical variations at the suprascapular notch may limit the available space for the suprascapular nerve (SSN), and cause its entrapment in the tight osseoligamentous tunnel. The author encountered the presence of a trifid superior transverse scapular ligament (STSL) while operating on a patient with SSN entrapment. Surgical division of the three bands resulted in complete regression of symptoms.
