A Morphological Study of Suprascapular Notch and Incidence of Ossification of Superior Transverse Scapular Ligament in South Indian Dry Scapulae

Abstract

Introduction:The suprascapular notch is converted into suprascapular foramen by bridging of superior transverse scapular ligament (STSL) on its edges. The structures related to STSL are the suprascapular vessel which passes above and suprascapular nerve which passes below the ligament to reach the supraspinous fossa. The anterior coracoscapular ligament (ACSL) is present below the suprascapular ligament. Ossification of both STSL and ACSL leads to formation of double suprascapular foramen.
