ABSTRACT:
Introduction: The suprascapular notch is present on the superior border of the scapula, just medial to the coracoid process. The suprascapular ligament bridges the edges of notch, which sometimes get ossified and convert suprascapular notch into foramen.A narrow notch or excess ossified ligament may have a greater chance of a nerve impingement in the suprascapular foramen.
Materials and methods: This study was conducted on the bones that were obtained from the bone bank of Department of Anatomy. A total of 118 (57 right, 61 left) human scapulae derived from adult (35 male and 17 female) skeletons were evaluated for the shape of suprascapular notch ,presence of any ossification of the suprascapular ligament and classified according to Rengachary et al into I –VI types.
Results: On analysis of morphological variations of suprascapular notch, we found following types of scapulae : Type I -22.42 %, Type II -12.98 %, Type III -53.98 %, Type IV -0 %, Type V- 7.08 %, Type VI -3.54%.. Out of all specimens, in three specimen suprascapular ligaments (3.54 %) were found to be completely ossified
Conclusion: The knowledge of morphometric variations of suprascapular notch and ossification of suprascapular ligament is very important for clinicians. This knowledge is very important in sports medicine as well as for orthopaedic surgeons in management of cases of shoulder pain.
Key words: Suprascapular notch, Suprascapular nerve, Suprascapular ligament, Suprascapular foramen.
