“…(12) Some of the authors Vedha et al, Kour et al, Fatima et al also described suprascapular notch according to different alphabetical symbol like shallow U, deep U, V shaped, J shaped & slightly indented notch among Indian population. (14,15,16) Wang et al described the notch by measuring different diameters like vertical & transverse; to classify the different variety of notches. (22) Several authors have also reported about variations such as calcification, bifurcation or trifurcation & hypertrophy of transverse scapular ligament which was also a directly associated with entrapment neuropathy.…”

“…(13) But, other authors have also described the morphological variations of the notch according to their shape like U shaped; V shaped; foramen or absent notch means totally straight superior border. (14,15,16) Though normally the notch is present in the scapula with various morphological features with many clinical implications, but its absence is also seen in some of the scapulae. (17) So, complete absence of suprascapular notch is also thought to be a reason for nerve entrapment as compression of the suprascapular nerve is possible by the superior transverse scapular ligament characterized by diffuse pain in the posterolateral aspect of the shoulder causing weak abduction.…”

BACKGROUND Suprascapular notch is a depression located in the superior border of the scapula near its lateral part, close to the root of the coracoid process. It is bridged by the superior transverse scapular ligament & serves as a path for the suprascapular nerve. The notch is commonly seen in all the scapulae with variable morphology. Sometimes, it is associated with ossified transverse scapular ligament which plays an important role for the suprascapular neuropathies which has been suggested in many previous literatures. But, its absence can also be a reason for nerve entrapment which has been mentioned less frequently. The purpose of this study was to find out the incidence of completely absent suprascapular notch among dry scapulae of north India, especially Gurugram region along with a morphometric evaluation of superior border of scapular where the notch is situated. METHODS One hundred & ten adult dry scapulae of unknown sex from the osteology museum of SGT Medical College, Gurugram, were obtained for evaluation of absence of suprascapular notch in the superior border of the scapulae near the root of the coracoid process by subjective evaluation (visual inspection). We have also done a morphometric evaluation (length) of the superior border of all the scapulae irrespective of the suprascapular notch. Our observations were compared with other osteological studies performed on other population groups. RESULTS Of the 110 scapulae studied, 43 belonged to right side & 67 scapulae of left side. By visual inspection, 13 scapulae (11.8%) were devoid of suprascapular notch on the upper border & rest 88 scapulae (88.81%) had different variety of suprascapular notch. Among the 13 scapulae without suprascapular notch, 8 scapulae (61.5%) were of right side and 5 scapulae (38.46%) were of left sided bone. Apart from this, the average length of the superior border of the scapulae was 42.73 mm. CONCLUSIONS Incidence of completely absent suprascapular notch in our study is 11.8% which will act as a reference point among Gurugram population in north India. Clinicians should keep in mind about complete absence of suprascapular notch which can be a probable reason for the suprascapular nerve entrapment.

Variation in the morphology of suprascapular notch is associated with suprascapular nerve entrapment neuropathy. So, the knowledge about different shapes of suprascapular notch is important for clinicians in understanding the source of the entrapment syndrome. The Shapes of suprascapular notch are of five in types - Deep U Shaped, shallow U Shaped, J Shaped, V Shaped & indented shaped. Deep U shape is most common & Indented is least common type of suprascapular notch. Suprascapular notch is semicircular in shape, situated in the superior border of the scapula just below the base of the coracoid process. Suprascapular notch is converted to the foramen by the attachment of the suprascapular ligament. Suprascapular vessels passes above the ligament & Suprascapular nerve passes below the ligament. In present study morphological data were obtained and classify the suprascapular notch according to their shape. Present study was conducted on 70 dry human scapulae of both sides with unknown age & sex. This study was conducted in the Department of Anatomy, Hind Institute of Medical Sciences, Barabanki. In the Present study Anatomical variation were found in suprascapular notch which included shape, partial & complete ossification of superior transverse ligament.
