Background : The suprascapular notch is a depression at the lateral end of the superior border of scapular blade. In living it is converted into a foramen by bridging its ends by transverse scapular ligament, above which pass the suprascapular vessels and below passes the suprascapular nerve. Entrapment neuropathy is common due to involvement of the nerve occurs here.
Aim and Objective : In this study we have attempted to configure the suprascapular notch of 150 dry human scapulae specimen.
Materials and Methods : The specimen are studied in the Department of Anatomy of Calcutta National Medical College and N.R.S Medical college.
Statistical Analysis used : Non parametric t test (Mann Whitney U test) is done. P value of 0.05 or less is considered to be significant.
Result : Among 150 scapulae 70 were right sided and 80 left sided. The pattern of Suprascapular notch (SSN) were classified both according to Rengachary classification and Natsis’s classification. As per first classification Type II (R = 19, L = 27) was found to be commonest (30.67% of the total), and Type V (R = 3, L = 4) (i.e 4.67% of total) to be least common. As per Natsis’s classification the Type II was most common and Type IV least.
Conclusion : The wide knowledge of shape of suprascapular notch is very important in diagnosis and consequent treatment of suprascapular neuropathy.
