A Morphometric Study of the Suprascapular Notch and its Clinical Significance in the Indian Population
Dr. Sayongdeepa Roy [2] | Dr. Ankita Pal [2]
Abstract: The suprascapular notch is present in the superior border of the scapula, medial to the root of the coracoid process. The morphology of the suprascapular notch varies significantly. Sometimes it is converted into suprascapular foramen by the transverse scapular ligament. The morphological variations of the suprascapular notch may affect the suprascapular nerve and cause nerve entrapment syndrome. In this study, we have measured the superior transverse diameters and maximum depths of suprascapular notches in 100 scapulae and classified them according to the system proposed by Natsis. We found that in 5% of our samples, the suprascapular notch was absent (Type I). In 72% of the bone samples, the scapulae were of Type II (maximum depth < superior transverse diameter). 17% were of Type III (maximum depth > superior transverse diameter) and 6% of Type IV (presence of suprascapular foramen). Type V scapula (presence of both suprascapular notch and foramen simultaneously) was not found. So, in most scapulae, the suprascapular notches were found to be wider rather than deeper. The findings are mostly at par with similar studies done among the Indian population. The study of morphometric parameters of the suprascapular notch is of utmost clinical importance. Different surgical techniques can be explored in this region of the body, keeping in mind the variations found in the Indian population.
