Study of Morphological Variations of the Suprascapular Notch in the Indian Population
Journal Title: Indian Journal of Anatomy - Year 2018, Vol 7, Issue 5
Abstract
Anatomy of the suprascapular notch and its variations has clinical relevance in the fields of plastic and reconstructive surgery. The course followed by the suprascapular nerve predisposes it to compression in the suprascapular notch resulting in suprascapular nerve entrapment syndrome.This study is a descriptive study carried over a period of two years in the Department of Anatomy, Armed Forces Medical College Pune, Maharashtra. Ninety one dry completely ossified scapulae of undetermined age and sex available in the bone bank of the Anatomy department were studiedThe suprascapular notches were classified according to the classification given by Rengachary et al. In our study, Type III notch was the most commonly observed as per the Rengachary classification. Type IV was the least commonly observed morphological variation of the suprascapular notch. In six cases suprascapular ligament was completely ossified to convert it into a suprascapular foramen which is classified as Type VI. The measurement of the Superior transverse diameter and maximum depth was done by the Vernier’s digital Calipers. In our study, type III suprascapular notch was the most common whereas type II and type IV turned out to be the least common as only one case of each type was reported. Knowledge in the variations of the morphology of suprascapular notch helps the surgeon attain adequate access to the suprascapular nerve. Adequate access is a prerequisite to effective decompression of this nerve in all cases of suprascapular nerve entrapment neuropathies.
