Morphometry of suprascapular notch in Egyptian dry scapulae and its correlation with measurements of suprascapular nerve safe zone for clinical consideration

ABSTRACT

The suprascapular notch is bridged by a superior transverse scapular ligament (STSL) and serves as a passage for the suprascapular nerve. The purpose of this study was to group suprascapular notches (SSN) and provide data on the association of the safe zone distances of the suprascapular nerve. Sixty-five Egyptian dried scapulae were classified into five groups; measurement of dimensions of SSN and measurement of safe zone for the suprascapular nerve were taken. The collected data were analyzed and the correlated parameters in the prevalent types of notches were done.Scapulae were classified into five groups of which the most prevalent groups were Type III (47.63%) followed by Type I (40%). The mean measurements of 'safe zone' distances vary according to the type of notch and correlate with notch dimensions. The present work displayed the anatomical variants of SSN and analyzed the measurement of safe zone distances to help the clinicians to manage different pathological conditions of the shoulder, in order to avoid iatrogenic injury
