Anatomical variations in suprascapular notch
Author(s): Dr. Anjali Satyen Sabnis, Prakash Mane
Abstract: 30 dried scapulae of unknown sex and age were studied to see the variations in suprascapular notch. Suprascapular nerve and vessels pass through suprascapular notch which is converted into foramen after bridging by superior transverse scapular ligament. The shape, size of suprascapular notch and ossification of superior transverse scapular ligament is related to entrapment of suprascapular nerve. In the present study out of 30 scapulae, shallow and deep suprascapular notches were seen in 10 and 18 scapulae respectively. In two scapulae ossification of superior transverse scapular ligament was seen to convert into foramen. This incidence is very rare. Knowledge regarding suprascapular notch and its variations will be helpful for orthopedic surgeons during suprascapular nerve decompression procedure.
