MRI-Evaluation of Suprascapular Notch Morphometry and Its Clinical Applications

The suprascapular notch, a depression on the lateral part of the superior border of the scapula, medial to the coracoid process, is covered by the superior transverse scapular ligament, which is converted into a foramen. Sometimes it might be ossified forming a complete osseous foramen. The Suprascapular Notch (SN) served as a passage for the Suprascapular Nerve (SSN). Study the morphology of the suprascapular notch and the suprascapular transverse ligament based on MRI, variations in shape and dimensions of the suprascapular notch. A group of 100 patients underwent MRI examination of the scapular region through the period from 10th July 2019 to 15th Feb 2020. Different morphological types of the suprascapular notch were encountered in the study, the most common type was type III, while type I was less common in the study. The symmetry of the morphological feature of SN bilaterally was seen in 51% of the cases. Conclusively, the symmetry of the suprascapular notch is not a constant feature bilaterally.
