A Morphometric Study On Suprascapular Notch By Multidedector Computerized Tomography

Suprascapular notch located on the superior border of the scapula and just medial to the base of the coracoid process. This notch is covered by superior transverse scapular ligament and is turned into a foramen. Suprascapular nerve passes under this ligament and suprascapular vessels passes together over it. The images of the patients undergone MDCT examination between 2008 and 2009 were used in this study. Total 88 right and left MDCT scapula images obtained from 44 individuals (22 male, 22 female) were used. Suprascapular notch was divided into 5 types from these images. These types; Type 1: with deep and large notch, Type 2: with deep and narrow notch, Type 3: with shallow and large notch, Type 4: with shallow and narrow notch, Type 5: without a notch. In our study, the most common type was with (29,54%) deep, large notch and the least common type was the group (2,27%) without a notch. In addition, the relationship between suprascapular notch and supraglenoid tubercule, superior angle and inferior angle was evaluated.
