Nerve injury at the suprascapular notch affects the innervation of both the supraspinatus and infraspinatus muscles, whereas injury at the spinglenoid notch, which is relatively infrequent, only affects the infraspinatus muscle.
Blockade of the nerve in the suprascapular notch does achieve this, but is associated with a small risk of pneumothorax (8,19,20).
The size and shape of the suprascapular notch may be a factor in suprascapular nerve entrapment.
1) Two anatomical sites described in literature where the suprascapular nerve can be entrapped are at the level of the suprascapular notch and at the spinoglenoid notch.
This classification focused on the inferior shape of the suprascapular notch as well as the degree of ossification of the superior transverse scapular ligament.
The aim of this current study was to quantify suprascapular notches and reevaluate the two different systems of suprascapular notch classification, focusing on interobserver reliability and intraobserver reproducibility.
Photographs of the suprascapular notch were then taken with a digital camera using at a resolution of 640 x 480 pixels.
The type of suprascapular notch was determined first by using the classification system defined by Rengachary and colleagues.
Then the notches were classified using the system used by Ticker and associates, (2) which examines the inferior border of the suprascapular notch separately from the superior transverse scapular ligament.
The data included the suprascapular notch type distributions and average notch area.
2,13-15) For this reason we feel one should look at the inferior border of the suprascapular notch separately from the superior transverse scapular ligament.
The size of the suprascapular notch is thought to play a part in the predisposition for suprascapular nerve entrapment, assuming that a small notch gives a larger chance of nerve impingement than a large notch.
