Afterwards, the SSA meet the SSN, and when they reached the suprascapular notch they passed inferior to the STSL in parallel and entered into the suprascapular fossa (Fig.
Finnegan (1978:26) defines this variation as the suprascapular foramen (SSF) in which the suprascapular notch is the normal trait, while the variation, a foramen, is only present when it is a complete bridge.
An ultrasound-guided suprascapular nerve block, described by Harmon and Hearty [7], was performed by advancing the needle beneath the transverse scapular ligament into the suprascapular notch within the vicinity of the suprascapular nerve.
Variations in suprascapular notch with or without an anomalous superior transverse scapular ligament is a cause for suprascapular nerve entrapment syndrome.
[1] became the first to describe the presence of an independent ligament extending on the anterior side of the suprascapular notch, below the superior transverse scapular ligament (STSL), which they named the anterior coracoscapular ligament (ACSL) (Figure 1).
It passes between the suprascapular notch and superior transverse scapular ligament into the posterior surface of the scapula, which dominates the supra- and infraspinatus muscles.
Background: The suprascapular notch of scapula is converted into a foramen by superior transverse scapular ligament (STSL) with the suprascapular nerve passing through the foramen and the suprasca-pular vessels passing above it.
The superior transverse scapular ligament (STSL) links the margins of the suprascapular notch. This ligament converts the notch into a foramen through which the suprascapular nerve and, on some rare occasions, the suprascapular vessels pass [1, 2].
Originating from the upper trunk of the brachial plexus, the suprascapular nerve passes through the suprascapular notch, beneath the transverse scapular ligament and sends motor branches to the supraspinatus muscle.
The test indicated right suprascapular neuropathy at the suprascapular notch with supraspinatus and infraspinatus involvement, evidence of mild ongoing denervation and mild chronic neuropathic changes of the suprascapular nerve with absence of right cervical radiculopathy or brachial plexopathy.
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.
