Abstract

The suprascapular notch is the most common site of suprascapular nerve entrapment, which manifests in disability and pain of the upper limb.The suprascapular nerve entrapment, a possible risk factor being the ossification of the anterior coracoscapular ligament (ACSL), a structure that runs in the suprascapular notch, below the superior transverse scapular ligament.The unique anatomical variation of the suprascapular notch associated with a suprascapular foramen was discovered in one of the 75 analyzed scapulae in the department of Anatomy during the routine study.The suprascapular notch (SSN) is the site where the suprascapular nerve (SN), accompanied by its associated vein, traverses the upper border of the scapulae under the superior transverse scapular ligament (STSL). The corresponding artery runs over the ligament. TheKnowledge of thisrare variation of the suprascapular notch andthe coexistence the suprascapular foramen at the suprascapular regionshould be helpful in arthroscopic and open procedures at the suprascapular region and also the safety of operative decompression for the suprascapular nerve.
