The trifid superior transverse scapular ligament: a case report and review of the literature.
During dissection of a 75-year-old Caucasian female cadaver, a trifid superior  transverse scapular ligament (STSL) was found. The suprascapular nerve and  vessels ran inferior to the STSL though the suprascapular notch. Measurements  of the structures of the suprascapular region were taken using two complementary  but independent methods: a classical method using an electronic digimatic  calliper and a new one based on an analysis of digital photographic  documentation of the STSL. The knowledge of anatomic variations of the STSL  is important because this structure is the most commonly recognised possible  predisposing factor of suprascapular nerve entrapment and can be helpful in  diagnosis and surgical and arthroscopic treatment of this pathology.
