Background: The complete ossification of the superior transverse scapular ligament is one of the predisposing factor for suprascapular nerve entrapment syndrome and it is a risk factor at surgical exploration during the suprascapular nerve decompression.
Aim: To study the complete ossification of superior transverse scapular ligament and its frequency of distribution in various population of different region.
Materials and Method: 65 dry scapulae were collected and studied with naked eye examination.
Results: Macroscopic observation revealed that 6 scapulae (5-left side, 1-right side) out of 65(9.2%) scapulae had a complete ossification of superior transverse scapular ligament.
Conclusion: This anatomic information is important in the management of suprascapular nerve entrapment neuropathy or interventional procedure at the supra suprascapular nocth.
