Formation of suprascapular foramen as a result of ossification of superior transverse scapular ligament: a case report and short review of the literature

Abstract

Ossification of superior transverse scapular ligament resulting in a bony suprascapular foramen is of fundamental anatomical and clinical importance. In this case report, we describe a special case of a suprascapular foramen. Its specificity lies in foraminal dimensions, resulting in a unique morphometrical pattern in comparison with reported similar cases. This pattern is of great anatomical and clinical importance, because ossification of suprascapular foramen leads to limitation of suprascapular notch, over which suprascapular nerve passes. Ossification can consequently constitute a major predisposing factor for suprascapular nerve entrapment and subsequent neuropathy. Therefore, this anatomic variation should be considered from surgeons and other healthcare professionals.
