| Summary: | Introduction: Superior border of scapula is thin and presents
the suprascapular notch. The superior transverse ligament
bridges across the notch, which is attached laterally to the root
of the coracoid process and medially to the limit of the notch.
Notch is converted into foramen, through which passes the
suprascapular nerve to the supraspinous fossa; the suprascapular
vessels. The superior transverse ligament may be completely or
incompletely ossified and it is one of the predisposing factors for
suprascapular nerve entrapment neuropathy.
Aim: To study the ossification of superior transverse scapular
ligament and its clinical importance.
Materials and Methods: The present osteological study was
carried on 77 (34 right side and 43 left side) dry adult human
scapulae of both sexes obtained during undergraduate
teaching from October 2015 to September 2016. Scapulae with
suprascapular foramen were studied. Superior transverse ligament
was observed for complete or incomplete ossification.
Results: The incidence of the suprascapular foramen in the
present study was 3.89% (2.59% completely ossified and
1.29% incompletely ossified superior transverse ligament).
Conclusion: Complete or incomplete ossified superior transverse
scapular ligament may lead to narrowing of the suprascapular
notch forming a foramen and thus give rise to suprascapular nerve
entrapment syndrome. An awareness of suprascapular foramen
is important to the anatomists, radiologists, neurosurgeons and
orthopaedic surgeons. Existence of suprascapular foramen
alters the surgical technique or arthroscopic decompression of
the suprascapular nerve. |
