ABSTRACT

Background: Suprascapular notch is an indentation in the superior border of the scapula which is just medical to base of the coracoid process. The superior transverse scapular ligament (STSL) ossifies to form suprascapular foramen and serves as passage for suprascapular nerve. Morphological variations of SSN play a crucial role in the suprascapular neuropathy due to nerve entrapment.

Objective: To study variations of suprascapular notch in dry scapulae and to find out and compare the incidence of ossified STSL/ suprascapular foramina with previous studies from different regions.

Materials and Methods: The present study was conducted on 106 dry human scapulae of unknown age and sex in the Department of Anatomy, ACPM Medical College, Dhule. This was an observational study over a period of nine months from July 2016 to March 2017.The scapulae were examined to assess morphological variations of SSN and various types were classified as per Rengachary et al. The results of present work were compared with previous studies.

Result: Complete ossification of STSL leading to foramina (Type VI) was observed in 09(8.5%) out of 106 scapulae. The most frequent type seen was Type III in 43(40.6%) scapulae, second most common- Type I-26.4%, and rest were Type II-17%,Type IV-4.7%, and Type V-2.8% .

Conclusion: Better understanding and thorough knowledge of variations of suprascapular notch vis-à-vis ossified STSL leading to foramina is important for anatomists and clinicians (surgeons and orthopedics) for making proper diagnosis of suprascapular neuropathy and planning the most suitable surgical corrections.

Key words: Suprascapular Notch, Foramina, Superior Transverse Scapular Ligament, Neuropathy, Scapula.
