Complete Absence of Suprascapular Notch in Dried Human Scapulae in Gujarat Region: A Risk Factor for Suprascapular Nerve Compression

Dr Ukti Desai

Abstract :

The suprascapular notch, a regular feature of superior border of the scapula may be absent in some cases. This can cause suprascapular nerve entrapment neuropathy with clinical symptoms of vague pain on the superolateral aspect of shoulder, weakness of abduction and external rotation of ipsilateral arm and atrophy of supraspinatus & infraspinatus muscles. The purpose of this study was to find incidence of complete absence of suprascapular notch in Gujarat region. 200 (Right-98, Left-102) dried human scapulae were examined for the absence of the suprascapular notch. 16% (32 in 200) scapulae presented with absence of suprascapular notch.(Right-17, Left-15) The regional variations in the incidence of complete absence of suprascapular notch and its involvement in suprascapular nerve entrapment neuropathy should be kept in mind during surgical or arthroscopic shoulder procedures.
