INTRODUCTION: The suprascapular notch (SSN) entrapment neuropathy common in volleyball players presents with dull ache. The current
study aims to find out if any, the correlation between SSN and scapular dimensions and analyse the relation between SSN dimensions and types of
METHOD: 68 dried human scapula were examined for 4 scapular parameters and 2 SSN variables . SSN was classified according to Rengachary’s
method. For analysis mean, standard deviation, Pearson’s correlation and p-value were calculated.
RESULT: 4.4% scapula had ossified superior transverse ligament. 21 (30.9%) scapula had MD > STD, 40 (58.8%) scapula had STD > MD and 4
(5.9%) sacapula had MD = STD. Type III had maximum (36.76%) and type IV had least (4.41%) frequency. The width/depth ratio was highest in
type I.
CONCLUSION: Scapular dimensions had a weekly positive relation with SSN though not statistically significant. SSN dimensions with
STD>MD were more in number than MD>STD.
