Introduction: In the complex anatomy of shoulder joint one of the articular surfaces is the truncated glenoid fossa. The objective of the study is to observe the shape of the glenoid fossa and perform morphometric study in detail in the dry scapulae.
Materials and Methods: The study was conducted on 38 dry human scapulae of unknown age and sex. The shape was observed & measurements were recorded with the help of digital vernier calliper.
Result: Pear shape glenoid fossa with shallow notch was seen in 55.26% of right scapula and 26.31% of left scapula, while pear shape glenoid fossa with a deep notch was seen in 5.26% of right scapula and 13.1% of left scapula. There was no significant difference between the mean transverse diameters of right and left glenoid fossa. The mean vertical diameter was larger than other diameters.
Conclusion: The glenoid fossa is largely pear shaped because the superior transverse diameter is less than the inferior transverse diameter. The notch on the anterior margin of glenoid fossa due to the tendon of subscapularis may be shallow or significantly deep. The depth of the notch does not correlate with the handedness of the individual. The range of the overall dimensions of the glenoid fossa with deep anterior notch are larger. Morphological and morphometric observations of the study are important in prosthesis design of glenoid fossa and demography of other shoulder diseases.
