A STUDY OF MORPHOLOGICAL PATTERNS OF GLENOID CAVITY OF SCAPULA

Abstract

Background: Shoulder arthroplasty offer pain relief and improement in patients of shoulder arthritis. Appropriate fixation of glenoid component of scapula is essential to evade loosening which is the common indication for revision surgery. The glenoid cavity is small and allows only a restricted spot for limited fixation devices. For this reason, knowledge of the morphology of glenoid cavity is important.

Methodology: In the current study, 5 diameters of glenoid cavity of 43 right sided and 57 left sided dried unpaired human scapulae have been measured with the aid of digital vernier callipers.

Results: Various shapes of glenoid cavity like inverted comma, pear or oval based on the glenoid notch have also been observed. The values of glenoid cavity in the current study are lower than those reported in other studies.

Conclusion: These findings suggest that the difference in size of the glenoid cavity in Gujarati population may have to be taken into consideration while deciding the size of the glenoid component in shoulder arthroplasty in this population.
