Abstract

Introduction: The detail understanding about discrepancy in anatomy of glenoid cavity like different shape, size and dimensions are important for orthopaedicians and prosthetic designers. Studies concerning glenoid morphometry among south Indians are scarce. Present study aims at obtaining anthropometric data of glenoid cavity in south Indian scapulae. Materials and Methods: A total of 72 dry adult unpaired scapulae of unknown age and sex were used in the study. Shape and diameters of glenoid fossa in each scapula were recorded and analysed statistically. Results: The average vertical diameter of glenoid fossa was 37.1mm on right side and 37.3mm on left side. The average transverse I and II diameter was 23.3mm and 17.4mm on right side, 23.3mm and 17.7mm on the left side. The average spino-glenoid depth was 16.9 and 16.3mm on right and left side. The average Coraco-glenoid distance was 25.1mm on both sides. The average acromio-glenoid distance was 32.2 and 32.6mm on right and left side. Glenoid index was 63.2% on the right side and 62.4% on the left side. Conclusion: The findings of this study would assist to design proper size of glenoid component to be used in total shoulder arthroplasty among south Indians.
