Background:
Morphometric analysis of the glenoid fossa is crucial for understanding shoulder biomechanics, guiding orthopedic procedures, and designing population-specific implants. Accurate anatomical data can improve prosthesis fit and reduce surgical complications. This study aimed to evaluate glenoid fossa dimensions in the adult Indian population using computed tomography (CT).
Methodology:
This retrospective observational cross-sectional study reviewed CT thorax or HRCT thorax scans of 100 adults without shoulder pathology. Scans with deformities, prior shoulder surgeries, fractures, or scapular abnormalities were excluded from the study. Standardized CT measurements included: Glenoid length (SI), glenoid width (AP1), width at notch level (AP2), depth (DGC) circumferenece (PGC), and glenoid cavity index (GCI). Descriptive statistics and comparative analyses for sex and side differences were performed.
Results:
A total of 100 glenoid fossae were analyzed (age range 18–90 years). Mean SI was 33.9 mm, AP1 was 22.87 mm, AP2 was 17.11 mm, DGC was 1.57 mm, PGC was 116.9 mm, and GCI was 67.32. Males showed significantly larger dimensions than females (
Conclusion:
This study provides baseline CT-based morphometric data on the glenoid fossa in the adult Indian population. Recognizing sex-based and side-specific variations is important for surgical planning and implant design to improve clinical outcomes.
