The prostheses currently available are based on western database and only few sizes fit into the Asian shoulders. The native database will also help us to calculate humerus bone loss and prostheses designing. Materials and Methods: Sixty seven paired humeri (Left-33, Right-34) were included in study. Adult wet humeri were retrieved from embalmed human cadavers fixed in formalin. The humeral head dimensions and version were measured with fixed protocol. Results: The mean humerus head height, antero-posterior and medio-lateral diameter of both sides was 18.57 ±2.82 mm, 39.65 ±2.97 mm and 43.11 ±3.73 mm respectively. The mean humerus head version on both sides was 37.30 ±7.85 degrees. Conclusion: The smaller dimensions of the proximal humerus in the Asian population need to be contemplated while designing and fitting prosthesis in total shoulder arthroplasty and for assessing bone loss while establishing criteria for anatomic restoration, post surgery.
