study morphological features of the glenoid cavity and to measure various dimensions of the glenoid in dry human scapulae bone and correlation to its function.~The knowledge of normal anatomical features and variations of the shape and size of glenoid cavity are prerequisites for complete understanding of the mechanics of shoulder joint, this information has clinical application in shoulder arthroplasty, gleno-humeral instability and rotator cuff tear management.~study morphological features of the acetabulum and to measure various dimensions of the acetabulum in dry human hip bone and correlation to its function.~Knowledge of the dimensions of acetabulum are vital to understand the mechanics of hip joint, and will assist the prosthetists to construct the suitable prostheses
1 - study morphological and morphometric features of the glenoid cavity in human scapulae bone and its function.~2- study morphological and morphometric features of the acetabulum in human hip bone and its function.
