Introduction: The humerus is largest bone of the upper limb and also defines the human brachium. The shoulder joint is ball and socket joint formed by articulation of hemispherical head of humerus and shallow glenoid cavity of scapula. The sizes of Humeri & Glenoid can impact decision making during surgery for shoulder replacement and shoulder instability. Study of humerus is helpful for providing data and correlation factors which has enormous importance while making prosthesis for replacement surgery.
Materials and Methods: A retrospective study was conducted on 61 cadaveric humeri - 31 from left side and 30 from right side. Length, AP diameter, MLD and head size was calculated using vernier calliper, scale, no elastic thread and osteometer.
Results: The combined length of humerus was 309.84±17.91 mm. Left and right sided length was 308.42±17.859 mm and 311.30±17.91 mm respectively. AP diameter on left and right side was 39.10±2.791mm and 39.54±2.544 mm respectively. MLD combined was 42.959±3.264 mm and head height was 30.92±2.53 respectively.
Conclusion: The morpho-metric dimensions of right side of humerus was more than that of left side.Proper measurements are required when surgical procedures are to be done. More studies should be conducted measuring head height.
