Abstract :Shoulder arthroplasty surgery is frequently performed to restore shoulder joint function in many pathologies. The morphology of the humeral head should be considered in the design of the shoulder prosthetic components to improve outcomes of shoulder arthroplasty surgery. Therefore, this study aimed to evaluate the morphometry of the humeral head in order to determine the correct dimensions of the prosthetic components used in shoulder arthroplasty. The present study examined 101 human dry humeri (52 right, 49 left sides) of unknown age and sex. Humerus length, vertical and transverse diameter of humeral head, height of humeral head and distance between the highest point of the humeral head and greater tubercle were evaluated. The mean humerus length was measured 31.05 ± 2.01 cm. The mean vertical diameter of the humeral head was found to be 43.64 ± 3.79 mm, and the transverse diameter was measured as 39.17 ± 3.35 mm. The findings of the present study indicate that the shape of the humeral head is elliptical rather than spherical. The height of the humeral head was measured at 19.49 ± 2.97 mm. A statistically significant discrepancy was observed in the height of humeral head between the two sides (p<0.001). The distance between the highest point of the humeral head and the greater tubercle was found to be 6.79 ± 1.53 mm. The findings of this study were in concordance with the results of other anatomical investigations of the humeral head. The results of the present study have the potential for application in the design of future prosthetic shoulder systems.
