Objectives: The morphological features of the anatomical structures at the proximal end of the humerus are significant in surgical applications and anthropology.So, morphometric measurements of the anatomical structures at the proximal end of the humerus were determined with Microscribe- G2X.Finding of the morphometric data is aimed. Methods: In our study, we used 25 left and 25 right humerus from Akdeniz University Faculty of Medicine, Anatomy Laboratory. proximal end of the humerus ; width and length of the greater tubercle with the lesser tubercle,length of the humerus,sagittal, vertical and transverse diameter of anatomical neck with surgical neck and distance between greater tubercle and lesser tubercle were measured with Microscribe-G2X. Descriptive analysis was applied to dataset and the results were presented as mean±standard deviation. Independent Samples T test was performed for comparison of quantitative variables with normal distribution. Mann-Whitney U test was used for comparison of quantitative variables with non-normal distribution. The overall data were analyzed with the Statistical Package for the Social Sciences (SPSS) 13.0 and a p-value greater than 0.05 was considered statistically significant. Results: According to the measurements of the anatomical structures at the proximal end of the left and right humerus means and standard deviations were: The length of Humerus: on the left 29.58 cm±2.13 / on the right 30.95 cm±1.66. The distance between greater tubercle and lesser tubercle: on the left 2.17 cm±0.27/on the right 2.54 cm±0.28. The width of greater tubercle: on the left 2.61 cm±0.40 / on the right 2.86 cm±0.37. The width of lesser tubercle: on the left 1.59 cm±0.35 / on the right 1.76 cm±0.32. The length of greater tubercle :on the left 2.83 cm±0.28 / on the right 2.98 cm±0.39. The length of lesser tubercle: on the left 2.01 cm±0.29 / on the right 2.02 cm±0.30. The vertical diameter of anatomical neck: on the left 4.24 cm±0.35 / on the right 4.53±0.41. The transverse diamater of anatomical neck: on the left 3.93 cm±0.29 / on the right 4.09 cm±0.43. The sagittal diameter of surgical neck: on the left 2.34 cm±0.29 / on the right 2.47 cm±0.27. The transverse diamater of surgical neck: on the left 2.56 cm±0.26 / on the right 2.67 cm±0.22, respectively. The average of the distance between greater tubercle and lesser tubercle at the proximal end of right humerus was found statistically higher compared to the proximal end of left humerus (2.54 cm±0.28; 2.17 cm±0.27; p=0.001). Conclusion: We think that these measurement will be helpful for surgeons and anthropologists.
