Objective: The bone on the inside of the forearm bones is the ulna. The bones of the forearm have very important functions during many movements in daily life activities. The most important of these is the forearm movements made through the elbow joint. The ulna has an important function in the elbow joint, which it forms together with the radius and humerus. Damages in the elbow joint, especially in the ulna, resulting from falling affect life negatively. Materials and Methods: In the study, morphometric measurements were made on dry ulna bones with the help of caliper. In addition, classification was made according to the articular surface of the ulnar notch. Results: Measurements of 32 right and 29 left proximal ulna; In the right ulnas, the Type I ulna rate was 59.37%, the Type II ulna rate was 31.25%, and the Type III ulna rate was 9.37%. In the left ulna, these rates were 51.72% in Type I, 31.03% in Type II and 17.24% in Type III. Conclusion: We think our study will contribute significantly to standardizing the values obtained in dry bone studies. In addition, proximal ulna morphometry is important in surgical interventions to the elbow joint, especially to the ulna. In this respect, we believe that it will contribute to the literature.
