Introduction: The ulna is medial to the radius in the supinated forearm.The ulna in its whole length is slightly convex posteriorly making an anterior angle in the sagittal plane. The proximal ulna shows angulations in the coronal plane on the dorsal surface known as varus angulation. The angle between the posterior and superior surface of olecranon is olecranon angle. The aim of the present study is to provide osteometric data of proximal ulnar angulations and dimensions which will help in designing ulnar plates for reconstruction of proximal ulnar fractures.
Methods: Present study was conducted on 23 right and 25 left side dried ulna bones. Angles were measured with a goniometer and other linear parameters with vernier callipers.
Results: The mean length of ulna was recorded as 25.9 ± 1.63 cm (right) and 26.07 ± 1.67 cm (left). The mean maximum varus angle was observed as 11.91 ± 2.350(right)& 10.21±1.990(left)sides. The mean maximum anterior angle was observed as 8.13 ± 2.890 and on the left 6.87 ±3.020. The mean olecranon angle was 105.95 ± 4.990 (right) and 105± 5.980 (left). Mean mid shaft thickness was1.33 ± 0.20 cm (right) and 1.46± 0.18cm(left).
Conclusion: Considerable variations were found in the parameters measured for the proximal ulna so it is concluded that the data collected in the present study would be of importance in catering the ulnar plates according to the angles and dimensions of ulna.
