Ulnar styloid process is usually present on the posteromedial aspect of the head of the ulna to the tip of which is attached the ulnar collateral ligament. Its base is the point of insertion of very important triangular fibrocartilage complex. We mention a case report in which the ulnar styloid process is present at the dorsolateral aspect of head of ulna bilaterally as a morphological variation. Case History A 42 years old patient came to us with injury due to fall on the wrist right side. On clinical examination he had mild tenderness at the dorsal aspect of distal radius. He had no swelling or deformity at the wrist. Elbow and hand movements were normal. Wrist movements were mildly painful at the extremes. Radiographs of the affected wrist (AP and lateral views, fig. 1 & 2) were taken which showed no signs of fracture. But the incidental finding was a hypertrophied and dorsolaterally attached ulnar styloid process. The patient had no complaints in the past history. He used to carry out his daily activities without any problems before he sustained trauma to his wrist one week back. He had no associated deformity elsewhere. The elbow joints were normal on palpation and elbow movements were full range. Careful examination of wrists showed decreased ulnar deviation (by 10-15 degrees) and pronation (by 10 degrees) on both sides. Radiographs of both wrists were taken on the same film which showed the finding bilaterally (fig 3).
