The indications for ulnar humerus fracture surgery are a displaced fracture and a severely comminuted fracture. Patients with ulnar hawksbill fractures can undergo ulnar hawksbill fracture osteotomy and reduction if the epiphyseal injury has not healed and the proximal end of the fracture is completely displaced. If the patient has a severely comminuted fracture with an intact semilunar notch and distal coronoid process, the fracture block can be resected, and if a layer of bone cortex cannot be preserved at the triceps tendon stop, the triceps tendon can be turned down and secured in the distal burr hole. A fall or direct blow to the back of the elbow can result in an ulnar hawksbill fracture, which presents as swelling and tenderness in nondisplaced fractures and more extensive swelling in displaced fractures. The presence of ulnar humerus fracture can be examined by X-ray to check the characteristics of ulnar humerus fracture, and further by CT, three-dimensional reconstruction of bones and other tests to accurately determine the displacement of the bone, and follow the doctor’s instructions for standardized treatment, in order to avoid adverse effects.
