Treatment of right proximal ulnar-radial osseous fusion can be performed by separating the interosseous union of the ulnar-radial bones or radial osteotomy and refixation. 1. Separation of the interosseous union of the ulnar radius: The symptom of ulnar radius fusion is rotational dysfunction of the forearm. A tipped fascial flap is placed over the interosseous union to prevent recombination of the interosseous union of the ulnar radius and to correct the rotational deformity disorder. 2. Radial osteotomy and refixation: An incision is made near the radial side to find the bony union of the proximal ulna and radius, and the proximal ulna is osteotomized. Wide fascia can be taken for filling to prevent the proximal ulna-radius bony union again. It is recommended to follow the doctor’s instructions strictly, eat a healthy diet and take rest after the surgery is completed. During the recovery period, you should keep your mood happy and ask your doctor immediately if any discomfort occurs, so as not to delay your condition.
