An osteotomy of the radius and ulna is a surgical procedure aimed at correcting deformities or realigning the bones in the forearm. This procedure may involve either the ulna alone or both the radius and ulna, depending on the specific deformity being addressed. The choice of the osteotomy type and its location is determined by the nature and site of the deformity. Various osteotomy techniques can be employed, including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy. Prior to the surgical intervention, the physician utilizes radiographic studies to accurately identify the precise locations for the bone cuts, ensuring optimal alignment and correction. The surgical process begins with an incision made over the deformity site in the forearm, followed by dissection of the soft tissues to expose the ulna. The periosteum, a layer of connective tissue surrounding the bone, is then elevated to facilitate access. Using specialized instruments such as drills, saws, and osteotomes, the bone is cut according to the predetermined configuration. If necessary, bone grafts may be placed between the cut segments to promote healing and stability. To secure the bone fragments in their correct anatomical positions, various fixation methods may be employed, including pins, screws, or plates. In some cases, an external fixation device may also be utilized. This comprehensive approach ensures that both the radius and ulna are properly aligned and stabilized following the osteotomy.
