CPT® Code 25360

An osteotomy of the ulna, as described by CPT® Code 25360, is a surgical procedure aimed at correcting a deformity or realigning the ulna bone. This procedure may be performed on the ulna alone or in conjunction with the radius, 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 techniques can be employed during the osteotomy, 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 necessary to achieve the desired alignment. During the procedure, an incision is made in the forearm at the site of the deformity, allowing for the dissection of soft tissues to expose the ulna. The periosteum, a layer of connective tissue surrounding the bone, is elevated to facilitate access. The bone is then cut using surgical instruments such as a drill, saw, or osteotome, following the predetermined configuration. If necessary, bone grafts may be placed between the cut segments to promote healing and stability. To ensure that the bone edges remain properly aligned, various internal fixation devices, such as pins, screws, or plates, may be applied. Alternatively, an external fixation device can be utilized if indicated. This procedure is critical for restoring proper function and alignment of the ulna, ultimately improving the patient's quality of life.
