CPT® Code 27707

An osteotomy of the fibula, as described by CPT® Code 27707, is a surgical procedure aimed at correcting deformities or realigning the fibula, which is one of the two long bones in the lower leg. This procedure may involve the fibular shaft or the distal end of the fibula, depending on the specific deformity being addressed. The term 'osteotomy' refers to the surgical cutting of bone, and in this context, it is performed to restore proper alignment and function of the fibula. Various techniques can be employed during the osteotomy, including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy, each chosen based on the nature and location of the deformity. Prior to the surgery, the physician utilizes radiographic studies to precisely determine the locations for the bone cuts, ensuring that the procedure is tailored to achieve optimal results. The surgical approach involves making an incision over the lower leg, followed by careful dissection of the soft tissues to expose the fibula. The periosteum, a dense layer of connective tissue surrounding the bone, is elevated to facilitate access. The actual osteotomy is performed using specialized instruments such as drills, saws, or osteotomes to create the necessary bone cuts. In some cases, bone grafts may be inserted between the cut segments to promote healing and stability. To maintain the correct alignment of the bone after the osteotomy, various fixation methods, including pins, screws, or plates, may be employed. Alternatively, an external fixation device can be used if deemed appropriate. This procedure is critical for patients with fibular deformities, as it aims to restore normal anatomy and function, ultimately improving mobility and quality of life.
