CPT® Code 27450

An osteotomy of the femur, specifically targeting the shaft or supracondylar region, is a surgical procedure aimed at correcting bone deformities or realigning the femur. This procedure is essential for addressing various orthopedic conditions that may affect the alignment and function of the leg. The term "osteotomy" refers to the surgical cutting of bone, and in this context, it is performed on the femur, which is the long bone in the thigh. The specific location of the osteotomy, whether at the shaft or the supracondylar area, is determined based on the nature and location of the deformity being treated. Different types of osteotomies can be employed, including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy, each serving a unique purpose depending on the clinical scenario. Prior to the surgical intervention, the physician utilizes radiographic studies to accurately assess the bone structure and determine the optimal site for the osteotomy. This preoperative planning is crucial for achieving the desired surgical outcome. During the procedure, an incision is made over the targeted area of the femur, allowing for the dissection of soft tissues to expose the bone. The periosteum, a dense layer of connective tissue surrounding the bone, is elevated to facilitate access. The surgeon then employs tools such as a drill, saw, or osteotome to create a precise cut in the bone according to the predetermined configuration. In some cases, bone grafts may be inserted between the cut segments to promote healing and stability. To ensure that the bone segments remain properly aligned during the healing process, various fixation methods may be utilized, including pins, screws, or plates. Alternatively, an external fixation device may be applied if deemed necessary. It is important to note that if the procedure is performed without any fixation, a different CPT® code (CPT® 27448) should be used, whereas CPT® 27450 is designated for cases where a fixation device is employed.
