CPT® Code 27161

Osteotomy of the femoral neck is a surgical procedure aimed at correcting deformities or abnormalities in the femoral neck, which may be short, long, or malformed. This procedure is typically indicated when conservative treatments have failed to alleviate symptoms or when structural correction is necessary to improve hip function. The surgery involves making a skin incision over the lateral aspect of the hip joint, allowing access to the femur. Once the soft tissues are carefully dissected, the femur is exposed, and the femoral head is dislocated from the acetabulum to facilitate the osteotomy. The surgeon then marks the planned osteotomy sites and performs a series of precise cuts in the femoral neck. These cuts enable the surgeon to shorten, lengthen, or reconfigure the bone as needed. Wedges created from the cut bone are strategically placed at the osteotomy sites to ensure that the proper angles are maintained in the reconfigured bone. To secure the new position and shape of the bone, internal fixation devices such as pins, screws, or wires may be utilized. After the osteotomy is completed, the femoral head is repositioned into the acetabulum, and the range of motion in the hip is assessed before the incisions are closed in layers, ensuring proper healing and recovery.
