CPT® Code 27140

The procedure described by CPT® Code 27140 refers to an osteotomy and transfer of the greater trochanter of the femur, which is classified as a separate procedure. This surgical intervention is primarily aimed at enhancing the function of the hip's abductor muscles and ensuring appropriate soft tissue tension, particularly in patients who have experienced prior injuries or surgical interventions involving the hip joint. The greater trochanter is a prominent bony structure located on the femur, serving as an important attachment point for muscles that facilitate hip movement. The procedure involves making a skin incision over the lateral side of the hip, followed by careful dissection of the soft tissues to expose the greater trochanter. Once exposed, the surgeon marks the site for the osteotomy and performs a series of precise cuts around the greater trochanter to completely detach it from the femur. After the osteotomy, the greater trochanter is repositioned to optimize its function and is secured in place using various fixation methods, such as wires, cables, or a plate and screw system. Finally, the surgeon checks the hip's range of motion to ensure proper alignment and function before closing the incisions in layers to promote healing.
