CPT® Code 27226

The procedure described by CPT® Code 27226 involves the open treatment of fractures located in the posterior or anterior walls of the acetabulum, which is a critical component of the hip joint. The acetabulum consists of several anatomical structures, including the anterior (iliopubic) column, posterior (ilioischial) column, anterior wall, posterior wall, quadrilateral plate (medial wall), and dome. These structures collectively form the articular surface of the hip and play a vital role in stabilizing the hip joint during movement. In this surgical procedure, a surgical incision is made over the hip joint to access the fractured area. Once exposed, the surgeon performs debridement and irrigation of the hip joint to remove any debris and loose fragments that may interfere with healing. Following this, the fracture is carefully reduced, meaning the bone fragments are realigned to their normal anatomical position. Temporary fixation methods, such as pins or wires, may be employed to hold the fragments in place during the procedure. The surgeon then verifies the anatomic reduction through radiographic imaging to ensure proper alignment. For permanent stabilization, internal fixation devices are applied, which may include lag screws or a plate and screw system. In the case of lag screw fixation, the outer cortex of the bone is over-drilled to allow for the insertion of screws that secure the fracture. Alternatively, if a plate and screw fixation method is chosen, a buttress plate is positioned along the rim of the acetabulum at the fracture site and secured with lag screws. Additionally, if necessary, separately reportable bone grafts may be utilized to further stabilize the fracture fragments, enhancing the overall success of the surgical intervention.
