CPT® Code 27259

Open treatment of spontaneous hip dislocation (developmental, including congenital or pathological), replacement of femoral head in acetabulum (including tenotomy, etc); with femoral shaft shortening

The CPT® Code 27259 refers to the open treatment of spontaneous hip dislocation, which can occur due to developmental dysplasia of the hip (DDH). This condition may arise from congenital malformations of the hip joint or develop during growth, impacting the osseous structures, joint capsule, and surrounding soft tissues. The procedure involves a comprehensive approach to address the dislocation, which includes the replacement of the femoral head into the acetabulum, along with the shortening of the femoral shaft. The treatment typically necessitates an adductor tenotomy, which is a surgical procedure that involves cutting the adductor tendon to facilitate the reduction of the dislocated hip. The surgical intervention begins with a skin incision made in the medial aspect of the groin, allowing access to the adductor tendon and other soft tissue structures that may need to be released to achieve proper alignment and reduction of the dislocation. Following the repositioning of the femoral head, the procedure is further complicated by the need for an osteotomy, where the femoral shaft is intentionally shortened to improve the stability and function of the hip joint. This complex surgical procedure is critical for restoring normal hip function and preventing future dislocations, ensuring that the hip is maintained in an optimal position post-surgery, often with the application of a splint or hip spica cast to support recovery.
