TPO (Triple pelvic osteotomy) surgery for hip dysplasia in dogs.

Hip dysplasia is a common cause of lameness in young large & giant breed dogs. If detected early before the closure of the growth plates corrective triple pelvic osteotomy TPO or Juvenile Pubic Symphysiodesis JPS surgery may be performed to improve the coverage of the femoral head by the acetabulum. This is usually done by a triple pelvic osteotomy (TPO) which for best results should be performed at 5-9 months of age and must be done before the onset of DJD or significant articular cartilage damage. The pelvis is cut in three places (osteotomy) and a plate applied to the ilial osteotomy site to rotate the acetabulum between 20-40 degrees as needed. Some improvement is seen immediately in the post op radiographs however significant improvement is usually seen over the following 6 months as remodelling & growth  occurs.

Triple pelvic osteotomy  surgery

Bilateral Triple pelvic osteotomy with good acetabular coverage at a four year follow up radiograph. No evidence of DJD is visible in either hip.

If early corrective surgery is not performed, particularly in large breed dogs, which may also be overweight development of severe arthritis is likely. A femoral head & neck osteotomy (FHO) may have to  performed to reduce the pain. A total hip replacement (THR) may also be considered in large dogs.
