Triple Pelvic OsteotomyHip dysplasia is a developmental bone disease of dogs causing the hip joints to be loose. Both hips of rapidly growing large breed dogs are affected. A loose hip in a young dog means the ball (femoral head) easily
slides out of the socket (acetabulum). Looseness leads to inflammation and painful limping and bunny hopping. |
The ball must stay in the socket to create a deeper socket as the dog grows. A
shallow socket allows the ball to slide out more. The cartilage covering the bone surfaces and the acetabular rim are damaged. The ligament that
connects the ball to the socket's center is stretched. Inflammation of the joint lining causes thickening. An Ortolani test and PennHip radiographs under
anesthesia prior to surgery help to determine the severity of the hip looseness. Radiographs evaluate the shallow acetabulum, flattening of the
femoral head, arthritic changes, and the degree of looseness of the joint. If arthritic changes are present, it may be too late to perform Triple Pelvic
Osteotomy (TPO) surgery. TPO surgery helps stabilize the shallow hip of dogs between the ages of 4-15 months. The surgery involves rotating the pelvic bone containing the socket to allow more coverage of the ball.
Improved placement of the ball in the socket prevents the looseness and pain in the hip. The rotated pelvic bone is held in its new position with a bent
bone plate and screws. Surgery can be performed on both hips but preferably not on the same day. Possible complications include pain, infection, narrowed pelvic canal, persistent joint instability, and implant
failure. TPO surgery helps the hip joint function more normally and slow arthritic changes.|
