This is a preventative surgery for hip dysplasia. A small incision is made between the hind limbs to expose the pubic bone of the pelvis. The growth plate is then cauterized to destroy the growing cells. When the growth is stopped the remaining parts of the pelvis grow, the sockets of the hip rotate over the ball of the hip resulting in a stable hip that has much less chance of developing significant arthritis. This procedure is normally done around 4 months of age at the time of the spay or neuter.
