The TPO is a procedure utilized to correct the subluxation seen with hip dysplasia. By definition, 3 cuts are made in the animal's pelvis which allows for rotation of the hemipelvis. Then, by applying a plate with a predetermined angle and screws to the pelvis, the new angle for the joint is maintained.
Age alone is not a factor in determining the candidates for this procedure. The most important factors are the depth of the acetabulum [socket] and the absence of significant arthritic changes. Ideally, the best candidate is the 6 month old dog with minor subluxation of his/her hips and no degenerative changes.
