DPOPreviously, triple pelvic osteotomy (TPO) had been performed in selected young dogs with hip dysplasia to reorient the acetabulum (socket) over the femoral head (ball). The procedure was fairly successful but morbidity (postoperative complication and discomfort) was high compared to other routine orthopedic procedures. Because of this, the procedure has been modified to a double pelvic osteotomy. Double pelvic osteotomy involves making two osteotomies (bone cuts) in the pelvic bones, reorienting the acetabulum over the femoral head and securing the osteotomy with a bone plate. Because a portion of the pelvis is left intact with the DPO, postoperative discomfort and complication have been minimized.

Numerous factors are considered when deciding which patients will benefit from a DPO. Patient selection criteria must be adhered to for outcomes that are consistently good to excellent. Potential patients should be less than eight months of age, have no osteoarthritis, the femoral head should be normal in size and shape and the femoral head should fall into place within the acetabulum on palpation without excessive force or angulations.
