The purpose of this study is to demonstrate a new surgical approach for the selective denervation of the sensitive fibers of the acetabular periosteum, for the treatment of hip dysplasia in dogs, conducted in 189 joints.The surgical approach of the cranial and dorso-lateral regions of the acetabular joint in dogs, by moon-shaped incision of approximately 3cm in extension, starting from the greater trocanter of the femur, in direction of the ileum body. After dorsal opening of the middle gluteal muscle, the insertion of the deep gluteal muscle is inserted for the access to the mentioned regions. With the help of a curette, the periosteum of the cranial and dorso-lateral acetabular margin was removed until the bone cortex was exposed, in all patients. In all animals, the approach was possible, both in the cranial as well as in the caudal faces for the access and curettage of the acetabulum, with the technique described, with a skin incision of about 3.2cm. The curettage of the cranial portion of the acetabulum was, in all cases, realized without the visualization of the bone, but of easy achievement and without intercurrences of nervous or muscular injuries. In all the approaches, it was possible to visualize the articular capsule of the coxo-femoral joint, and in none of the animals, this structure was incised for a technique mistake. The surgical approach described in the present study is feasible for this kind of surgical procedure in dogs, promoting adequate access, with minimal invasion and with no complications of any nature.
