A stainless steel plate was designed for use on the dorsal rim of the acetabulum of the dog. The surgical procedure, using this plate, is easier and less time consuming than previous techniques, because the plate is easier to contour to the dorsal rim of the acetabulum. The use of this plate, compared with other types of plates, has resulted in more accurate anatomic reduction after fixation. No long-term complications caused by the plate or screws have been identified. Follow-up examinations have revealed that the functional use of the limb is as good as with other types of plates.
