Summary

Between May 1980 and May 1987, intertrochanteric osteotomy was performed on 43 hips of 37 dogs (6 bilateral procedures) with early-stage hip dysplasia, with the objectives of improving hip biomechanics and reducing discomfort. Clinical evaluation consisted of: questionnaire, and/or orthopedic examination, and/or report from owner(s) via telephone. At least 1 form of evaluation was conducted for 42 of 43 hips (98%). On the basis of orthopedic examination findings, 27 of 33 hips (84%) were functionally good or normal at postoperative month 15 (on average). On the basis of owner report, 19 of 28 hips (68%) were functionally good or normal at postoperative month 11 (on average). On the basis of questionnaire data, 17 of 24 hips (70%) were functionally good or normal at postoperative year 1. Before surgery, only 11 of 37 hips (30%) had been evaluated as functionally good or normal. Of 36 owners, 33 (91.6%) reported that they would have the procedure performed again if the circumstances were the same. From the good to excellent clinical results, we concluded that intertrochanteric osteotomy is a beneficial treatment for dogs with early-stage hip dysplasia.
