We reviewed the results of 13 intertrochanteric varus or valgus osteotomies performed for secondary osteoarthritis of the hip. We treated them using the modified Ueno method.
The average age of patients with varus or valgus osteotomy at operation was 40.5 years and they were followed up for an average of 68 months.
The mean postoperative J. O. A. score of patients with varus or valgus osteotomies was 84.5 points. At the latest evaluation 85% of the patients were judged as good or excellent according to the J. O. A. score.
Two patients with varus osteotomies achieved poor results. The causes of the poor results were pre-operative indications and surgical technique.
We found that valgus osteotomy with acetabuloplasty was effective even for treating severe degenerative changed arthritis (advanced stage) of the hip.
