[Experiences with the Pauwels osteotomy and its improvement in the last 20 years].

Intertrochanteric osteotomies (Pauwels) were performed in 203 hips. Their average age at operation was 41 years (range 15 to 66 years). Average follow-up was 16 years and 5 months. 78 of 203 hips had been undergone varus osteotomies (P1) and valgus osteotomies (P2) were in 125 hips. All the hips were evaluated clinically and radiologically. 140 hips (69%) had no pain. 132 hips (65%) showed no arthritic changes. In summary, we feel that Pauwels' osteotomy is a reliable method in the treatment of the young and middle aged patient.
