The beneficial role of intertrochanteric varus or valgus osteotomy in the treatment of hip @entity571 has been recognised since the 1920s. Even today, it has an important role to delay the need for hip replacement in younger @entity1 . The purpose of this study was to evaluate the long-term results of intertrochanteric varus osteotomy for @entity570 . Between 1980 and 1995, 52 hips with @entity571 underwent an intertrochanteric varus osteotomy. All @entity1 could be followed up after 17.8  years. Radiographic assessment included centre-edge (CE) angle of Wiberg and collodiaphyseal (CCD) angle. @entity572 was classified according to Crowe. @entity571 was graded according to T  nnis. @entity571 was Tonnis grade 1 in 19 hips, grade 2 in 28 and grade 3 in five. Complications were also documented. Clinical evaluation included score according to Merle d'Aubign  , Harris Hip Score and range of motion. Six of 52 @entity1 underwent total hip replacement (THR) within five  years after intertrochanteric osteotomy. In these cases, preoperative @entity571 was grade 3 in four cases and grade 2 in one case according to T  nnis. Twenty-five of 52 @entity1 underwent THR after an interval of five to ten years after intertrochanteric osteotomy. In these cases, preoperative @entity571 was grade 3 in one case and grade 2 in 24 cases according to T  nnis. Sixteen of 52 @entity1 underwent THR after an interval of ten to 15  years after intertrochanteric osteotomy. In these cases, preoperative @entity571 was grade 2 in four cases and grade 1 in 12 cases according to T  nnis. In five @entity1 the hip was functioning well after a period longer than 15  years. In all these cases @entity571 was grade 1 according to T  nnis. In 40.4% of @entity1 , THR was delayed longer than ten  years. The osteotomy performed well at a mean time of 9.7  years after the procedure (range 3-21). Intertrochanteric varus osteotomy for @entity570 should be considered in early or mild osteoarthritic changes of the hip. Good prognosis with delay of THR of more than ten  years can be expected to exceed 40%, even when indications are less than optimum.
