title: Reattachment of the greater trochanter using the Dall-Miles cable grip system in revision hip arthroplasty.
abstract: Clinical and radiographic results of trochanteric osteotomy after revision hip arthroplasty in 62 hips were reviewed. The osteotomized fragment had been reattached using the Dall-Miles cable grip system in each hip. The patients' average age at operation was 64.4 years (range, 40-86 years). The average duration of follow-up was 30.0 months (range. 12-60 months). Trochanteric nonunion was found in 19 hips (30.6%). Trochanteric nonunion developed in 14 (38.9%) of 36 hips with each cable attached around the medial cortex bone, in 2 (16.7%) of 12 hips with each cable passed in a drill hole, and in 3 (21.4%) of 14 hips with one cable passed through a hole and the other attached around the medial cortex. Fragmentation developed in 18 hips (29.0%). In 3 of these 18, the fragments had migrated close to the acetabular component. Cable breakage was seen in 4 hips (6.5%), and bone absorption around the cable in the medial cortex was seen in 17 hips (27.4%). There were 16 hips (25.8%) that presented symptoms at the greater trochanter, including spontaneous pain and tenderness. When the Dall Miles cable grip device is used for reattachment of the greater trochanter, attention should be paid to the condition of the trochanteric bed, the tension of the abductor muscles, and to the placement of the cables and the H-shaped grip.
