Total Hip Arthroplasty in High Dislocated and Severely Dysplastic Septic Hip Sequelae

Abstract 

The authors analyzed a consecutive series of 20 total hip arthroplasties performed using a cementless conical stem with shortening osteotomy combined with greater trochanter transfer in cases with a highly dislocated hip secondary to sequelae of a septic hip in childhood. Mean patient age was 47.3 years and the mean follow-up period was 3.4 years. An acetabular metal cup was inserted in 5 cases, and only a liner was inserted after cementing in 15 cases. Mean Harris hip score improved from 42.4 preoperatively to 84.2 at final follow-up. Mean leg lengthening was 36.5 mm, and time to greater trochanter union was 3.72 months. No complete radiolucent line of thickness >2 mm was observed in any case. These surgical methods produced satisfactory clinical and radiological results.
