Total hip arthroplasty after childhood septic hip in patients younger than 25 years of age.

Childhood septic hip should usually be treated immediately by arthrotomy and antibiotic. Even if treated correctly, the affected hip may become osteoarthritic and functionally disabling. Usually the literature is not in favor of total hip arthroplasty in young patients, and the reports are on patients older than 32 years of age. We present here a unique group of very young patients with early coxarthrosis caused by septic hip in childhood, with an average age of 19.14 years (range, 14-25) at the time of the arthroplasty. The Harris hip score improved from a preoperative mean of 58.43 to a postoperative mean of 94.14. The follow-up period ranged between 2 and 24 years, with an average of 8.14 years. We conclude that total hip arthroplasty in young people with early coxarthrosis caused by septic hip in childhood provides good functional results.
