Abstract
Patients suffering from post traumatic osteoarthritis of the acetabulum often require a total hip arthroplasty at a relatively young age Longterm data outcome studies for this population are lacking We report on the longterm outcome of 20 acetabular fractures in 20 patients treated with impaction bone grafting and a cemented cup after a mean followup of 18 years range 12–26 yearsThe group consisted of 14 males 70 and six females 30 with an average age of 533 years range 35–75 years at time of surgery No patients were lost to followup Four patients died and three patients underwent a revision at review 13 patients were still living with their implant in situ Survivorship analysis was performed at 20 years followup for three endpointsSurvival rate with endpoint revision for any reason at 20 years postoperative was 747 95 confidence interval CI 40–91 800 95 CI 41–95 for endpoint aseptic loosening and 639 95 CI 32–84 for endpoint radiographic failure Three acetabular components were revised at 145 153 and 167 years postoperative Two cups failed for aseptic loosening and one cup failed due to septic loosening The average postoperative Harris hip score was 82 range 56–100
