Cemented sockets with roof graft have high 10-year survivorship for patients with acetabular dysplasia
Researchers in the Netherlands found cemented sockets with a roof graft to have high 10-year survivorship in cases of severe acetabular dysplasia.
According to the study abstract, the research team performed a retrospective review of 74 hips in 62 patients with a mean age of 45 years who underwent cemented total hip arthroplasty with an acetabular roof graft. They then determined cases of revision and radiographic failure while also obtaining clinical scores, matching this data to that of a control group. The researchers used Kaplan-Meier analysis to determine survivorship with a minimum 5-year follow-up.
At a mean follow-up of 10.4 years, the researchers wrote in the abstract, survivorship for all-cause revision was 98%. The team noted two hips underwent revision for aseptic acetabular loosening, with one undergoing revision for polyethylene wear.
“All grafts incorporated and no additional radiographic loosenings were seen,” the authors wrote. “Patients with grafting had higher Oxford scores compared with the control group, but other scores were equal.”
The authors concluded that in patients with dysplasia — a cohort that tends to be young — the bone stock-restoring technique appears to be a viable solution.
