ORIF prevented need for later THA in acetabular fracture patients

Long-term follow-up showed that open reduction and internal fixation successfully treated displaced acetabular fractures in patients without the need for subsequent total hip arthroplasty, according to this study.
Researchers analyzed 816 acetabular fractures treated with open reduction and internal fixation over a 26-year period. Cumulative 2 to 20 year Kaplan-Meier survivorship analyses of the hip — including best and worst case scenarios — were performed with total hip arthroplasty or hip arthrodesis as the end point. To identify negative predictors, researchers performed univariate and multivariate Cox regression analyses constructed a nomogram that predicted an individual’s need for early hip arthroplasty.
At 20-year follow-up, the cumulative hip survivorship available was 79%. The resulted showed cumulative 20-year survivorship was 86% in best case scenarios and 52% in worst case scenarios. Researchers found that nonanatomical fracture reduction, anterior hip dislocation, patient age greater than 40 years, postoperative acetabular roof incongruence and posterior acetabular wall involvement were significant independent negative predictors. Additionallty, acetabular impaction, femoral head cartilage lesion, initial articular surface displacement 20 mm or greater and utilization of the extended iliofemoral approach were also significant independent negative predictors.
