The Frank Stinchfield Award: Dislocation in Revision THA: Do Large Heads (36 and 40 mm) Result in Reduced Dislocation Rates in a Randomized Clinical Trial?

Abstract: Background Dislocation after revision THA is a common complication. Large heads have the potential to decrease dislocation rate, but it is unclear whether they do so in revision THA.Questions/purposes We therefore determined whether a large femoral head (36 and 40 mm) resulted in a decreased dislocation rate compared to a standard head (32 mm). Methods We randomized 184 patients undergoing revision THA to receive either a 32-mm head (92 patients) or 36-and 40-mm head (92 patients) and stratified patients by su… Show more

“…These are the only other studies we have found previously reporting on a large-scale multivariate analysis. Other studies have also shown femoral head size to be a factor in the stability of the revision THA [1,3,8,20]. Cogan et al [5] evaluated patients undergoing revision THA through an anterior approach and found BMI was the only risk factor for dislocation in their patient population.…”

“…In addition, the sizes of the removed and revision acetabular components, femoral heads, and retained femoral components are not available. The size of the femoral head component could be especially useful information for the risk of dislocation, because large femoral head components (36-40 mm) have been shown in two studies to reduce the risk of dislocation after revision THA [17,21]. Third, the acetabular revision admission was excluded from the analysis of dislocation, deep infection, and rerevision.…”
