Resurfacing arthroplasty of the hip is currently enjoying a resurgence in

popularity. There are many reasons why resurfacing may be indicated, but one

is that the absence of proximal femoral reaming at surgery may reduce the

occurrence of heterotopic ossification (HO) after surgery. The objective of

this study was to compare the prevalence of postoperative HO for patients

undergoing two different types of hip surgery, resurfacing arthroplasty or

total hip replacement. Data were gathered from 43 consecutive patients

undergoing metal on metal hip resurfacing (MoM-R) and 37 consecutive

patients undergoing metal on metal total hip replacement (MoM-THR) with a

minimum of six months' follow up. The r classification was used to

grade HO from postoperative radiographs1. We found that, when undergoing

MoM-R, women had a lower chance of developing HO than men (p=0.04). In

addition, women who received a MoM-R had a reduced incidence of developing

HO than women who received a MoM-THR (p=0.04). There were no differences in

the incidence of postoperative HO between men undergoing either MoM-R or

MoM-THR. It can be concluded from this study that resurfacing does reduce

the incidence of HO in women and that care must be taken when selecting

women to undergo total hip replacement in preference to hip resurfacing.

This study has highlighted the need to inform patients of HO as a common

complication when consenting for hip arthroplasty, and has established an

18% rate of postoperative HO for hip resurfacing arthroplasty.
