Abstract
The clinical and radiological follow-up of 202 patients with a cemented Hip Artrhoplasty (HA) was reviewed. The presence of periarticular heterotopic ossifications (PHO) and its gradation was compared i9n hybrid and bipolar arthroplasties. Risk factors related to the appearance of PHO, implants size, final alignment, operated side and relationship to the postoperative local and systemic complications were several of the parameter analyzed. The presence of PHO was 35,5% (degree I, 19%; degree II, 10%; degree III, 5% and degree IV, 1,5%); 9,9% symptomatic. A greater proportion of PHO was observed in males (p=0,005) greater zie stems (p=0,001) and patients with postoperative local complications (p=0,001). There were no statistical differences between patients with hybrid hip arthoplasties as compared to those with bipolar his arthroplasties. The Harris score showed differences as regards pain at 24 months follow-up between the groups whit an without PHO.
