Abstract
in English, French

We studied 178 patients undergoing total hip arthroplasty (66 men and 112 women) retrospectively, with regard to the incidence and severity of heterotopic ossification and the significance of postoperative prophylaxis with non-steroid anti-inflammatory drugs. The overall incidence of heterotopic ossification was 32% 1 year after surgery. The factors increasing the incidence were male gender, previous arthroplasty of the contralateral hip joint, previous surgery on the hip, absence of preoperative treatment with non-steroidal anti-inflammatory drugs and an operating time of more than 100 min. The incidence of heterotopic ossification was lower in the patients of O blood group.

Nous avons étudié la fréquence et la sévérité d'ossification hétérotopique dans 178 cas d'arthroplastie totale de la hanche avec une prophylaxie postopératoire par AINS. Une année après la chirurgie la fréquence totale était de 32%. Les facteurs qui augmentent le risque étaient le sexe masculin, une arthroplastie de la hanche contrelaterale, des antécédents chirurgicaux sur hanche, l'absence de traitement préopératoire par AINS et une durée opératoire de plus de 100 min. La fréquence d'ossification hétérotopique était inférieure chez les patients du groupe sanguin 0.
