Abstract
Sixty consecutive patients (60 hips) were allocated in two matched-pair groups. Patients were matched for age, gender, body mass index, level of activity, and bone stock. Both groups received an uncemented total hip arthroplasty with a modular press-fit cup and an alumina femoral head. In the first group, an acetabular liner made of polyethylene was used; in the second group, an alumina liner. Both groups were followed for a minimum of 5 years. No hip required revision, and there was no radiographic evidence of aseptic loosening in either group. Mean Harris hip score was 94.7 (87.1–99) points in the polyethylene group and 93 (88.5–100) points in the alumina group.
Résumé
Soixante malades consécutifs (60 hanches) ont été répartis dans deux groupes appairés pour l'âge, le genre, l'index de masse corporelle,le niveau d'activité, et le stock osseux. Les deux groupes ont reçu une arthroplastie totale de la hanche non-cimentée avec une cupule acétabulaire modulaire et une tête fémorale en alumine. Dans le premier groupe un insert acétabulaire en polyéthylène a été utilisé, dans le deuxième groupe un insert d'alumine. Les deux groupes ont été suivis avec un minimum de 5 années. Aucune hanche n'a nécessité de révision, et il n'y avait aucun signe radiographique de descellement aseptique dans l'un ou l'autre groupe. Le score moyen de Harris était 94.7 (87.1–99) points dans le groupe polyéthylène, et 93 (88.5–100) points dans le groupe alumine.
