Abstract

The Adaptiva custom-made stem is a hip stem anchored by fit and fill press-fit into the proximal femur and manufacture is based on computed tomography (CT) scanning. Its concept was developed for primary and revision hip arthroplasty in younger patients in our clinic. We present the advantages and the disadvantages of the system. After 66 months 98.9% of the patients are satisfied with the surgical outcome; 86% attained very good and 9% good results according to the Merle d’Aubigné score. Despite good clinical results and a high satisfaction rate, we stopped using this stem because we do not see any advantages in comparison with standard implants and feel that the price for a custom-made stem for primary hip arthroplasty is too high.

Résumé

La tige prothétique Adaptiva est une tige sur mesure à ancrage sans ciment par ajustage à partir des données de scanner. Ce concept a été développé dans notre Centre pour les prothèses primaires et de révision chez les sujets jeunes. A 66 mois , 98,9 % des patients sont satisfaits de l’évolution, avec selon la cotation de Merle d’Aubigné 86% de très bons et 9% de bons résultats. Malgré les bons résultats cliniques et le haut degré de satisfaction nous avons arrêté la fabrication de cette tige car nous ne voyons pas d’avantage en comparaison d’implants standards et le prix d’une prothèse sur mesure pour une arthroplastie primaire est trop élevé.
