Abstract
We report an extremely rare complication of early loosening of the femoral component as a result of debonding between the metal–cement interfaces presenting at 11th postoperative day. To the best of our knowledge debonding as a cause of early loosening has never been reported in literature. The postulated causes of this early debonding include either one or a combination of stem design, biomaterial and poor surgical technique.
Résumé
Nous rapportons une très rare complication consistant en un descellement précoce de la tige fémorale d’une prothèse de hanche résultant de l’absence de fixation au niveau de l’interface métal-ciment, survenu au 11 ème jour post-opératoire. Un tel cas n’a pas été retrouvé dans la littérature, du moins à notre connaissance. Les causes que l’on peut avancer pour expliquer cette désolidarisation métal-ciment sont multiparamétriques ; le design de la tige prothétique, les notions biomécaniques et l’insuffisance de la technique chirurgicale jouent un rôle.
