Total hip replacement for acetabular protrusio. Challenges of a deep acetabulum


Protrusio deformity is an uncommon presentation in our environment and presents a problem of a deep acetabulum due to medial displacement of the medial wall. Management must involve reconstitution of the medial wall and therefore the biomechanics of the hip for long term survival. We present a review, discussing the pathomechanics and surgical management, with emphasis on the central role of the femoral head autograft in reconstructing the deformity.

Keywords: Protrusio deformity, acetabulum, biomechanics, pathomechanics
La déformation protrusio est une présentation rare dans notre environnement et présente un problème d’acétabulum profond dû au déplacement médial de la paroi médiale. La prise en charge doit comprendre la reconstitution de la paroi médiale et donc la biomécanique de la hanche pour une survie à long terme. Nous présentons une revue, discutant la pathomécanique et la gestion chirurgicale, en mettant l’accent sur le rôle central de l’autogreffe de la tête fémorale dans la reconstruction de la déformation.
