Abstract:

Articles in the literature about hydroxyapatite-coated hip prostheses show both the clinical and radiologlcal results are extremely satisfactory in the short and medium term. They bear out the reliability, constancy, and durability of bio-active fixation. As in the case of cemented prostheses, results are tempered by the emergence of complications linked with the particles produced by polyethylene wear, a particular cause of osteolysis in the femur or acetabulum. The ABG II HA hip prosthesis was designed with the aim of reducing this type of complication while maintaining the principle of bio-active fixation. Implantation of the system is subject to certain requirements; in particular, a preoperative radiologic assessment is required and the surgical technique must be strictly followed to optimize the biomechanical functioning of the implanted hip.
