Product ASR ACETABULAR IMPLANT 54, DEPUY ASR ACETABULAR CUP SYSTEM, DePuy Articular Surface Replacement (ASR) Hip Prosthesis System.

The DePuy ASR Acetabular Cup System is comprised of a one-piece metal acetabular cup, a unipolar femoral head, and a taper sleeve adapter. The acetabular component is designed as a cobalt-chrome molybdenum (CoCrMo) alloy one-piece cup with Porocoat¿ porous coating and is available in outer diameter sizes 44mm through 62mm in two-millimeter increments.

The outer surface of the cup has a porous coating with the addition of a hydroxyapatite (H-A) coating. There are no separate liner components to this system, as the liners are integral to the one-piece acetabular cups.

The DePuy ASR TM Acetabular Cup System is indicated for use in total hip replacement procedures for patients suffering severe pain and disability due to structural damage in the hip joint from rheumatoid arthritis, osteoarthritis, post-traumatic arthritis, collagen disorders, avascular necrosis, and nonunion of femoral fractures. Use of the prosthesis is also indicated for patients with congenital hip dysplasia, slipped capital femoral epiphysis and disability due to previous fusion, where bone stock is inadequate for other reconstruction techniques.
