ASR FEMORAL IMPLANT SIZE 53, DEPUY ASR RESURFACING FEMORAL HEADS, DePuy Articular Surface Replacement (ASR) Hip Prosthesis System. The DePuy ASR Resurfacing Femoral Heads are designed for use in hemi-arthroplasty applications to replace the articular surface of the femoral head. The implants consist of a one-piece, cobalt-chromium-molybdenum (Co-Cr-Mo) metal femoral head with a short stem used as a cential guide pin. The implants range in sizes 39mm through 63mm to suit varying patient anatomy. The femoral resurfacing heads have a polished exterior surface and an internal cavity designed for use with bone cement for fixation to the patient's prepared femoral head. The implant allows for the minimal removal of bone from the femoral head, replacing the bone with a metal shell (cap). Articulation occurs between the polished femoral resurfacing implant and the patient's natural acetabulum. Prescription Use, Sterile. The DePuy ASR Resurfacing Femoral Heads are intended for cemented use in partial hip replacement procedures (hemi-arthroplasty). Indications are for patients suffering severe pain and disability due to osteoarthritis, rheumatoid arthritis, congenital hip dysplasia, post-traumatic arthritis, avascular necrosis, or slipped capital femoral epiphysis. Additional indications include other abnormalities where major pathology affects the femoral head; where the acetabular cavity is normal and not deformed or weakened; and where acetabular replacement is either not required or not desirable.

For patients who are symptomatic or implanted with a cup angle greater than 45 degrees, particulary where a small component has been implanted.: " Consider measuring cobalt and chromium ion levels in whle blood and/or performing cross sectional imaging including MRI or ultrasound scans. " If metal ion levels in whole blood are elevated above 7 parts per billion (ppb) for either metal ion, a second test should be performed three months after the first in order to identify patients who require closer surveillance, which may include cross sectional imaging " If MRI or ultrasound scan reveals soft tissue reactions, fluid collections or tissue masses, then revision surgery should be considered.
