Video of DePuy ASR Hip Failure Symptoms

If you have a failed DePuy ASR Hip Implant, you probably already know this, but for patients with the implant and no symptoms yet, this information and video can help you know what to look for.

DePuy Hip Implant Failures- Video of symptoms

Some of the symptoms of the ASR hip failure are pain or trouble walking.  Many patients with loose ASR hips report having “lift off pain,” or sharp groin pain that lasts a few minutes after you get up from a chair.

How to tell if you have one of the failed DePuy hips

Since the DePuy ASR hip recall 2 weeks ago, a lot of people are wondering:  “How do I find out if I have one of the failed hips?”  It’s a good question, but there’s no clear answer.

How the recall works: Usually when a manufacturer issues a recall, they include a list of batch numbers or serial numbers to identify specific products.  That way you can check and see if the recall affects you.  But the DePuy ASR hip recall doesn’t break it down into specific product batches.  The recall is for ALL of the affected hip replacements. That’s almost 100,000 hips replacements!
DePuy believes that 12%-13% of all of the implanted hips are failing in the first 5 years, but that number could be much higher.  And even a 12% chance of failure is high enough for anyone with one of these implants to be concerned.
So what do you do now?  Basically you’re in limbo.  If your DePuy ASR hip hasn’t failed yet, you will likely end up waiting to see if it does fail.  Either way, you should go see your orthopedic surgeon soon just to get checked out.
Some of the symptoms of the ASR hip failure are pain or trouble walking.  Many patients with loose ASR hips report having “lift off pain,” or sharp groin pain that lasts a few minutes after you get up from a chair.  If you’re having any symptoms at all, then it’s definitely time to see your orthopedic doctor right away.
You should also talk to an experienced medical product liability attorney immediately. That’s because if you do need another surgery to replace the failed DePuy ASR hip, it’s important to preserve evidence from the procedure.

Interesting Study from Mayo Clinic about metal on metal hip failures.

The research abstract below is excellent background information for anyone who may have experienced these types of hip failure issues.

Failed metal-on-metal hip arthroplasties: a spectrum of clinical presentations and operative findings.
Browne JA, Bechtold CD, Berry DJ, Hanssen AD, Lewallen DG.

Mayo Clinic, 200 First Street SW, Rochester, MN 55905, USA.

Abstract
BACKGROUND: A number of recent reports have described novel failure mechanisms of metal-on-metal bearings in total and resurfacing hip arthroplasty. Hip arthroplasties with metal-on-metal articulations are also subject to the traditional methods of failure seen with different bearing couples. There is currently little information in the literature to help guide timely clinical evaluation and management of these patients.

QUESTIONS/PURPOSES: We therefore describe the (1) clinical presentations; (2) reasons for failure; (3) operative findings; and (4) histologic findings in patients with failed metal-on-metal hip arthroplasties.

METHODS: We retrospectively identified all 37 patients (37 hips) with metal on metal total hip or resurfacing arthroplasties who underwent revision over the past 3 years at our institution. Relevant clinical, radiographic, laboratory, intraoperative, and histopathologic findings were analyzed for all patients.

RESULTS: Of the 37 patients, 10 were revised for presumed hypersensitivity specific to the metal-on-metal articulation. This group included eight patients with tissue histology confirming chronic inflammation with lymphocytic infiltration, eight with aseptic loosening of a monoblock screwless uncemented acetabular component, two with iliopsoas impingement associated with a large-diameter femoral head, and three with femoral neck fracture after resurfacing arthroplasty; the remainder of the patients were revised for infection, instability, component malposition, and periprosthetic fracture.

CONCLUSIONS: Increased awareness of the modes of failure will bring to light the potential complications particular to metal-on-metal articulations while placing these complications into the context of failures associated with all hip arthroplasties. This novel clinical information should be valuable for the practicing surgeon faced with this patient population.

LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.
