Miss the Filing Deadline for Your DePuy ASR Hip Case? There May Still Be Hope

Despite the fact that the August, 2010 recall of the DePuy ASR metal-on-metal hip implant caused a significant stir among the medical community, thousands of recipients of the metal implant remained unaware of recall and subsequent warnings. Due to the initial FDA notice which was issued July 17, 2010 and the recall of the implant on August 24, 2010, all those who live in a state which operates under a two-year statute of limitations may have already lost their right to file suit against DePuy and Johnson and Johnson. Over half of the states do operate under that two year SOL, while others extend that time limit to three, four, six or even ten years. A handful of states have a one-year statute of limitations.  If you are the recipient of a DePuy metal hip implant it’s important that you determine your state’s statute of limitations for defective medical products even if you are currently having no problems with your implant.

Although DePuy originally set their metal implant’s failure rate at approximately 5%, they increased that number to 12% at the time of the 2010 recall. Independent studies place the likelihood of a DePuy ASR implant failure much higher—50% at five years following implant surgery and 80% at eight years following implant surgery. Statistically speaking, even those patients who have not yet experienced failure of their hip implant or adverse health effects from metal toxicity will do so in the very near future. It is extremely important that all DePuy ASR implant recipients at least be aware of their options prior to the date the statute of limitations will run.

The DePuy ASR Metal-on-Metal Hip Implant: A Scientific Analysis of its Problems

The last ten years have seen surgical replacement of hip joints with an artificial prosthesis increase significantly. The main reason for this surge in hip replacement surgeries is our aging population. With people living longer, more active lives, degenerating hip joints can put a halt to that activity. From 1997 through 2004, the number of hip replacement surgeries increased nearly 50% and if the trend continues it is estimated that the annual number of hip replacements in the United States will reach 600,000 by 2015.

Factors in Hip Replacement Surgery

Primary reasons for patients undergoing hip replacement surgery include chronic pain, impairment of daily functions and severe arthritis in the hip joint. The most common type of arthritis leading to total hip replacement is osteoarthritis and is generally seen with aging or trauma to the hip joint. In some instances necrosis of the hip can be present, usually caused by a fracture, alcoholism, lupus, or taking steroid drugs such as prednisone. Patients may experience progressively worsening chronic pain which prohibits them from walking, climbing stairs or even getting up from a sitting position.

Types of Hip Implants

There are many different types of hip replacement implant including the metal-on metal, metal-on-polyethylene and metal-on-ceramic as well as the implants which are 100% ceramic or polyethylene. Other than the materials the implant is constructed with, the only other major difference is in how the implant is affixed—it can be cemented to the bone or attached in such a manner that it grows into the patient’s remaining bone. The idea behind the cobalt and chromium metal-on-metal hip implant was to create an implant which would not have to be re-done for fifteen to twenty years—unlike the ceramic and polyethylene hip implants which last approximately 8-12 years.
