Hip reconstruction procedures are often conducted as a treatment option for advanced hip arthritis. The nature of the procedure can often differ based on the needs of the patient. A hip resurfacing involves placement of a cap on top of the femoral head. On the other hand, a total hip replacement involves removal of the femoral head, and replacing it with a bulb attached to a stem that is inserted into the femur. Recent innovations include the use of metal-on-metal bearings. These new models are advantageous relative to the previous polyethylene models in that they are much more durable. Furthermore, the larger bearing diameter allows for a much greater and more natural range of motion for the patient. These improvements are especially appealing to younger patients requiring hip surgery, as they are conducive to a more active lifestyle. However, these new innovations do not come without complications. Some complications with such procedures include the release of metallic debris into the body, as well as dislocation of the hip prosthetic.
Many studies have been conducted to analyze the outcomes of hip replacement procedures. One such case study was conducted on three patients who underwent total hip arthroplasty. The study was conducted by Theruvil et al. and is titled “Dislocation of Large Diameter Metal-On-Metal Bearings An Indicator of Metal Reaction?” The study was published in the Journal of Arthroplasty in 2010.
The researchers concluded that pain following implantation of a metal-on-metal prosthetic may be indicative of a reaction to the metal, and should prompt further examination. Such an investigation should take into account the serum levels of cobalt and chromium. In such a case, it is suggested that the bearing surface ought to be replaced to prevent further ion release. Failure to properly treat such cases may result in dislocation of the prosthetic.
Due to the fact that many hip replacement patients entered into the procedure unaware that metal ions could leak into their bloodstream, a number of metal-on-metal hip replacement lawsuits have been filed. In particular, lawsuits have been filed against DePuy, the manufacturer of the popular ASR hip replacement systems, for it is alleged that the company knew of these risks but failed to act.
