Hip Replacement Defects

Hip Replacement Defects with Metal on Metal Hip Implants

While many people obtain hip implants to reduce their pain and achieve greater mobility, metal on metal hip implants have caused numerous problems that were often much more serious than the problem the hip implant was supposed to resolve. Theodoros & Rooth, P.C. represents clients in cases involving hip replacement defects, and we bring extensive experience to every case we handle.

Problems with metal on metal hip implants

The mechanics of any type of hip replacement involve attaching a cup to the pelvic bone and attaching a ball to the top of the femur. The ball then turns in the socket the way an individual's natural ball and socket made of bone would function.

The concept behind a metal on metal hip replacement is for a metal ball to rotate in a metal socket or cup. In theory, the concept makes sense and would provide greater durability through use of metals like chromium or cobalt. However, in practice, when the individual walks, runs, or performs other movements, the friction created between the ball and socket can result in releasing metallic particles. These microscopic metallic particles can enter the bloodstream and/or embed in tissue, creating medical complications. Some metal on metal hip implant complications include the following:

  • Intense pain in the hip, thigh and groin areas
  • Metal poisoning
  • Pseudo tumor formation
  • Intense inflammation
  • Dying tissue
  • Dislocation
  • Infection
  • Bone fractures
  • Muscle loss
  • Hip replacement misalignment or loosening
  • Trouble moving, standing or walking
  • Bodily rejection of the implant instead of acceptance into the bone

These types of complications do not occur with ceramic and plastic hip replacements. Metal rubbing against metal is a design flaw, and through lawsuits numerous patients can hold hip replacement manufacturers accountable for their adverse effects.

Another complication is the need for surgery called “revision” to remove the hip implant and replace it with a ceramic or plastic version that has fewer complications. Initially, many companies promoted the superior benefits of metal on metal hip implants ― that they would last longer and allow a more active and athletic lifestyle. Consequently, numerous patients sought replacement surgeries to take advantage of the benefits. Unfortunately, in many cases, the opposite occurred.
