An In-depth Review on Metal-n-Metal Hip Implant
Hip replacement is one of the regularly performed orthopedic procedures.It engages substitution of the hip joint with a prosthetic ball-and-socket joint.It is carried out to address a persistently painful and stiff hip, a fracture that did not heal or joint degeneration. During hip replacement, the femoral head, neck and part of the shaft are removed and replaced with a prosthetic implant.Implants are available in the market and each are made out of different materials. An example of this is the metal-on-metal implant which utilizes cobalt-chromium alloy from the head down to the shaft. The DePuy Orthopedics has released this kind of implant but has issued a voluntary recall on the product after the rising criticism about DePuy hip recall symptoms.
What then is a metal-on-metal hip implant?
Metal-on-metal (MoM) hip implants consist of a ball, a stem and a shell, all made of metal. It is more suitable for younger and physically active individuals because the durability of the metal implant can last for years. MoM implants have larger femoral heads that help avoid dislocation and allow greater range-of-motion.Based on the record of Nationwide Implant Sample database, there are about 39,200 MoM hip replacements performed in the year 2005-2006. Evaluation and test for compatibility of metal-on-metal implants are done by FDA through their 510(k) program.
One concern on this implant is the long-term frictional release of cobalt or chromium ions from the joint despite its low wear rates. Overtime, the amount of metal ions in the body will increase and may eventually lead to metallosis.According to a case report of the Journal of Bone and Joint Surgery, 2 patients complained of adverse effects after receiving MoM total hip replacements. Cobalt toxicity manifestations following the procedure were observed on these patients.
There is no truth behind the concept of a perfect hip implant. The patient should therefore submit himself to a comprehensive assessment and evaluation by a health care professional and talk about what hip device suits his condition well. Advantages and disadvantages alike are present in a metal-on-metal hip implant.MoM implants have larger femoral heads that help avoid dislocation and allow greater range-of-motion.Based on the record of Nationwide Implant Sample database, there are about 39,200 MoM hip replacements performed in the year 2005-2006. Evaluation and test for compatibility of metal-on-metal implants are done by FDA through their 510(k) program.
One concern on this implant is the long-term frictional release of cobalt or chromium ions from the joint despite its low wear rates. What is essential is, you seek help from a health care professional and discuss with him the hip implant that is fitting to your condition. The likelihood of developing untoward effects like a DePuy hip recall will lessen if not totally eradicated.
