subject: What Are Some Of The Safest Hip Replacements To Use? [print this page] Most patients undergoing any type of surgery have high standards for the procedures that are performed and the instruments that are used. These same patients also expect that these techniques and devices have undergone thorough research, testing, and have produced high levels of safety. Due to the DePuy recall, patients are questioning the safety of medical procedures, particularly hip implant surgeries. Many of these hip replacement surgeries are said by some orthopedists to be unnecessary. Patients having hip replacement surgery should research the different types of hip implants that are available and make an informed decision as to which will be best suited for them. Here are the four most common types:
" Metal-on-plastic
In this type of hip implant, the femoral head is constructed of metal with the liner composed of standard polyethylene plastic. This type is not well suited for patients who are younger and more active since standard polyethylene liners are highly susceptible to erosion. These types of patients will often need corrective surgery within seven to ten years of the original procedure. Best suited for these types of implants are patients that are elderly and/or with lower levels of daily activity. These hip implant systems are recommended for patients who are elderly and/or who have lower levels of daily physical activity.
" Metal-on-highly crosslinked polyethylene
These types of systems are fundamentally similar to metal-on-plastic system, but differ in the fact that crosslinking the polyethylene creates a more durable and stable implant. This type of system has replaced the standard metal-on-plastic system and is ideally suited for the younger, more physically active types of patients.
" Metal-on-metal
Although these are the types that are currently undergoing the DePuy hip replacement recall, not all metal-on-metal implants are manufactured by DePuy. Other manufacturers have not been reported to have the same failure rates. Metal-on-metal hip implants are associated with increased stability and longevity. However, those with any type of sensitivity or allergy to metal should avoid these types of implants. The particles released due to friction of the implant components circulate in the bloodstream, resulting in an allergic reaction and nerve damage.
" Metal-on-ceramic
Metal-on-ceramic hip replacements are more resistant to erosion, as opposed to the other types. With regards to wear and tear, metal-on-ceramic outperforms both metal and plastic types of hip implants. Although this type is less likely to cause an allergic response, it is more susceptible to breaks and fractures.
The DePuy hip recall has questioned the safety of hip implants. Many have learned that filing a DePuy Asr lawsuit in the wake of the recall would be the best option so far. However, patients should educate themselves with regards to the types of implants that are available. Patients should also talk with their surgeon to figure out with implant would best accommodate their level of physical activity, age, health, current health of their bones, and other factors.
