Most patients undergoing any type of surgery have high standards for the procedures that are performed and the instruments that are used. All these patients assume that the procedures and devices utilized have been thoroughly researched, tested, and given a high standard of safety. However, the recent DePuy hip recall has started to put doubt in the minds of patients everywhere not only with hip replacements, but with medical procedures in general. Therefore, it is important that patients undergoing hip replacement surgery should educate themselves as to the types of hip implant systems that are available and compare each one in order to chose which one is best suited for them. The following are the four most common types:
· Metal-on-plastic
The basic composition of this implant is a metal femoral head with a liner made up of standard plastic polyethylene. This type of implanted is not recommended for younger, more active patients since standard polyethylene liners are more susceptible to wear and tear. These types of implants are impractical for younger and more active patients as they will more than likely 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. The metal-on-crosslinked polyethylene implant has replaced the less durable metal-on-plastic making it an ideal choice for young, active patients.
· Metal-on-metal
This class of implant is currently the focus of the DePuy hip replacement recall; however, different brands other than DePuy do not have the same reputation. Significant failure rates have not been reported coming from these types of hip implants among other manufacturers. Metal-on-metal implants are known to produce 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
This type of system has an advantage over the other types in that it is more resistant to erosion of its components. Subsequently, these types outperform both metal and plastic with regards to regular wear and tear. Although this type is less likely to cause an allergic response, it is more susceptible to breaks and fractures.
The hip replacement recall places doubt in the safety of hip implants such as DePuy’s . Patients undergoing hip replacement surgery should still research the different types of hip implants that are accessible to them. They should also consult with their surgeons about the hip implant type that is best for them with regards to level of physical activity, age, health, current health of their bones, and other factors. Victims of the hip recall should consult an experienced attorney about receiving proper compensation. For more information about ongoing litigation, visit the DePuy hip implant recall website.
