Other Kinds of Hip Implants Such as those Manufactured by DePuy
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 hip recall , patients are questioning the safety of medical procedures, particularly hip implant surgeries. It is imperative that all patients undergoing hip replacement surgery should research the types of hip implants to help them decide which will best suit their needs. Here are the four most common types:
? Metal-on-plastic
With this type of system, the femoral head is composed of metal while the liner is made up of standard plastic polyethylene. This type is not well suited for patients who are younger and more active since standard polyethylene liners are highly susceptible to erosion. Ultimately, younger and more active patients who are given these types of implants will need revision 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. Other manufacturers have not been reported to have the same failure rates. Before the recall, this class of hip implant had the reputation of producing stability and longevity. It should be noted that patients with any sensitivity or allergy to metal should take caution and avoid this type of hip implant. An inflammatory reaction and/or nerve damage may result from particles released into the bloodstream due to friction of the metal implant components.
? 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. 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 safety of hip implants such as DePuy’s is questionable due to the implant recall. 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. Victims of the hip recall should consult an experienced attorney about receiving proper compensation. Information regarding the hip replacement recall is available on the DePuy implant recall website.
