The Types of Hip Replacements Other than the DePuy ASRs

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 hip replacement 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

The basic composition of this implant is a metal femoral head with a liner 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. 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

Despite being the target of the DePuy hip replacement, not all metal-on-metal replacements come from DePuy pharmaceuticals. Significant failure rates have not been reported coming from these types of hip implants among other manufacturers. 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. 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

These types of systems have the advantage of being more resistant to erosion. With regards to wear and tear, metal-on-ceramic outperforms both metal and plastic types of hip implants. This class is more susceptible to breaks and fractures, but is less likely to cause an inflammatory response.

The hip replacement recall places doubt in the safety and reliability of all types of hip implants such as those from DePuy . Regardless, patients receiving hip replacements should still explore the different types of implants that are available. These patients should talk with their surgeon to find out which type of implant is best suited to their level of physical activity, age, health, current health of their bones, and other factors. Those affected by the hip replacement recall should consult a licensed attorney regarding their options. For more information about ongoing litigation, visit the DePuy hip implant recall website.
