Hip replacement surgery is a common procedure performed on patients suffering from hip pain and mobility issues. Studies suggest that hip replacement has a high effectiveness and success rate, with more than 90% of patients experiencing pain relief even after five years.
While the surgery itself is typically successful, the choice of hip implant material is critical for the long-term success of the implant. The wrong material can cause complications, affect the longevity of the implant, and ultimately impact the patient’s quality of life.
In this article, we’ll explore the different types of hip implant materials along with their unique pros and cons. Plus, we will also tackle the various factors to consider when choosing a material.
What are the types of hip implant materials?
The material of the hip implant plays a significant role in the success of the surgery. The wrong material can lead to complications and implant failure, ultimately impacting the patient’s quality of life.
Moreover, hip implants should be made of strong and durable material that can withstand the heavy stress placed upon the hip on a daily basis. They should also possess certain qualities, such as biocompatible or non-toxic, low friction, and wear-resistant,
There are three main types of hip implant materials: metal, ceramic, and polyethylene. Each material has its own set of advantages and disadvantages.
Metal implants are known for their durability and resistance to wear and tear. They are typically made from alloys like cobalt-chromium or titanium. However, metal implants can release metal ions into the bloodstream, causing an inflammatory reaction and potentially leading to a condition called metallosis.
Metallosis can cause inflammation, pain, and other health problems. Additionally, patients who are allergic to metals may not be suitable candidates for metal implants.
Ceramic hip implants are a popular option for hip replacement surgery due to their strength, durability, and biocompatibility. These implants are made from a special type of ceramic called alumina or zirconia, which is known for its high strength and low wear rate. Here are some of the main advantages of a ceramic hip implant:
- Resists wear and tear – ceramic hip implants have a lower risk of breaking down over time and are less likely to require revision surgery compared to other implant materials.
- Biocompatible – this means that ceramic implants are less likely to cause an inflammatory response in the body. This is particularly important for patients with allergies or sensitivities to other implant materials, such as metal.
- Low friction – ceramic implants have a smooth surface, which means they can greatly reduce the friction created between the implant and surrounding tissue during movement. This, then, leads to less pain and a quicker recovery time for patients.
However, there are some potential downsides to ceramic hip implants. They can be brittle than other materials, making them more susceptible to fractures.
When this happens, patients may then need to undergo revision surgery to repair the fracture and remove loose bodies in the joint.
Polyethylene is a type of plastic commonly used in hip implant materials. Polyethylene hip implants are known for their durability, biocompatibility, and low cost.
They consist of a metal stem that is inserted into the femur, a metal or ceramic ball that replaces the head of the femur, and a polyethylene cup that replaces the damaged hip socket.
Some of the main benefits of a polyethylene hip implant material include the following:
- Durability – polyethylene can withstand wear and tear over time, which means they have a lower risk of breaking down and requiring revision surgery.
- Biocompatibility – polyethylene implants are also non-toxic, which means they are less likely to cause an inflammatory response in the body.
- Low cost – polyethylene is more cost-efficient than other materials. This can make them a more accessible option for patients who may not have the means to afford more expensive implant materials.
However, there are some potential downsides to polyethylene hip implants. Over time, the wear and tear on the implant can cause the release of tiny particles of polyethylene, which can cause inflammation and damage to surrounding tissue.
Unfortunately, it can further lead to osteolysis, wherein the bone tissues soften, lose their minerals, and then gradually degenerates. When this happens, your implant can become loose, requiring you to undergo revision surgery.
To combat this issue, manufacturers have developed newer forms of polyethylene, such as highly cross-linked polyethylene, which can reduce the amount of wear and tear on the implant and lower the risk of osteolysis.
What are the considerations when choosing hip implant material?
Several factors come into play when selecting the right hip implant material. A patient’s age and lifestyle, the type and severity of the hip condition, and the patient’s overall health and medical history are all important considerations.
The surgeon’s expertise and experience with specific materials can also play a role in the decision-making process. Additionally, when choosing a material, regulatory guidelines and approval processes for hip implant materials should be considered.
