Nowadays various kinds of metal implants are used in orthopedic implants that are used to treat fracture repair and joint replacement surgery. But some people are concerned about the allergic reaction that might occur due to presence of these materials. Due to this it can cause irritation or pain after surgery.

Most people compalin of hypersensitivity or allergy that might occur after the material comes in contact with various metal. This is because they have sensitive skin and metal inside the implant might not suit their body. Any screws manufacturer uses the base material which is found in highest quantity while the alloys are found in small quantities.

Orthopedic implants are generally made up of metals and a type of plastic called polyethylene. These two are common materials which are combined in most joint implants. When these are properly designed the two materials can rub smoothly and minimize wear.

Some materials are known for their excellent characteristics and they are made from a mixture of two or more metals. Such mixture of materials are known as alloy. A new material can be created that has a good balance of all materials to get the desired chracteristrics. Some of the most common alloys are cobalt-chromium,stainless steel and titanium. Here are some of the common metals for an orthopedic implant:

Titanium: It is one of the most common materials used in implants where strength is not an important factor. For example it is used in fibre metal which is a layer of metal fibers that are used to club the surface of the implant so that the bone can grow. The cement should flow into the implant to withstand the implant well.

Cobalt-chromium alloys: These are known for their strong,hard and biocompatible chracteristics. They are used for various kinds of joint implant replacement as well as fracture repair implants and need along service. It primarily comprises of cobalt and chromium and number of other materials like molybdenum that helps to increase their strength.

Tantalum: It is a pure metal which has excellent physical and biological characteristics. It is non-corrosive,biocompatible and flexible in nature.

Titanium alloys: They are mostly known to be biocompatible. They are most flexible of all alloys. Titanium is used as the base material and is much lighter in weight than other alloys. It also comprises of some varying degree of materials like vanadium and aluminium. It is one of the most common metals used in surgical implants.

Polyethylene: It is kind of plastic which is used on the surface of the one implant to join the another. Usually it is kind of joint replacement and you can recognize this material which is used to make milk cartons. It is not made of recycled milk cartons but of polyethylene which are used in orthopedic implants of much higher quality. Infact a special type of medical-grade polyethylene is used for orthpedic implants.

These are some of the common materials that are used in orthopedic implants.
