Orthopaedic implants are used by the surgeons to replace a nonfunctioning, damaged or a deformed bone or a joint. A diverse range of orthopaedic implants are made for different parts of the body. For example, implants for the leg might be different from the implants for the spinal cord. But, at times, some implants, which act as connectors could be similar as well, like the screws, nails etc. The orthopaedic implant manufacturers across the world are making topnotch quality implants using different type of materials. Some implants are made using metal, while some are made with plastic. In this article, we will explore a wide range of orthopaedic implants used for different purposes.
Getting to know orthopaedic implants and the materials used for making them
Orthopedic implants manufacturers plays a pivotal role in deciding the quality of the implant. They also play a significant part in fixation process. The decision that you make to choice the right type of implant material, impacts a lot of things. The type of material impacts thebiocompatibility, rigidity, receptivity of the tissue, corrosion and many more things. Additionally, the surface morphology of the material influences the stability within the skeleton. Also, it effects the cement mantle which surrounds.
Qualities of good material used to make orthopaedic implants
- The material should be strong and have superb strength
- The material needs to high fatigue resistance
- Material used to make the orthopaedic implant should be chemically inert
- The implants have to completely biocompatible
- Material should have less elastic modulus
- Material for making the implant should be economical
- It has to be completely corrosion-proof
- The material should have superb wear resistance
- Also, the material used to make the implants has to be certified
A wide range of orthopedic implants
- Metallic implants
Several orthopaedic implants are made using metal and alloys like titanium. It is one of the most commonly used metal to make implants. Metals are recognized globally for superb strength and toughness. Also, they are quite dependable, therefore, once replaced, you won’t have to worry about replacing the replacement that soon. The replacement can stay in for a long time, probably for 10 years. Alloys are mostly used in prosthetics. So, if you want to go for prosthetic hips and knee replacements, then you would have the choice to select metal implants. Metal is used extensively to make the bone plates, nails and screws as well.
Polymers are relatively new. The experts have started using them to make orthopaedic implants as well. Polymers are a preferred choice of the makers for a variety of reasons. They are used extensively to mimic a damaged, degenerated or deformedcartilage or ligaments. Also, if the cartilage has gone through significant trauma, it can be replaced with a polymer implant.For hip and joint replacements, a polymer based implant could be used to adapt to the tissues.
Listed above are a few of the materials used to make orthopaedic implants, apart from these, a few of the other materials like ceramic and plastic are also used to make implants. However, a world-class orthopaedic implant exporter or manufacturer would only choose the best material for making the implants. As, a lot depends on the kind of material which is being used. First of all, the choice of material has to be right. If polymer is required, metal would not be used and vice versa. Apart from that, the companies have to make sure that they test the materials and use only certified material to make the implants.
