Materials of prosthesis
materials used in the hip prosthetic implant are various and differ in their durability and coefficient of friction. Orthopedic doctors select the most suitable material of the implant for each patient according to their occupation, activity, age, bone condition, and surgeon’s preference. It is important for patients who are going to have hip arthroplasty to discuss their options of the implant material that fits their needs.
Prosthetic implants nowadays are mainly made from ceramic, plastic, polymers, and metals. Although each material has its pros and cons, they are all effective, bearing, and have long-lasting durability. Metal implants are made of corrosion-resistant titanium alloys, and they are less expensive than other materials, yet they contain cobalt, chromium ad nickel that may cause an undesired reaction for some people. It is believed that ceramic on plastic is the most wear-resistant and commonly used material in hip prosthetic implants. The eroded and unstable thigh bone is better to be affixed with the prosthetic implant using cement while healthy bone gets porous implant through which bone grows and adheres.
