Metallic Alloys eMedicine Orthopedics
Metal has been used extensively in the manufacturing of orthopedic implants in a multitude of different forms. Multiple different materials throughout history have been tested as replacements for bone. Materials as diverse as ivory, wood, rubber, acrylic, and Bakelite have been used in the manufacture of prosthetic implants.
The extensive use in modern times of metallic alloys is related to the availability and success at the beginning of the 20th century of several different alloys made of the noble metals. Implants made from iron, cobalt, chromium, titanium, and tantalum are commonly used. Clinical studies have demonstrated that alloys made from these metals can be used safely and effectively in the manufacturing of orthopedic implants that are left in vivo for extended periods. The mechanical, biologic, and physical properties of these materials play significant roles in the longevity of these implants.
