An orthopedic implant is a medical device manufactured to replace a missing joint or bone or to support a damaged bone. The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage.

Internal fixation Internal fixation is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone, a concept that dates to the mid-nineteenth century and was made applicable for routine treatment in the m ...

is an operation in orthopedics that involves the surgical implementation of implants for the purpose of repairing a bone. During the surgery of broken bones through internal fixation the bone fragments are first reduced into their normal alignment then they are held together with the help of internal fixators such as plates, screws, nails, pins and wires.
