A prosthesis refers to an implant which is inserted into the body. In terms of orthopaedics this can relate to any metalwork such as screws, plates, pins and also joint replacement components. A fracture can range from a hairline crack through to complete displacement of the bone or fractures in multiple pieces. Periprosthetic fractures refers to a break in the bone surrounding an implant. These fractures may be close enough to the implant that they result in the implant becoming loose.
Periprosthetic joint replacement fractures
These types of fractures can occur around any type of joint replacement: shoulder, elbow, wrist, hip, knee or ankle as well the other less common joint replacement locations. The most common location is in the thighbone (femur) near either a total hip or a total knee replacement
Periprosthetic plate, screw or pin fractures
These types of fractures occur around plates, screws or pins which were generally put in previously to treat earlier fractures. They tend to occur at the ends of the plates or pins but can also result in the metalwork being broken also.
