Periprosthetic in medicine refers to a structure in close relation to an implant. Clinically it can refer to: Bone fracture or 'periprosthetic fracture' [1] around an artificial joint, e.g. after a knee replacement; infection around an artificial joint or 'periprosthetic joint infection' [2] Vegetation or leak around an artificial heart valve
The most common symptom of periprosthetic joint infections is joint pain. [2] Other local symptoms are also present, including erythema (redness of the joint), joint swelling, warmth of the joint, and loosening of the prosthetic joint. [2]
Periprosthetic fractures are becoming more frequent with the aging patient population and can occur intraoperatively or postoperatively. Depending on the location of the fracture and the stability of the prosthesis, these can be treated surgically with open reduction and internal fixation or revision of the prosthesis.

(h) oblique fracture Open ankle fracture with luxation Periprosthetic fracture of left femur. In orthopedic medicine, fractures are classified in various ways. Historically they are named after the physician who first described the fracture conditions, however, there are more systematic classifications as well. [citation needed]
A hip fracture is a break that occurs in the upper part of the femur (thigh bone), at the femoral neck or (rarely) the femoral head. [2] Symptoms may include pain around the hip, particularly with movement, and shortening of the leg. [2] Usually the person cannot walk. [3] A hip fracture is usually a femoral neck fracture.
Heterotopic ossification of varying severity can be caused by surgery or trauma to the hips and legs. About every third patient who has total hip arthroplasty (joint replacement) or a severe fracture of the long bones of the lower leg will develop heterotopic ossification, but is uncommonly symptomatic.
A femoral fracture is a bone fracture that involves the femur. They are typically sustained in high-impact trauma, such as car crashes , due to the large amount of force needed to break the bone. Fractures of the diaphysis , or middle of the femur, are managed differently from those at the head, neck, and trochanter ; those are conventionally ...
Osteolysis is an active resorption of bone matrix by osteoclasts and can be interpreted as the reverse of ossification.Although osteoclasts are active during the natural formation of healthy bone the term "osteolysis" specifically refers to a pathological process.
