title: Joint arthroplasties and prostheses.
abstract: Joint arthroplasty is the most frequently performed orthopedic procedure after fracture fixation. The major indications for any joint replacement are degenerative joint disease, inflammatory arthropathy, avascular necrosis, and complicated fractures. The major contraindications for any joint arthroplasty are systemic and joint infection and a neuropathic joint. The interpretation of radiographs in cases of joint arthroplasty is a significant part of many radiology practices, and correct recognition of the prosthetic devices and their complications by the radiologist is important. The article reviews the most common types of joint arthroplasties and prostheses of the upper and lower extremities and discusses the most frequent complications associated with their placement.
