Imaging Review of Different Subchondral Insufficiency Fractures

Abstract Subchondral fractures are a common cause of joint pain that may ultimately lead to articular collapse and the need for arthroplasty. This type of fracture has been reported at multiple joints throughout the body. While clinical and radiographic resolution can be achieved, progressive bone collapse can occur and lead to a variety of complications. Understanding the pertinent imaging findings can aid in the early evaluation of subchondral fractures and in the prevention of their associated complications.
