An intraarticular fracture is a bone fracture in which the break crosses into the surface of a joint. This always results in damage to the cartilage. [1] Compared to extraarticular fractures, intraarticular have a higher risk for developing long-term complications, such as posttraumatic osteoarthritis. [2]
An intraarticular fracture is a fracture that crosses a joint surface. Such fractures also involve some cartilage damage. Fractures to joints are more complicated to treat and heal than simple fractures, as multiple bones are involved.
While intra-articular fractures appear very similar to those that do not involve a joint space (extra-articular fractures), intra-articular fractures are significantly more serious because they are associated with a much greater incidence of long-term complications.
Posttraumatic osteoarthritis (PTOA) represents end-stage organ level failure of an injured joint, typically occurring after an intraarticular fracture (IAF). The initial impact to the cartilage, combined with the ensuing pathomechanical and pathobiological response of the cartilage, lead to PTOA.
An intra-articular fracture is a complex injury, of which the fracture forms just one part. From the perspective of immediate or early complications, failure of the soft tissue component possess the greatest risk of poor outcome.
Intra-articular fracture — An intra-articular fracture is one that extends into the wrist joint. ("Articular" means "joint.") Extra-articular fracture — A fracture that does not extend into the joint is called an extra-articular fracture. Open fracture — When a fractured bone breaks the skin, it is called an open fracture. These types of ...
Identifying the articular injury is the first step. Stable anatomic reconstruction for displaced fractures. Prevent displacement for stable non-displaced fractures treated nonoperatively. Joint range of motion to promote synovial fluid nutrition to chondrocytes.
While bones are made of hard, dense materials, any bone can break with enough force. Articular (or intraarticular) and periarticular fractures happen when bones break near or inside a joint. These fractures usually damage cartilage but also may affect other joint tissues.
Intra-articular calcaneal fractures are challenging injuries to manage for both patients and surgeons given their association with both early and late complications. This article aims to review the management, classification systems, surgical approaches, and care regarding intra-articular calcaneal fractures.
3 Mechanism of injury. There are two common mechanisms of injury for articular fractures: Indirect application of force, producing a bending moment through the joint and drives a part of the joint into its opposing articular surface.
