Specialty. Orthopedics. 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.
Following a tibial plateau fracture, the patient is at risk for arthritis. This is referred to as post-traumatic arthritis. The more displaced the joint intra-articular surface is, the more likely post-traumatic arthritis is to occur. This occurs due to injury to the joint surface cartilage. When cartilage is damaged, arthritis can occur. [15]
The Sanders classification system is the most commonly used system for categorizing intra-articular fractures. There are 4 types: [citation needed] Type I fractures are non-displaced fractures (displacement < 2 mm). Type II fractures consist of a single intra-articular fracture that divides the calcaneus into 2 pieces.
Colles fractures occur in all age groups, although certain patterns follow an age distribution. [citation needed] In the elderly, because of the weaker cortex, the fracture is more often extra-articular. Younger individuals tend to require a higher energy force to cause the fracture and tend to have more complex intra-articular fractures.
Bennett's fracture. The Bennett fracture is an oblique intraarticular metacarpal fracture dislocation, caused by an axial force directed against the partially flexed metacarpal. This type of compression along the metacarpal bone is often sustained when a person punches a hard object, such as the skull or tibia of an opponent, or a wall.
Chauffeur's fracture; Other names: Hutchinson fracture, backfire fracture: Fracture of the radial styloid process with the fracture line extending into the intraarticular surface: X-ray of a displaced intra-articular distal radius fracture in an external fixator. The articular surface is widely displaced and irregular. This is a Chauffeur's ...
Specialty. Orthopedic. A Barton's fracture is a type of wrist injury where there is a broken bone associated with a dislocated bone in the wrist, typically occurring after falling on top of a bent wrist. [1] It is an intra-articular fracture of the distal radius with dislocation of the radiocarpal joint. [2]
Orthopedics. Diagnostic method. X-ray, MRI. A bone fracture (abbreviated FRX or Fx, Fx, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
