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 .
The Rolando fracture is a type of broken finger involving the base of the thumb. [1] It is an intra-articular fracture. [2] It was first described in 1910 by Silvio Rolando. [3] It is typically T- or Y-shaped. [4]
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.
X-ray of a displaced intra-articular distal radius fracture in an external fixator: The articular surface is widely displaced and irregular. Diagnosis may be evident clinically when the distal radius is deformed, but should be confirmed by X-ray .
At one extreme, a stable undisplaced extra-articular fracture has an excellent prognosis. On the other hand, an unstable, displaced intra-articular fracture is difficult to treat and has a poor prognosis without operative intervention. [citation needed] Eponyms such as Colles', Smith's, and Barton's fractures are discouraged. [by whom?]
Chauffeur's fracture, also known as Hutchinson fracture, is a type of intraarticular oblique fracture of the radial styloid process in the forearm. [1] The injury is typically caused by compression of the scaphoid bone of the hand against the styloid process of the distal radius. It can be caused by falling onto an outstretched hand.
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 .
Gartland & Werley classification is a system of categorizing Colles' fractures. In the Gartland & Werley classification system there are three types of fractures. The classification system is based on metaphysical comminution, intra-articular extension and displacement, and was first published in 1951. [1] [2]
