An extra-articular fracture features a break above the wrist joint; the fracture does not extend into the joint itself. Intra-articular fractures are wrist fractures that affect the wrist joint. The distal radius is fractured, including the joint.
What is an articular fracture?
An articular or periarticular fracture happens when a bone breaks inside or around a joint. These injuries often damage cartilage at the ends of bones (articular cartilage) and other joint tissues, requiring special care.
What is meant by intra-articular fracture?
An intra-articular fracture refers to a fracture that extends from the bone into the nearby joint. In the case of radial fractures, this means that the fracture has extended from the end of the radius (the larger of the two bones in the forearm) into the wrist joint.
Is a Colles fracture intra-articular or extra-articular?
Colles fractures are very common extra-articular fractures of the distal radius that occur as the result of a fall onto an outstretched hand. They consist of a fracture of the distal radial metaphyseal region with dorsal angulation and impaction, but without the involvement of the articular surface.
What is an extra-articular?
Extra-articular means outside of or other than a joint. RA affects your joints, as well as other systems in your body. Therefore, you can also call these manifestations or effects systemic. RA inflammation affects your joints through swelling, pain, and potentially joint damage.
What is an extra-articular ligament?
Other extra-articular (outside the knee joint) structures, especially on the lateral (outer side of the knee joint) side of the knee, also provide rotational control to the knee. This ligament runs along the lateral outer aspect of the knee, between the femur and the tibia.
What does articular mean anatomy?
Definition of articular : of or relating to a joint articular cartilage.
What is Colle fracture?
The Colles fracture is defined as a distal radius fracture with dorsal comminution, dorsal angulation, dorsal displacement, radial shortening, and an associated fracture of the ulnar styloid. [1] The term Colles fracture is often used eponymously for distal fractures with dorsal angulation.
What is a Pott fracture?
A Pott’s fracture is a fracture affecting one or both of the malleoli. During activities such as landing from a jump (volleyball, basketball) or when rolling an ankle, a certain amount of stress is placed on the tibia and fibula and the ankle joint.
What is extra-articular Tenodesis?
Background: A modified Lemaire lateral extra-articular tenodesis (LET) is a procedure that is designed to address anterolateral complex (ALC) deficiency. The procedure is performed as an augmentation to anterior cruciate ligament reconstruction (ACLR) to reduce anterolateral rotatory laxity.
What is an intra articular fracture?
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. Compared to extraarticular fractures, intraarticular have a higher risk for developing long-term complications, such as posttraumatic osteoarthritis.
What is the difference between a fracture and dislocation?
As nouns the difference between fracture and dislocation is that fracture is the act of breaking, or something that has broken, especially that in bone or cartilage while dislocation is the act of displacing, or the state of being displaced. is to break, or cause something to break.
What fracture is called a closed fracture?
If the bone is in many pieces, it is called a comminuted fracture. In a non-displaced fracture, the bone cracks either part or all of the way through, but does move and maintains its proper alignment. A closed fracture is when the bone breaks but there is no puncture or open wound in the skin.
What is intra – articular step off?
Intra-articular “step-offs” are a complication of intra-articular fractures. A “step-off” is a type of malunion in which the bone heals, but it heals so that the joint surfaces are not aligned in a smooth continuous surface. Like all organ systems, bones require a blood supply.
