What is the difference between intra-articular fracture and extra articular fracture?

What is the difference between intra-articular fracture and extra articular fracture?

Fracture types can be described as “extra – articular” (which means the fracture line does not extend into the joint) or “intra – articular” ( which means the fracture line does extend into the joint; this is the more serious type of fracture).

What is an example of an intracapsular fracture?

An intracapsular fracture is a bone fracture located within the joint capsule. Examples of intracapsular fractures includes: In the hip: Fractures of the femoral head and femoral neck.

What is the difference between intraarticular and Extraarticular?

As adjectives the difference between extraarticular and intraarticular. is that extraarticular is (anatomy) situated outside of a joint while intraarticular is (anatomy) situated within a 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 does intra-articular?

: situated within, occurring within, or administered by entering a joint. Other Words from intra-articular. intra-articularly adverb.

What is intra-articular surface?

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 are intracapsular ligaments?

Intracapsular ligaments are located inside the articular capsule and include the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). Both lie in the middle of the capsule, together forming an X-shape.

What is intracapsular fracture of femur?

Femoral neck fractures are intracapsular fractures. The capsule is the area that contains the fluid that lubricates and nourishes the hip joint. Fractures in this area are categorized based on the location of the fracture along the femoral neck: subcapital is the femoral head and neck junction.

What are intra-articular structures?

Intra-articular fibrocartilages are complete or incomplete plates of fibrocartilage that are attached to the joint capsule (the investing ligament) and that stretch across the joint cavity between a pair of conarticular surfaces. When complete they are called disks; when incomplete they are called menisci.

Is the MCL intraarticular or Extraarticular?

The MCL and the ACL are two commonly injured structures that are typically studied with animal models. Because the MCL is extraarticular and the ACL is intraarticular, these two ligaments respond differently to injury. Smaller animals are typically used to model the MCL given its surgical accessibility.

What causes intra-articular fracture?

: an intraarticular fracture of the ulnar (volar) portion of the distal radius, usually caused by direct impaction of the lunate onto the lunate fossa of the distal radius.
