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.
Endochondral ossification[ 1 ][ 2 ] is one of the two essential pathways by which bone tissue is produced during fetal development of the mammalian skeletal system, the other pathway being intramembranous ossification. Both endochondral and intramembranous processes initiate from a precursor mesenchymal tissue, but their transformations into ...
Cervical vertebra. The pars interarticularis, or pars for short, is the part of a vertebra located between the inferior and superior articular processes of the facet joint. [1][2] In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the ...
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.
Articular surfaces of femur Articular surfaces of tibia. The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or ...
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]
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.
