Prior to the 19th century most patella fractures were treated non-surgically with extension splinting, frequently resulting in poorly joined fragments of bone and long-term pain and disability. [6] Incomplete understanding of the importance of the patella led to the trend of removing the whole patella, also resulting in pain, disability and ...
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 .
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing.

An old fracture with nonunion of the fracture fragments. Some fractures may lead to serious complications including a condition known as compartment syndrome. If not treated, eventually, compartment syndrome may require amputation of the affected limb. Other complications may include non-union, where the fractured bone fails to heal, or ...
[1] [2] The patella is also often felt and seen out of place. [1] Complications may include a patella fracture or arthritis. [3] A patellar dislocation typically occurs when the knee is straight and the lower leg is bent outwards when twisting. [1] [2] Occasionally, it occurs when the knee is bent and the patella is struck directly. [1]
Triboluminescence is a phenomenon in which light is generated when a material is mechanically pulled apart, ripped, scratched, crushed, or rubbed (see tribology). The phenomenon is not fully understood but appears in most cases to be caused by the separation and reunification of static electric charges , see also triboelectric effect .
It is important to note to distinguish this radiographic finding from that of a medial femoral condyle avulsion fracture, which is an injury in which a pulling force of a tendon or ligament fractures away a piece of the bone from its attachment site. [2] Pellegrini-Stieda Syndrome, shown as marked on the imaging.
An avulsion fracture is a bone fracture which occurs when a fragment of bone tears away from the main mass of bone as a result of physical trauma. This can occur at the ligament by the application of forces external to the body (such as a fall or pull) or at the tendon by a muscular contraction that is stronger than the forces holding the bone ...
