A bone fracture (abbreviated FRX or Fx, F x, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. [1]
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...
Fracture with a dorsal tilt. Dorsal is left, and volar is right in the image. There are a number of ways to classify distal radius fractures.Classifications systems are devised to describe patterns of injury which will behave in predictable ways, to distinguish between conditions which have different outcomes or which need different treatments.
For children and adolescents, there are three main categories of fracture: buckle (torus) fractures, greenstick fractures, and complete (or off-ended) fractures. [4] Buckle fractures are an incomplete break in the bone that involves the cortex (outside) of the bone. Buckle fractures are stable and are the most common type. [4]
Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress.The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid.
A compression fracture is a collapse of a vertebra. It may be due to trauma or due to a weakening of the vertebra (compare with burst fracture ). This weakening is seen in patients with osteoporosis or osteogenesis imperfecta , lytic lesions from metastatic or primary tumors , [ 1 ] or infection. [ 2 ]
Nearly 41% of knee dislocations have an associated fracture, with the majority of these fractures in one of the legs. [47] Nerve injury occurs in about 15.3% of knee dislocations, while major artery injury occurs in 7.8% of knee dislocations. [47] More than half (53.5%) of knee dislocations have an associated torn meniscus. [47]
In a complete rupture, the ability to extend that knee is decreased. [1] A pop may be felt when it occurs. [2] Injury to the patellar tendon generally requires a significant force such as falling directly on the knee or jumping from a height. [1] Risk factors include patellar tendinitis, kidney failure, diabetes, and steroid or fluoroquinolone use.
