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 ...
A flexion teardrop fracture is a fracture of the anteroinferior aspect of a cervical vertebral body due to flexion of the spine along with vertical axial compression. [1] The fracture continues sagittally through the vertebral body, and is associated with deformity of the body and subluxation or dislocation of the facet joints at the injured level. [2]
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 ]
The fracture is often unstable. [1] Treatment may be conservative with the use of a brace or via surgery. [1] The fracture is currently rare. [7] It was first described by G. Q. Chance, a radiologist from Manchester, UK, in 1948. [3] [13] The fracture was more common in the 1950s and 1960s before shoulder harnesses became common. [3] [5]

Fragility fracture is a type of pathologic fracture that occurs as a result of an injury that would be insufficient to cause fracture in a normal bone. [2] There are three fracture sites said to be typical of fragility fractures: vertebral fractures, fractures of the neck of the femur, and Colles fracture of the wrist. This definition arises ...
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.
Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [ 1 ] especially in the femur and tibial bones, but can also occur genetically at birth.
