| kocher fracture | <radiology> Osteochondral fracture of the capitellum (12 Dec 1998) |
|---|---|
| fissured fracture | A fracture running parallel with the long axis of the bone. Synonym: fissured fracture. (05 Mar 2000) |
| foetal fracture | A fracture of one or more bones of a foetus occurring before birth. Synonym: foetal fracture. (05 Mar 2000) |
| folding fracture | A deformity in children consisting of a local bulging caused by the longitudinal compression of the soft bone; it occurs commonly in the radius or ulna or both. Synonym: folding fracture. (05 Mar 2000) |
| fracture | <orthopaedics> A break or rupture in the cortex of bone. The act of breaking a bone. Origin: L. Fractura, from frangere = to break (09 Oct 1997) |
| fracture bed | A narrow, extra-firm bed for treatment of fractures; usually incorporates an overhead frame for traction apparatus. (05 Mar 2000) |
| fracture by contrecoup | Skull fracture at a point distant from the site of impact. (05 Mar 2000) |
| fracture dislocation | Dislocation associated with or accompanied by a fracture. (05 Mar 2000) |
| fracture fixation | The use of metallic devices inserted into or through bone to hold a fracture in a set position and alignment while it heals. (12 Dec 1998) |
| fracture fixation, internal | The use of internal devices (metal plates, nails, rods, etc.) to hold the position of a fracture in proper alignment. (12 Dec 1998) |
| fracture healing | The physiological restoration of bone tissue and function after a fracture. It includes callus formation and normal replacement of bone tissue. (12 Dec 1998) |
| freeze fracture | Method of specimen preparation for the electron microscope in which rapidly frozen tissue is cracked so as to produce a fracture plane through the specimen. The surface of the fracture plane is then shadowed by heavy metal vapour, strengthened by a carbon film and the underlying specimen is digested away, leaving a replica that can be picked up on a grid and examined in the transmission electron microscope. The great advantage of the method is that the fracture plane tends to pass along the centre of lipid bilayers and it is therefore possible to get en face views of membranes that reveal the pattern of Integral membrane proteins. The E face is the outer lamella of the plasma membrane viewed as if from within the cell, the P face the inner lamella viewed from outside the cell. Fracture planes also often pass along lines of weakness such as the interface between cytoplasm and membrane, so that outer and inner membrane surfaces can be viewed. Further information about the structure can be revealed by freeze etching. Extremely rapid freezing followed by deep etching has allowed the structure of the cytoplasm to be studied without the artefacts that might be introduced by fixation. (18 Nov 1997) |
| lefort fracture | <radiology> Types: I transverse fracture through floor of maxillary sinuses (only palate moves), II through maxillary sinuses (pyramidal fracture), III through orbits (craniofacial dysjunction), clinically, may be mixed (12 Dec 1998) |
| linear fracture | A fracture running parallel with the long axis of the bone. Synonym: fissured fracture. (05 Mar 2000) |
| linear skull fracture | A skull fracture resembling a line. (05 Mar 2000) |
