Fracture

(frak'-tur). The breaking of a bone, either by external force, or by the action of the muscles of the body. Applied also to the breaking of a cartilage. F., Barton's, an oblique fracture of the lower end of the radius, beginning on the articulating surface. F.-bed, a doubly inclined plane used in the treatment of fractures of the hip. F.-box, a long box with no ends or cover, used in the immobilization of fractured bones. F., Capillary, consisting of only a fine crack or fi ure. F., Comminuted, with shattering of the bone. F., Colles', one of the lower end of the radius with displacement backward. F.,Complete, entirely through the bone. Comminuted Fracture of Clavicle. F. (Moullin.) Complicated, with injury of adjacent parts. F., Compound, with a communicating wound of the skin. F., Depre ed, with depre ion of the fractured part below the normal level, as in fracture of the skull. F., Double, one bone is fractured in two places. F., Dupuytren's, fracture of the fibula, with retraction and displacement outward, and with laceration of the ligaments of the foot. F., Epiphyseal, with separation of the epiphysis of a bone. F., Greenstick, one Greenstick Fracture of the Radius. (Moullin.) side of the bone is broken, the other bent. F., Impacted, with forcible compre ion of the fragments into each other. F., Moore's, fracture of the lower end of the radius, with laceration of the internal lateral ligament and detachment of the triangular inter articular cartilage, which allows of the dislocation of the head of the ulna and the imprisonment of the styloid proce under the annular ligaments. F., Pott's, same as F., Dupuytren's, but without laceration of the inferior tibio-fibular ligaments. F., Shepherd's, a fracture of the astragalus, the outer projecting edge being detached. F., Simple, without rupture of the over skin or lower mucous turelying of the end membrane. of the radius, F., a quarterfracof an inch to an inch from the articular surface. F., Spontaneous, with but a slight force to cause it, as when there is disease of the bone. Frsenulum. See Frenulum .
