fracture, Break in a bone, caused by stress. It causes pain, tenderness, and inability to use the part with the fracture. The site appears deformed, swollen, and discoloured, and the bone moves in abnormal ways. It must be protected from weight bearing and movement between the broken ends while it heals, producing puttylike new tissue that hardens to join the broken pieces together. Complications include failure to heal, healing in the wrong position, and loss of function despite good healing. Fractures in joints present a particularly serious problem, often requiring surgery. See also osteoporosis.
