Document Summary
A disruption or break in the continuity of the structure of bone; commonly caused by traumatic injuries and can be secondary to a disease process (pathological) Classification: open/closed communication/non- communication with external environment, complete/incomplete bone is still in one piece or break is completely through. Immediate localized pain: decreased function, guards and protects against movement. Unnecessary movement increases soft tissue damage and may convert a closed fracture to an open fracture or create further injury. Fracture hematoma -- bleeding, usually occurs in initial 72 hours after injury. Granulation tissue -- active phagocytosis absorbs the products of local necrosis, hematoma converts to granulation tissue and produces basis for new bone substance 3 to 14 hours after injury. Callus formation -- minerals deposited and woven about fracture parts, primarily composted of cartilage, osteoblasts, calcium, and phosphorus. Ossification -- callus ossification from 3 weeks to 6 months after fracture. Consolidation -- distance between bone fragments diminish and eventually close.
