Document Summary
~6 weeks for bones of arms and legs (long bones) 3 weeks for bones of hands and feet (small bones) Fracture healing requires osteoblast activity to lay down bone and form callus (new bone) Following cast removal, normal stresses and strain will aid in healing and remodeling process. Osteoclasts assist in re-shaping of bone in response to normal stress. So tends to remove cast before tissue fully recover. Most common fracture that results from physical activity. Altered stress distribution due to muscle fatigue. Initially pain during activity and then progresses to pain following activity. If suspected: stop activity for 14 days. Small fracture that can heal on its own. At least 1 bone in a joint is forced completely out of normal and proper alignment (require surgery) High level of incidence in fingers, elbow and shoulder. Partial dislocation causing incomplete separation of 2 bones. Often occur in shoulder and females (patella)
