Many running athletic shoe stores can watch you run or walk and help you to pick out a shoe or make an orthodox insert that will keep you from pronating or inverting. One way to avoid an overuse injury would be to modify your workout with cross training. For example, cross training for running would be a stair climber and cross-country skiing, because these machines target similar muscle groups. Cross training can also be varying the type of intensity and changing the sequence of machines. A fracture can be a complete break, a chip, or a crack in a bone.
Fractures are either open or closed.
In a closed fracture, the skin is not broken. Indirect force-Trauma is inflicted at a distance from the resulting fracture. An example of this is falling on the outstretched hand and sustaining a fracture of the clavicle. Avulsion force-A portion of the bone is pulled off by the attached muscle, tendon or ligament. If a fracture is present, the main features are unnatural mobility of the body part, deformity, local tenderness over the bone and crackling sounds during movement.
