Skeletal Injuries (sprain, strain, dislocation and fracture) and causes of skeletal injuries
Skeletal injuries can be classified as sprain, strain, dislocation and fracture. Adequate treatment given at the time of injury is very important in good anatomical repair and functional recovery. If it is not given, it may lead to further injure, shock and permanent disabilities. Sprain and are joint injuries in which there is no displacement of join surfaces. In a dislocation there is displacement of bones at the joint. A fracture is partial complete break in the continuity of a bone (periosteum).
What are the causes of skeletal injuries?
Most of these injuries are the result of trauma, direct or indirect. A bone can be fractured directly at the point a blow is applied. An indirect force may cause the bone to break away from the spot of application of force e.g. fracture of clavicle after a fall on the outstretched hand. Violent cont-action of group of muscles may pull pieces of bone away from the point where the muscle is attached i.e. fracture of patella by powerful contraction of quadriceps muscles. Wrenching of a joint can cause its ligaments to pull so hard at the bones forming the joint, that one of the bones may fracture, e.g. fracture of lower leg bone at the ankle after stumbling. Pathological fracture: the bone may be the seat of a number of diseases, which weaken it, and make it liable to break even with very injuries.
