Document Summary
Feb 1: ch 13 : recognizing different sports injuries: no matter how much time is spent on injury prevention, sooner or later an injury occurs, either acute or chronic in nature, acute injuries: result of trauma (ex. Achillies tendon rupture: chronic: caused by repetitive, overuse activities (found in endurance sports. Treatment doesn"t work so we have to do educated guessing. Fractures: result of extreme stress and strain on bone. Anatomical characteristics: bone is made of dense connective tissue matrix. This reduces friction between articulating bone: periosteum dense, white fibrous covering which penetrates bone via sharpey fibres, contains blood vessels and osteoblasts. Greenstick fracture: when we have an incomplete fracture that occurs on the convex surface, concave surface stays intact, we see this in youth. Transverse fracture: occurs in a straight line, moi will be an object impact. Linear fracture: due to falling from a height.
