Soft tissues Types of injuries and the causes The Inflammatory process Sprain vs Strain Different jumps MOT Ans to problem Ligament Tendon Muscle Cells, collagen fibers and proteoglycals Consists of type I collagen Made up of myofibrils; composed of protein filaments (actin and myosin) Parallel, oblique or Fibre arrangement even spiral Parallel errors of tropocollagen Unipennate, multipennete or fusiform patterns Function •Connects muscles to bone • Producing motion and contributing to joint stabilization. Permit movement and maintain posture. Microscopic structure •Connects bone to bone • Passively stabilizes the joints • Proprioceptive function •Soft tissue injuries cartilage muscle ligament tendon •Skeletal injuries (fractures) Tendons Acute/ overuse injuries Tendinosis/Tendinitis Tenosynovitis (inflammation/irritation) Avulsion Ligaments acute trauma Total/ partial rupture Muscles Distension Direct trauma resulting in contusion of the muscle Inflammation is a local response that occurs in vascularized tissue in response to loading of sufficient magnitude that it results in cell damage. Begins with bleeding and plasma exudation Initiates clotting Forms a meshwork of fibrin, fibronectin and collagen Last a few days Accumulation of large numbers of endothelial cells, myofibroblasts and fibroblasts at the site of injury. Ingrowth of capillaries begin Lasts for a few weeks Establishes the final tissue structure through continuous remodelling of the scar tissue. No. of macrophages is significantly reduced and mature blood supply is established Lasts several months Sprain Strain A sprain is an injury to a ligament. A ligament is a thick, tough, fibrous tissue that connects bones together A strain is an injury to a muscle or tendon. Muscles move your skeleton in an amazing variety of ways. http://orthopedics.about.com/cs/sprainsstrains/a/sprain.htm Three types of movements associated with muscles movements. They are static, concentric and eccentric. ACTION! DEFINITON! Static Non-moving position of a muscle. The length of the muscle does not change. Concentric Shortening of the muscle. Eccentric Lengthening of the muscle. JUMPS! HOW? Standing Jump Starts from a stationary semisquatted position, does not preliminary employ a downward phase and thus does not involve prestretching of muscles. Countermovement Jump Starts from an upright standing position, makes a preliminary downward movement, and then extending it to jump vertically up off the ground. Drop Jump Drop down from a specified height and then jumps upwards. Myositis: a type in which connective tissue forms within the muscle. Ossificans: the deposit of bone in muscle tissue, causing pain and swelling. http://medical-dictionary.thefreedictionary.com/Myositis+ossificans+traumatica Andreas uses countermovement jump and suffered a sprain on the tendon. He suffered tendinitis.
