Tennis player elbow
Lateral epicondylitis, the disease is also known as the elbow tennis player, is not necessarily found in tennis people. Indeed, a power impact on top in tennis can lead to overvoltage of the muscles and the luxury area tendons, which is the main cause of epicondylitis. However, other activities (for example, painting work or wood sawmills), which are accompanied by repeating movements in the elbow, can contribute to the development of epicondylitis.
The source of pain in epicondylitis is localized in a small elevation located near the elbow joint. It is called lateral supermarket. The muscles of the forearm participating in the extension of the brush are attached to the lateral supermarket with the help of tendons. Tendons consist of collagen fibers - thin elastic strands located in parallel to each other. One end tendon is attached to the muscle, and the other is woven into the periosteum - the shell that covers the bone. When cutting the muscle, this effort is transmitted to the tendon, and through it to the bone.
Overvoltage of muscles and tendons in the elbow area is the main cause of the development of epicondylitis.
Repeating power movements in the elbow joint can contribute to the abitratus of the elbow tendons. It does not have to be the extensible loads in professional tennis. Clogging of nails, wearing buckets with water in the country, trigging bushes - all this can lead to the development of the elbow of the tennis player.
In case of damage to the tissues, inflammation is developing, which is a protective reaction of the body. Leukocytes migrate into the focus of inflammation, cleaning it from damaged tissues and contributes to healing. In medical terminology of disease, accompanied by inflammation, have an end. For example, inflammation of tendons is called tendonitis. Accordingly, the inflammation of the tissues near the lateral screwdriver is called lateral epicondylitis.
It should be noted that the elbow of the tennis player is not always accompanied by inflammation of tissues. In the absence of inflammatory changes in the tendons, the disease is called a tendinosis. In case of tendinosis, tensile and micrographs lead to degenerative changes in the tendon. In such a tendon, the location of collagen fibers is disturbed. The cells of the tendon begin to be replaced by fibroblasts - cells that produce a slightly different type of collagen, not so durable and without ordered location of the fibers. Gradually, the flow of the tendon is reborn: it becomes thicker due to the growth of the defective connective tissue. Naturally, such a tendon may be damaged even with minor injuries.
The exact mechanism of development of epicondylitis is still not known. According to one common hypothesis, in tendons attached to the lateral supermarket, micrographs appear due to the overload. The continuation of the integrity of the tendon is hampered by the ongoing loads, which can also lead to the formation of new damage. The growth of the connective tissue in the place of damage leads to a weakening of the tendon and the occurrence of pain.
