In the early years, “tennis elbow” was named after tennis players who were prone to the disease, and the medical name was lateral humeral epicondylitis, used to describe a series of symptoms that occur mainly in the lateral part of the elbow joint pain. Nowadays, the name “tennis elbow” is not true anymore, but IT people, housewives, carpenters, plasterers, mahjong players and other people who need to work with their hands and wrists repeatedly are prone to this disease. The onset of the disease is mostly slow, and patients feel pain in the upper part of the elbow joint, and the pain can sometimes radiate upward or downward, making them feel sore and uncomfortable and reluctant to move. The pain can be aggravated by wringing the towel, moving, clicking the mouse, turning the hand and pushing the ping-pong ball, and other movements with the nature of elbow and wrist flexion and extension rotation. On examination, there are usually limited pressure points at the lateral epicondyle of the humerus. The lesion is mainly in the tendinous part of the radial wrist extensor muscle at the attachment of the humeral epicondyle, but it can also spread to the radial wrist extensor and the common finger extensor muscle. There is a tiny vascular nerve bundle at this site, which occurs deep from the muscle and tendon, crosses the myofascia or tendon membrane, and finally crosses the deep fascia and enters the subcutaneous tissue. Myofasciitis at the muscle attachment will cause strangulation of this neurovascular bundle and is the main factor causing pain. And cold and fatigue are the main triggering factors. Based on more than ten years of clinical treatment and follow-up experience, we suggest: 1. Early treatment: regular conservative treatment at the early stage of the onset of the disease, and satisfactory results can be obtained within a few days. 2, triangular towel suspension paste chest position fixed 1-2 weeks, keep warm: in the affected limb in the flexion of the elbow, forearm rotation posterior position when the extensor muscle group is in a relaxed state, pain is relieved, soft tissue to get rest. Because removing the triggering factors and allowing the soft tissues to get sufficient rest is the top priority of treatment. Restriction of wrist and elbow activities, especially the clenching of fists and wrist extensions, is the basic principle in the treatment and prevention of recurrence of tennis elbow. Generally soft tissue sterile inflammation can be more completely absorbed in about 2 weeks, so patients who can insist on braking for 2 weeks tend to have a significant treatment effect, and the probability of recurrence will be reduced. 3, oral anti-inflammatory and analgesic drugs or ointment and plaster on the affected area to assist, can improve pain and increase the effectiveness of treatment. 4.Closure treatment. Clearly identify the pain point injection is the key. Generally use the mixture of Chrysanthemum and lidocaine, lidocaine is anesthesia, after the completion of closure, press the original pain point, such as pain symptoms completely disappeared that the injection site is accurate, at this time supplemented by braking effect is better. 5. Surgical release: Most of the above treatments can be cured, and for those who are not effective, surgical treatment can be considered, such as peeling and releasing of the total tendon of the extensor muscle, which can also achieve better results. Tennis elbow is not a big disease, but it has a great impact on working life. In the mind, “small disease is a big cure”, so as to achieve the best treatment effect in the shortest possible time.
