Tennis elbow, also known as “humeral epicondylitis”, is a common disorder in sports medicine and orthopedic clinics. Tennis elbow is mostly caused by long-term strain, repeated stretching and stimulation of the starting point of the wrist extensor muscles, resulting in partial tears or localized synovial thickening or bursitis, and other factors. Tennis elbow is not exclusive to athletes, but can be caused by people who repeatedly move their forearms with force, such as housewives, typists, painters, plasterers, hairdressers and computer people, and is also a common patient in hospital outpatient clinics. Predisposing symptoms Tennis elbow can be triggered for the first time by sudden improper force on the elbow, but it is mostly of slow onset, with gradual onset of unidirectional force pain. The common clinical symptoms are: pain or severe pain in the elbow when picking up heavy objects, scrubbing laundry, twisting towels or carrying pots and pours water, sweeping the floor, and pulling the covers in bed. The pain can be mild and vague, but in severe cases, the pain can be persistent and the arm can be weak, even dropping the object. When the doctor examines the patient, he or she may find pressure pain in the epicondyle, and when the patient makes an upward movement of the wrist, the examiner applies resistance and pain occurs near the humeral epicondyle. If you have tennis elbow, you don’t have to worry too much about it. If you have mild symptoms, you can get rid of it naturally. If there are recurrent episodes of persistent pain, weakness, or even if something in your hand suddenly falls to the ground, you should go to the hospital to see a doctor. Commonly used treatment methods are physical therapy and medication. 1. Acute phase: ① Put a small ice cube in a plastic bag and place it on the painful area, then wrap it up with an elastic bandage for 20 minutes each time. Repeatedly apply and elevate the affected part. ②Local braking and rest. 2, chronic phase: In addition to local braking and rest, protection, physical therapy, pressure massage and oral anti-inflammatory drugs, the main treatment is local closure. Drug closure method of treatment should be noted: ① injection should pay attention to the tip of the needle to reach the bone surface or lesion, first longitudinal stripping, and then transverse stripping, the patient has a strong sense of acid, swelling needle, inject the drug into the periosteum or under the local scar. To avoid drug injection into the tendon or under the skin. In order to avoid focal necrosis of the tendon or skin. The number of closure should not be too many, 2 – 3 times is appropriate, each closure interval of 7 – 14 days, such as ineffective need to choose other methods. Combination of prevention and treatment Tennis elbow is prone to recurrent attacks, so we should insist on the combination of prevention and treatment, and all actions that are not conducive to the recovery of the disease should be reduced and avoided. 1.When playing tennis or badminton, choose a light, flexible and good quality racket to reduce the burden on your arm. 2.When buying groceries, housewives should try to use carts and less baskets. Carry pots, pour water, wring clothes and hand-held heavy objects to pay attention to wrist posture, not dorsiflexion. 3.When using a mop to mop the floor, the legs are slightly bent, and the strength of the waist and legs should be used to drive the shoulders and arms, rather than just using the strength of the arms to drag. 4.If you have symptoms, you should reduce the workload as much as possible to avoid deterioration.
