Tennis elbow, i.e. inflammation of the epicondyle of the humerus, is a chronic inflammatory disease. As an important part of non-surgical treatment, the principle of wearing a brace is to reduce inflammation and relieve pain by restricting the movement and rotation of the muscles of the forearm and avoiding a series of actions that aggravate the chronic injury such as stretching of the wrist and clenching of the fist. Splints, slings, wrist straps and other supports are available. 1. Splint: In the acute stage of inflammation, when the symptoms are severe, it is necessary to wear a 30° splint in the extended position of the wrist to immobilize the whole wrist, and the distal part of the limb can move freely. 2. Sling and wrist strap: because of the soft material, often need to cover the most elevated forearm muscles and appropriate pressure to make a fist, stretching wrist activities feel obvious effort is appropriate, pay attention to avoid the ring tie too tight to affect the blood supply. The specific use of the method of consultation with a doctor, more safe and effective.
