The pathological changes of stenosing tenosynovitis of the fingers and wrists and tennis elbow are chronic aseptic inflammation of the tendon sheath caused by prolonged activity and friction, which is a non-infectious inflammation that often occurs in middle-aged and elderly women who have been straining and working hard for a long time. For stenosing tenosynovitis (popping finger, popping thumb, radial stenosing tenosynovitis, tennis elbow, cricket elbow, etc.) treatment methods: 1, absolute rest, avoid all upper limb activities (except for daily activities that I must personally carry out, the rest of the activities should be avoided). Absolute rest is the prerequisite for all treatment, but most patients have difficulty in doing this standard, so the treatment is not effective. 2.Heat compress or hot water bath in warm water at 37-40℃ for 20-30 minutes each time, 3-5 times a day, to relieve patients’ pain symptoms to different degrees. 3.Anti-inflammatory and analgesic drug treatment, such as celecoxib, loxoprofen sodium tablets and other painkillers, but should not be used for a long time because of side effects such as gastrointestinal tract. Local topical painkillers such as diclofenac sodium cream can also be applied. Local injection of corticosteroids and lidocaine, which is often referred to as “closed therapy”, can temporarily relieve patients’ pain symptoms, but the pain symptoms are prone to recurrence. 5.If the symptoms are serious or non-surgical treatment is ineffective, surgery is needed. The surgical method is often to cut open the narrow tendon sheath, but there is a possibility of tendon adhesions after surgery, so it is easy to recur after surgery.
