It can be injury, excessive strain (especially thumb, hand, elbow and finger), osteoarthritis, some immune diseases and even infection. Some occupations that require repeated joint strain for a long time, such as typists, keyboard players, instrumental musicians, cargo handling or industries that require long-term computer operation, will cause or aggravate this disease. The common involved parts are wrists, fingers and shoulders. Women and diabetics are more likely to get this disease. Patients will feel joint pain and morning stiffness. Usually, the feeling of joint stiffness in the morning is the most obvious after getting up, but the symptoms of frequent activity will not be obviously relieved, and the affected joint will swell or even bounce, and the joint activity will be damaged.

Tenosynovitis of flexor tendon mostly occurs in thumb, ring finger, index finger, middle finger and elbow. Finger flexion and extension dysfunction is particularly obvious when you wake up in the morning, and it can be alleviated or disappeared after the activity. Pain sometimes spreads to the wrist. The flexion of metacarpophalangeal joints may be tender, and sometimes thickened tendon sheaths and pea-sized nodules may be touched. When bending the affected finger, it suddenly stays in the semi-flexion position, and the finger can neither be straightened nor flexed, like being suddenly "stuck", and the pain is unbearable. With the help of the other hand, the finger can move again, producing the action and snapping sound similar to a gun wrench, so it is also called "trigger finger".

block therapy

Can relieve early tenosynovitis, and seal it once a week. The general blocking therapy is harmful to local tissues and easy to relapse. Severe patients can choose surgery. Do finger flexion and extension exercises early after operation to prevent tendon adhesion, and avoid physical labor within 1 month after operation.

Surgical therapy

After operation, choose appropriate splint for fixation. Small needle knife release or tendon amputation is feasible when non-surgical treatment is ineffective. Cut at the transverse palmar striation, separate with vascular forceps, and reach the tendon sheath to avoid damaging the digital vascular nerve bundle.

Puncture therapy

After local anesthesia, puncture with a thick needle, draw out the cystic fluid, inject it, and then pressure bandage it. Hormone drugs can have side effects on the body.

For cases with short course of disease and mild symptoms, conservative treatment can be implemented, including using braces to properly brake the thumb, changing the activities and habits that induce diseases, reducing cold stimulation, local hot compress, physical therapy, and external application of drugs.

needle therapy

Take the points of Yangxi, Yangchi, Hegu, Quchi, Yangque, Shousanli, Lieque, Pianli and Ashi on the affected side of the patient, and routinely disinfect the skin. Take Ashi point, the tender point, and adopt the method of encircling needling. After acupuncture, the methods of tonifying and purging will be implemented. Moxibustion at Yangxi, Lieque and Yangchi points, 65438 0 times a day.

Massage method

Massage adopts point, press, push, knead, roll, dial and knead local and distal acupoints, and the doctor massages the styloid process of radius and its upper and lower parts with his thumb 15 minutes. By using the above method, the clinical observation shows that the effect is satisfactory.
