How to repair the tenosynovial cyst of extremities joint

Orthopedics is the most common is the tenosynovial cyst of limbs, wrist, finger and dorsum of foot are high incidence areas, mostly due to the friction of tendons, occurring in the buttocks called ischial tubercle cyst, the mass behind the knee joint called popliteal fossa cyst, these are special terms.

Tendon sheath cyst is a benign mass containing gelatinous mucus that occurs near the articular capsule or tendon sheath and has the highest incidence of hand disease.

The cause of the disease is unknown. At present, it is mainly believed that degenerative mucinous degeneration or local chronic strain of connective tissue on articular capsule, ligament and tendon sheath are caused by local malnutrition. Part of it is related to trauma.

1、Local swellings on the dorsal wrist, volar side or dorsum of the foot show slow growth with little pain or discomfort. The median nerve or ulnar nerve may be compressed and the corresponding sensory and motor disorders may occur in individuals with carpal canal or palmar thenar hypothalamus.

2、The tumors are hemispherical, pea to thumb size, generally no more than 2 cm, smooth and plump surface, no adhesion with the skin, hard touch, elastic, can have cystic sexuality, fixed base, pressure with acid swelling or pain.

1、Hemispherical cystic masses with smooth surface and high tension appeared in dorsal wrist, volar or dorsal foot.

2、The tumors grew slowly with soreness or pain, and the base was fixed.

3、X-ray photographs showed no changes in the bones and joints.

1、The tenosynovial cyst can disappear spontaneously, but for a long time.

2、Superficial cysts can be crushed, broken, squeezed or broken by needling. They can be cured when they are absorbed by themselves, but they are prone to recurrence.

3、Under local anesthesia, puncture with a thick needle, drain the gelatinous fluid as far as possible, inject triamcinolone acetonide injection about 5-10 mg, pressure bandage, once a week, 2-3 times in a row, the recovery, often recurrence.

4、Surgical treatment is the best. Surgery must carefully remove all the wall of the capsule, together with some normal tendon sheaths, aponeuroses and other tissues around it. Few recurrences occurred after operation. Relapsed patients can be resected again.

1、The disease generally does not require medical treatment. For intracapsular injection, hydrocortisone acetate or prednisolone can be used.

2、For those who need surgical treatment, appropriate antibiotics should be selected after operation. Some hospitalized patients also need to be supplemented with fluids and so on.

1、Do not activate the wrist vigorously, avoid overactive wrist work, avoid cold water stimulation, in order to avoid aggravating symptoms.

2、Usually it can be protected with wrist guard to relieve symptoms.
