Ganglion cysts are usually small, painless and do not require treatment unless they press on a nerve and cause pain, tingling or numbness, explains Mayo Clinic. The treatment of symptomatic ganglion cysts in the wrist includes immobilization, aspiration, and surgery.
Movement usually increases the size of a ganglion cyst and some doctors recommend immobilization of the affected area until the cyst shrinks, according to Mayo Clinic. During an aspiration procedure, the doctor injects an enzyme into the cyst to make its jellylike contents easier to remove with a syringe. The cyst is drained with a needle and may be injected with a steroid to prevent recurrence.
Surgery is recommended when all other procedures fail to relieve the symptoms of a ganglion cyst, suggests Mayo Clinic. It involves removal of the cyst and the stalk, which may be attached to the tendon or joint. The risks of surgery include injury to the surrounding nerves, blood vessels, and tendons.
A ganglion cyst is a sac-like swelling on top of a joint or a tendon, filled with a jellylike material, explains eMedicineHealth. The cysts commonly appear in the back of the hand, at the wrist joint, and on the palm side of the wrist. Less common sites include the base of the fingers, on the palms, the fingertips, outside of the knees and ankles, and the on top of the foot.
