Ganglion cysts are the most common lumps found in the hand and wrist. They are generally found on the top of the wrist, on the palm side of the wrist, or at the end joint of a finger. They arise from the capsule of a joint or the sheath of a tendon, and compose of a sac filled with thick, clear, mucus-like fluid. Their cause remains unknown. Most of the time, they are harmless and will often disappear in time. However, because the fluid-filled sac puts pressure on nerves that pass through the joint, some ganglion cysts may become painful, especially with constant, repetitive use of the hand. Their appearance may also be unsightly.
Non-surgical treatment such as immobilisation or aspiration (needle drainage of cyst fluid) is associated with a high rate of recurrence. The goal of surgery to remove a ganglion cyst aims at removing the cyst in one piece as well as the source of the cyst. This may require removal of a portion of the joint capsule or tendon sheath from where the cyst arises. The surgery is performed on an outpatient basis.
