Ganglion Cysts

Ganglion Cyst Surgery Manhattan | Ganglion Cyst Surgery New York CityWhat are they?

Ganglion cysts are very common lumps within the hand and wrist that occur adjacent to joints or tendons. The most common locations are the top of the wrist (see Figure 1), the palm side of the wrist, the base of the finger on the palm side, and the top of the end joint of the finger. The ganglion cyst often resembles a water balloon on a stalk (see Figure 2), and is filled with clear fluid or gel. The cause of these cysts is unknown although they may form in the presence of joint or tendon irritation or mechanical changes. These cysts may change in size or even disappear completely, and they may or may not be painful. These cysts are not cancerous and will not spread to other areas.

How are they diagnosed?

The diagnosis is usually based on the location of the lump and its clinical appearance. They are usually oval or round and may be soft or very firm. Cysts at the base of the finger on the palm side are typically a very firm, pea-sized nodule that is tender to applied pressure, such as when gripping. Light will often pass through these lumps (trans-illumination) and this can assist in the diagnosis. Your physician may request x-rays in order to investigate problems in adjacent joints; cysts at the end joint of the finger frequently have an arthritic bone spur associated with them.

Treatment can often be non-surgical. In many cases, these cysts can simply be observed, especially if they are painless. If the cyst becomes painful, limits activity, or is cosmetically unacceptable, other treatment options are available. The use of splints and anti-inflammatory medication can be prescribed in order to decrease pain associated with activities. An aspiration can be performed to remove the fluid from the cyst and decompress it. This requires placing a needle into the cyst, which can be performed in most office settings. If non-surgical options fail to provide relief or if the cyst recurs, surgical alternatives are available. Surgery involves removing the cyst along with a portion of the joint capsule or tendon sheath (see Figure 3). In the case of wrist ganglion cysts, both traditional open and arthroscopic techniques may yield good results. Surgical treatment is generally successful although cysts may recur. Your surgeon will discuss the best treatment options for you.

Trigger Finger

What is it?

Trigger Finger Surgery Manahttan | Trigger Finger Surgery New York CityStenosing tenosynovitis, commonly known as "trigger finger" or "trigger thumb", involves the pulleys and tendons in the hand that bend the fingers. The tendons work like long ropes connecting the muscles of the forearm with the bones of the fingers and thumb. In the finger, the pulleys are a series of rings that form a tunnel through which the tendons must glide, much like the guides on a fishing rod through which the line (or tendon) must pass. These pulleys hold the tendons close against the bone. The tendons and the tunnel have a slick lining that allows easy gliding of the tendon through the pulleys (see Figure 1).

Trigger finger/thumb occurs when the pulley at the base of the finger becomes too thick and constricting around the tendon, making it hard for the tendon to move freely through the pulley. Sometimes the tendon develops a nodule (knot) or swelling of its lining. Because of the increased resistance to the gliding of the tendon through the pulley, one may feel pain, popping, or a catching feeling in the finger or thumb (see Figure 2). When the tendon catches, it produces inflammation and more swelling. This causes a vicious cycle of triggering, inflammation, and swelling. Sometimes the finger becomes stuck or locked, and is hard to straighten or bend.

What causes it?

Causes for this condition are not always clear. Some trigger fingers are associated with medical conditions such as rheumatoid arthritis, gout, and diabetes. Local trauma to the palm/base of the finger may be a factor on occasion, but in most cases there is not a clear cause.

Trigger Finger Treatment Manhattan | Trigger Finger Treatment New York CitySigns and symptoms

Trigger finger/thumb may start with discomfort felt at the base of the finger or thumb, where they join the palm. This area is often tender to local pressure. A nodule may sometimes be found in this area. When the finger begins to trigger or lock, the patient may think the problem is at the middle knuckle of the finger or the tip knuckle of the thumb, since the tendon that is sticking is the one that moves these joints.


The goal of treatment in trigger finger/thumb is to eliminate the catching or locking and allow full movement of the finger or thumb without discomfort. Swelling around the flexor tendon and tendon sheath must be reduced to allow smooth gliding of the tendon. The wearing of a splint or taking an oral anti-inflammatory medication may sometimes help. Treatment may also include changing activities to reduce swelling. An injection of steroid into the area around the tendon and pulley is often effective in relieving the trigger finger/thumb.

If non-surgical forms of treatment do not relieve the symptoms, surgery may be recommended. This surgery is performed as an outpatient, usually with simple local anesthesia. The goal of surgery is to open the pulley at the base of the finger so that the tendon can glide more freely. Active motion of the finger generally begins immediately after surgery. Normal use of the hand can usually be resumed once comfort permits. Some patients may feel tenderness, discomfort, and swelling about the area of their surgery longer than others. Occasionally, hand therapy is required after surgery to regain better use.
