Ganglions of the wrist and fingers are a common problem. They are the most common soft tissue lump in the hand. A ganglion arises from a joint or a tendon and occur most frequently over the back of the wrist, but may also occur at the front of the wrist and just behind the fingernail. Often very solid they can be mistaken for bony lumps. Those associated with the fingernail can cause fingernail deformity.
Hitting the ganglion with a bible is no longer recommended. Aspiration of wrist ganglions can resolve up to 50% of wrist ganglions but sometimes surgery can be required. Even so, up to 10% of ganglions will recur after surgery.
