Lump or bump on the fingers, hand, or wrist

A lump or bump on a finger, hand, or wrist may have many causes.

  • A soft, rubbery bump on the front or back of your wrist may be a ganglion. A ganglion is not serious and can be left alone unless it is painful or interferes with normal activity.
  • A hard bump on the palm of the hand may be caused by Dupuytren's disease.
  • Bumps around the joints may be caused by osteoarthritis, rheumatoid arthritis, or a cyst that is filled with mucus (mucinous cyst).
  • A tender bump (nodule) on the palm may occur near a trigger finger or trigger thumb. The bump may appear to move when you bend or straighten your finger or thumb.
  • Tumors, both noncancerous or cancerous, can develop on a finger, hand, or wrist.
  • A lump or bump may develop after an injury.

Treatment depends on the cause of the lump or bump.

Avascular Necrosis (Osteonecrosis)

Avascular necrosis (AVN), also called osteonecrosis, aseptic necrosis, or ischemic bone necrosis, is a condition that occurs when there is loss of blood to the bone. Because bone is living tissue that requires blood, an interruption to the blood supply causes bone to die. If not stopped, this process eventually causes the bone to collapse. Avascular necrosis most commonly occurs in the upper leg. Other common sites are the upper arm, knees, shoulder, and ankles.
