Lunate Dislocation

Lunate Dislocation

is a type of injury at the wrist joint. When one of the small bones of our wrist joint, called the carpal bone comes out of its normal position, it is called dislocation of the lunate. Generally a fall from a height or a road accidents commonly cause this condition.

Common Symptoms Of Lunate Dislocation:

  • Noticeable pain in the palm and the wrist Swelling in the hand
  • Restricted motion in the wrist and the hand
  • Tingling sensation and numbness in the fingers
  • The common risk associated with the dislocation of the lunate is the acute initiation of the Carpal Tunnel Syndrome, which is affected by the pinching of the median nerve. When the dislocated lunate bone pushes into the carpal tunnel, it pinches the median nerve.

Diagnosis Of Lunate Dislocation:


regular X-ray test

is enough to identify the dislocated lunate bone on our wrist joint. A slight rotation is done on the wrist for the perfect visibility of the affected bone. But people with sever pain and injury find it very difficult and very uncomfortable. If further diagnosis is required then,

a CT scan or an MRI

can be ideal.

Treating Dislocation Of Lunate:


the bone back to its original place is most important.

Surgical treatment

is advisable while in few cases it can be done without any surgery in the emergency room. But proper healing always require surgical methods to stabilize the bones. During surgery, pins may be used coming through the skin to held the bones in place which may be removed later. Release in carpal tunnel may be done if symptoms of carpal tunnel syndrome persists. The surgeon should also address other fractures or effects on the ligaments may be associated with the lunate dislocation during the surgery.

Complications after a Lunate Dislocation:

  • Wrist arthritis
  • Instability of the affected wrist joint
  • Persistent pain.

Duration Of Cure:

A complete cure of the dislocation of the wrist bone would take a

minimum of 6 month

s or may be longer in few extreme cases.
