How do you fix a Perilunate dislocation?

How do you fix a Perilunate dislocation?

The treatment choices for perilunate and lunate dislocations are closed reduction and casting, open reduction-internal fixation-ligament repair, trapeziolunate external fixation, limited wrist arthrodesis and proximal row carpectomy.

What is a Perilunate fracture?

Perilunate dislocation and perilunate fracture dislocation are injuries that involve traumatic rupture of the radioscaphocapitate (RSC) ligament, the scapholunate interosseous (SLI) ligament, and the lunotriquetral interosseous (LTI) ligament.

How is a lunate fracture treated?

The treatment of an acute, nondisplaced lunate fracture includes immobilization via a cast or an orthosis for 4 to 6 weeks. Lunate fractures that are displaced greater than 1 mm require fragment stabilization with open reduction and internal fixation (ORIF).

What is the difference between lunate and Perilunate dislocation?

A perilunate dislocation is disruption of the normal relationship between the lunate and capitate. A lunate dislocation is separation of the lunate from both the capitate and the radius. Perilunate and lunate dislocations result when great force is applied to a hyperextended wrist.

How do lunate and Perilunate dislocation differ?

The key to not confusing the two is the lateral projection:

  1. in a lunate dislocation, the radiolunate articulation is disrupted and the lunate is dislocated in a palmar direction.
  2. in a perilunate dislocation, the radiolunate articulation is maintained.

Where is the Perilunate dislocation?

Lunate/perilunate dislocations are high energy injuries to the wrist associated with neurological injury and poor functional outcomes.

Can you break your trapezium?

The trapezium is rarely injured, representing about 4 percent of all carpal fractures [1-6]. When present, trapezium fractures often occur in association with other injuries, most commonly fracture of the first (thumb) metacarpal followed by other carpal bone injuries and the distal radius [7].

Where is the trapezium bone?

At the base of the thumb is a small bone called the trapezium which, together with the metacarpal bone above, forms a joint called the carpometacarpal joint (CMCJ). Removal of the trapezium bone can reduce the pain and allow easier use of the thumb.

How do you treat a scaphoid fracture?

How are scaphoid fractures treated?

  1. Immobilization. If your break is mild and your scaphoid didn’t move far out of place (if it’s non-displaced), you might only need a splint or cast.
  2. Closed reduction.
  3. Internal fixation.
  4. Bone grafting.
  5. Can a scaphoid fracture heal on its own?

How long does a lunate fracture take to heal?

Lunate fracture: Most lunate fractures heal with placement of a spica cast for 10-12 weeks.
