What is Radiocarpal dislocation?
Introduction. Radiocarpal dislocations (RCD) and fracture-dislocations (RCFD) are rare (0.2% of dislocations) but severe injuries that occur following significant wrist trauma [1]. They are characterized by a complete or partial loss of contact between the carpus and the distal articulating surface of the radius [2].
Which is the most commonly involved nerve in a case of lunate dislocation?
Lunate dislocation is an uncommon injury occurring in young adults due to high-energy trauma. The volar displacement of the bone may result in compression of the median nerve within the carpal tunnel and is an uncommon cause of entrapment neuropathy.
Why is lunate most commonly dislocated?
Lunate dislocations typically occur due to a fall on an outstretched hand (or during a motor vehicle injury) where there is forceful dorsiflexion of the wrist 3. There is injury of all of the perilunate ligaments, most significantly the dorsal radiolunate ligament.
What is a lunate dislocation?
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. They usually result from a fall on an outstretched hand or occur in a motor vehicle crash.
What carpal bone is most commonly dislocated?
Two of the carpal bones are commonly dislocated:
- The capitate (which is the largest bone in the hand, located in the middle of the lower palm)
- The lunate (which is located between the capitate and the end of the ulna)

What is the worst type of wrist fracture?
