What is Radiocarpal dislocation?

What is Radiocarpal dislocation?

A radiocarpal dislocation (RCD) is the total loss of contact between the carpus and the radius.

Which bone is dislocated in Galeazzi fracture?

A Galeazzi fracture is a fracture of the middle to distal third of the radius. It also involves the dislocation of the distal radioulnar joint (DRUJ), which is located in between the radius and ulna at the near end of the wrist joint.

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 Perilunate dislocation?

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.

What is Radiocarpal ligament?

The palmar radiocarpal ligament (anterior ligament, volar radiocarpal ligament) is a broad membranous band, attached above to the distal end of the radius, and passing downward to the scaphoid, lunate, triquetrum and capitate of the carpal bones in the wrist.

What is SLAC wrist?

Scapholunate advanced collapse (SLAC) is a characteristic degenerative clinical wrist condition of progressive deformity, instability, and arthritis that affects the radiocarpal and mid-carpal joints of the wrist.

What nerve is damaged in Galeazzi fracture?

Galeazzi fractures are sometimes associated with wrist drop due to injury to radial nerve, extensor tendons or muscles.

How is a Galeazzi fracture treated?

How are they treated? Most Galeazzi fractures will require surgery, except possibly in a child. Surgery requires an open reduction. In this procedure, the bones are put back into place and a plate and screws are used to keep the fractured bones together.

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.

What does Perilunate mean?

When dislocation occurs in the wrist, it is typically perilunate, meaning that the bones surrounding the lunate lose their continuity with the lunate through disruption of the ligaments. Usually this involves the capitate dislocating dorsally.

What muscles do Radiocarpal joints?

Muscles acting on the radiocarpal joint Extension is mainly produced by the extensor carpi radialis longus, extensor carpi radialis brevis, and extensor carpi ulnaris muscles, with assistance from extensor digitorum. Adduction is produced by the extensor carpi ulnaris and flexor carpi ulnaris.

What does the radiocarpal joint do?

The radiocarpal joint allows proper hand movements, this includes flexion, extension, adduction, and abduction of the wrist but the supination and pronation of the hand, movements known as rotation, cannot be done by the hand as a unit or independent in relation to the forearm.
