What is distal ulna resection?
What is distal ulna resection?
Distal ulnar resection is performed by fusing the head of the ulna to the sigmoid notch of the distal radius with a cancellous screw, resulting in distal radioulnar joint fusion. This is called the Sauve-Kapandji procedure (see image below).
How do you reduce distal ulna dislocation?
Closed reduction by forceful hyperpronation of the wrist while pulling the ulnar head in dorsal direction under sedation is the treatment of choice in emergency, and surgery is required only when the dislocation persists or if a DRUJ instability remains.
What is a darrach resection?
Darrach’s procedure or distal ulna resection is a surgical technique for the surgical removal of the head of ulna. It is performed in cases of radial–ulnar joint pain and instability.
What is Sauve Kapandji procedure?
In 1936, Sauvé and Kapandji described a procedure that included an arthrodesis across the distal radioulnar joint and created a pseudarthrosis of the ulna, proximal to the fusion, to restore pronation and supination.
What is ulnar shortening surgery?
Background The purpose of ulnar shortening osteotomy is literally to shorten the ulna. It can tighten the triangular fibrocartilage complex (TFCC), ulnocarpal ligaments, and interosseous membrane. Nowadays, this method is used to treat ulnar-sided wrist pain, for which we have also started to use a treatment algorithm.
What does it mean when a joint is distal?
: a pivot joint between the lower end of the ulna and the ulnar notch on the lower end of the radius that permits rotation of the distal end of the radius around the longitudinal axis of the ulna. — called also inferior radioulnar joint.
Is the distal radioulnar joint in the elbow?
The distal radioulnar joint is a synovial joint between the distal ends of the radius and ulna. This is a uniaxial pivot joint that allows the movements in one degree of freedom; pronation-supination….Distal radioulnar joint.
| Type | Synovial pivot joint; uniaxial |
|---|---|
| Innervation | Anterior and posterior interosseous nerves |
What is an ulnar shortening osteotomy?
Ulnar shortening osteotomy is literally a procedure that shortens the ulna, which is the rationale for its use in ulnocarpal impaction syndrome. 31. Ulnar variance affects the load distribution of the wrist. Larger ulnar variance increases the load on the ulnar carpus.
