What is Intercarpal arthrodesis?
What is Intercarpal arthrodesis?
intercarpal arthrodesis procedure is the scaphoidec- tomy with fusion of the capitate, lunate, hamate and. triquetrum.1 Also known as a 4-corner fusion (4CF), variants of this procedure have been described.
What is wrist arthrodesis?
Wrist arthrodesis, also known as wrist fusion, is a procedure in which the wrist joint is immobilized by fusing the radius to the carpal bones. It is a procedure used for pain relief purposes in conditions such as advanced wrist arthritis, following wrist fractures, or severe ligament injuries.
What is Intercarpal Fusion?
Four-corner fusion (4CF) is an accepted and regularly performed procedure when managing posttraumatic degenerative disorders in the wrist. This procedure consists of excision of the entire scaphoid in association with midcarpal fusion of the remaining four ulnar carpal bones (hamate, capitate, lunate, and triquetrum).
What is Capitolunate Fusion?
Limited wrist fusions have become a well-accepted surgical procedure for patients with localized arthritis of the wrist. The overriding principle is that the arthritic painful components of the joint are fused, allowing the wrist to mobilize via the intact component of the joint.
What is Kienbock’s disease?
Kienböck’s Disease. Kienböck’s disease is a condition where the blood supply to one of the small bones in the wrist, the lunate, is interrupted. Bone is living tissue that requires a regular supply of blood for nourishment. If the blood supply to a bone stops, the bone can die.
What is PRC surgery?
In cases of severe arthritis of the wrist, surgical removal of the scaphoid, lunate and triquetrum bones or proximal row carpectomy (PRC) is a well-known procedure. This procedure converts the wrist in a simple hinged joint but allows us to preserve a certain range of motion in the wrist.
Is scaphoid hand or wrist?
The scaphoid bone is one of the carpal bones on the thumb side of the wrist, just above the radius. The bone is important for both motion and stability in the wrist joint. The word “scaphoid” comes from the Greek term for “boat.” The scaphoid bone resembles a boat with its relatively long, curved shape.
Are there any cases of intercarpal arthrodesis?
In 1946, Sutro7reported 4 cases of scaphoid nonunions treated by intercarpal arthrodesis of the scaphoid fragments to the capitate. Similarly, in 1952 Helfet8reported 7 cases of scaphocapitate arthrode- sis for the treatment of scaphoid nonunions.
What happens to scaphoid fragments when arthro-Desed to the capitate?
However, when the scaphoid fragments were arthro- desed to the capitate, pain diminished and strength improved.5,7,8Intercarpal arthrodesis of the scaphoid and capitate provided pain relief, stability, and the preservation of some wrist motion.
What are the benefits of 4 corner arthrodesis?
The 4-corner arthrodesis is a motion-sparing, limited arthrodesis that reliably results in pain relief, improved grip strength, and overall high patient satisfaction with low associated nonunion and compli- cation rates. Copyright©2001 by the American Society for Surgery of the Hand
Why is the radiolunate articulation called the 4 corner arthrodesis?
This time-tested and established procedure that is commonly known as the 4-corner or 4-bone arthrodesis is based on the principle that the radiolunate articulation is often spared from degenerative changes from conditions that result in rotatory subluxations of the scaphoid.
