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 head resection?
Ulnar-head resection is commonly performed in RA because the distal radioulnar joint is more often involved in RA than in OA of the wrist. The wrist tends to deviate and subluxate toward the ulna, resulting in ulnar-head prominence and impingement, which produces significant symptoms in RA but not in OA.
What is the DRUJ?
The distal radioulnar joint (DRUJ) is part of the complex forearm articulation that includes proximal radioulnar joint (PRUJ), forearm bones, and interosseous membrane (IOM) allowing pronosupination. It is functionally and anatomically integrated with the ulnocarpal articulation of wrist.
What is a wafer procedure?
The arthroscopic wafer procedure involves debridement of the central triangular fibrocartilage complex tear, along with debridement of the distal pole of the ulna causing the impaction. Debridement of the ulna arthroscopically is taken down to a level at which the patient is ulnar neutral or slightly ulnar negative.
What is Kapandji technique?
Intrafocal (Kapandji) pinning is one available technique. The technique is based on placement of wires into the fracture site, pivoting the wires distally about 45°, then proximal advancement of the pins through cortical bone. Pins must be carefully placed between the dorsal wrist compartments.
Why is arthrodesis performed?
If you have severe arthritis pain, your doctor may suggest that you have joint fusion surgery (also called “arthrodesis”). This procedure fuses, or “welds,” together the two bones that make up your aching joint. It causes the bones to become one solid bone, and it can lessen your pain.
Where is the ulnar head located?
Wrist Joint
The lateral, distal end of the ulna is the head of the ulna. It articulates with the ulnar notch on the radius and with the triangular articular disc in the Wrist Joint.
What attaches to ulnar head?
The head is separated from the styloid process by a depression for the attachment of the apex of the triangular articular disk, and behind, by a shallow groove for the tendon of the extensor carpi ulnaris muscle. The styloid process of the ulnar varies in length between 2 mm and 6 mm.
How do you fix DRUJ?
Treatment include splinting, ORIF of fractures and repair of torn ligaments and TFCC by arthroscopy or open methods. In late presentations, instability is addressed by various techniques which have been described. DRUJ arthroplasty is emerging as a treatment in cases of arthrosis of the joint.
How do I check my DRUJ instability?
Different physical tests for the diagnosis of DRUJ instability have been described, including the Ballottement test, radius pull test, clunk test, extensor carpi ulnaris (ECU) test, and press test. The Ballottement test is considered the most reliable physical examination test for DRUJ instability.
How common is ulnar impaction syndrome?
Studies suggest that between 3 and 9% of all sports injuries involve the wrist and/or hand. Andrew Hamilton looks at ulnar impaction, one of the more common injuries to affect this region, especially among older athletes.
