Arthroscopic image of a central triangular fibrocartilage complex (TFCC) tear. X-ray: X-rays of the wrist are made in two directions: posterior-anterior (PA) and lateral. Radiographs are useful to diagnose or rule out possible bone fractures, a positive ulnar variance or osteoarthritis. The TFCC is not visible on an X-ray, regardless of its ...
Both stages of TFCC tears are treatable with an arthroscopic intervention, although the degenerative stage is operated according to the "Arthroscopic wafer procedure". [3] In this procedure, the surgeon debrides the TFCC and a limited part of the ulnar head. If the patient has a Class 1 TFCC tear, a different arthroscopic technique is used.
The TFCC is a cartilage and ligament complex in the wrist that is important for stability and function. If torn, it can result in pain, catching and instability.
There is an increased risk of interosseous intercarpal injury if the ulnar variance (the difference in height between the distal end of the ulna and the distal end of the radius) is more than 2mm and there is fracture into the wrist joint. [5] Triangular fibrocartilage complex (TFCC) injury occurs in 39% to 82% of cases.
X-ray images indicate scapholunate ligament instability when the scapholunate distance is more than 3 mm, which is called scapholunate dissociation. [7] A static scapholunate instability is generally readily visible, but a dynamic scapholunate instability can only be seen radiographically in certain wrist positions or under certain loading conditions, such as when clenching the wrist, or ...
Alexander hoped to avoid surgery, telling reporters he didn't believe the PCL tear was a season-ending injury. But the knee hasn't recovered after weeks of rest and non-contact practice.
Tommy Lazzaro, a Special Forces soldier who previously played quarterback for Central Michigan University, has died. He was 27. Lazzaro was at a hunting location in Eglin Air Force Base in Walton ...
Ulnar impaction syndrome is a painful condition of excessive contact and wear between the ulna and the carpus with an associated is a degenerative tear of the TFCC. Positive, neutral, and negative ulnar variance. Relationship between radial length and ulnar variance. Radial length is the measure from distal ulna to radial styloid process.
