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 ...
TFCC injuries causing obvious DRUJ instability can be addressed at the time of fixation. [citation needed] Prognosis varies depending on dozens of variables. If the anatomy (bony alignment) is not properly restored, function may remain poor even after healing. Restoration of bony alignment is not a guarantee of success, as soft tissue ...
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.
In 2000, the photos were rescanned at a higher resolution, yielding more than 65 gigabytes. The female cadaver was cut into slices at 0.33-millimeter intervals, resulting in some 40 gigabytes of data. The term "cut" is a bit of a misnomer, yet it is used to describe the process of grinding away the top surface of a specimen at regular intervals ...
The radial collateral ligament (external lateral ligament, radial carpal collateral ligament) extends from the tip of the styloid process of the radius and attaches to the radial side of the scaphoid (formerly navicular bone of the hand), immediately adjacent to its proximal articular surface and some fibres extend to the lateral side of the trapezium (greater multangular bone).
The ulnar collateral ligament (internal lateral ligament, ulnar carpal collateral ligament or ulnar collateral ligament of the wrist joint) is a rounded cord, attached above to the end of the styloid process of the ulna, and dividing below into two fasciculi, one of which is attached to the medial side of the triquetral bone, the other to the pisiform and flexor retinaculum.
Chondrocalcinosis can be visualized on projectional radiography, CT scan, MRI, ultrasound, and nuclear medicine. [1] CT scans and MRIs show calcific masses (usually within the ligamentum flavum or joint capsule), however radiography is more successful. [1]
Primal Pictures is a business established in 1991 that provides 3D graphic renderings of human anatomy, built using real scan data from the Visible Human Project, for use by healthcare students, educators, and medical professionals. It operates the Anatomy.tv online platform. [1]
