Wrist Triangular Ligament Tear
Posted By admin On 21/06/18Injuries to the TFCC present as ulnar-side wrist pain, frequently with clicking. Torn TFCCs constitute 35% of intra-articular fractures and 53% of extra-articular fractures.
Triangular fibrocartilage complex (TFCC) injuries of the wrist affect the little finger side of the wrist. Mild injuries of the TFCC are called wrist sprain. What is a TFCC tear? The triangular fibrocartilage complex (TFCC) is a cartilage structure located on the small finger side of the wrist that, cushions and supports. The triangular fibrocartilage complex (TFCC) is a complex structure that is a major contributor to the stability of the wrist. Gross anatomy The TFCC is located on. TFCC tear explained. The Six Figure Second Income Pdf. The triangular fibrocartilage complex consists of: The triangular fibrocartilage disc. Ulna meniscus. Ulnar collateral ligament. Several carpal ligaments. Extensor carpi ulnaris tendon sheath. The function of this group of structures is to provide stability, cushioning and smooth movement at the wrist joint.
There is no correlation between ulnar styloid fractures and TFCC injuries. Patients with a torn TFCC display ulnar variance (radial shortening) that is on average 4.6 mm (vs 2.5 mm for no tear) and dorsal angulation of 24° (vs 12° for no tear). Since 1777, when DeSault's original dissertation first described DRUJ injuries, much has been written about this joint and the TFCC. As Palmer pointed out, [,, ] humans are differentiated from lower primates by a radiocarpal joint with a TFCC interposed between the ulna and carpus. [] This TFCC improves wrist functional stability and allows six degrees of freedom at the wrist—flexion, extension, supination, pronation, and radial and ulnar deviation. As interest in the TFCC evolved, open repair techniques for this structure were devised.
