medial tears are in the vascularized zone and a surgical repair is a treatment option whereas central tears are in the avascular zone and are typically debrided 1. TFCC, triangular fibrocartilage complex; DRUJ, distal radioulnar joint. There are two types of TFCC tear: Type 1. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. There is dorsal subluxation of the distal ulna at the sigmoid notch associated with moderate subchondral cystic changes (block long arrows) of the radius; (B) coronal proton density fat-suppressed MR image of another patient showed an ulnar-sided tear of the TFCC (solid long arrow). On the volar side, the TFC is attaching to a low signal linear structure representing the volar radioulnar ligament (vRUL). Epub 2010 Apr 1. Oneson SR, Scales LM, Timins ME, Erickson SJ, Chamoy L. MR imaging interpretation of the Palmer classification of triangular fibrocartilage complex lesions. Learn how to see all the different components of the TFCC and how to find them on MRI. The current likely hierarchy of techniques for wrist imaging with respect to depiction of tears and articular cartilage surface is suggested. This approach further trialed the MRI dataset of a patient with minor radiological TFCC alterations but persistent pain. Non-surgical treatment. Patient-Reported Outcomes following Arthroscopic Triangular Fibrocartilage Complex Repair. Atypical tear and limitations of MRI in diagnosis of TFCC tear are also discussed. Indian J Orthop. Triangular fibrocartilage complex (TFCC) injuries may be traumatic or degenerative in nature. After contrast injection into the joint, the joints are well distended including the prestyoid recess (block curved arrow) and DRUJ (solid curved arrow). ECU, extensor carpi ulnaris; TFCC, triangular fibrocartilage complex. TFCC degenerations are intrinsically high signal not extending to the articular surface 3. This MRI arthrogram shows a tear in the TFCC, allowing the dye (white fluid on MRI) to leak out of the joint. It has an elongated triangular shape with the apex pointing at the radius 5 and consists of the triangular fibrocartilage disc proper along with 1,2:. (1996) Radiographics : a review publication of the Radiological Society of North America, Inc. 16 (1): 97-106. Yamamoto M, Koh S, Tatebe M, Shinohara T, Shionoya K, Hirata H, Nakamura R. J Orthop Sci. (A) The TFC (asterisk) is concave in appearance on a sagittal view. (2017) Quantitative imaging in medicine and surgery. Luckily there is an easy, inexpensive test Patients may present with ulnar-sided wrist pain, that is exacerbated by supination, pronation and/or ulnar deviation 5. Injuries range from mild to severe, but all can disable the wrist. (A) Coronal proton density fat-suppressed MR image shows atypical tear of the TFC centrally located and extending from the distal surface (block arrow) to the foveal attachment (solid arrow). This site needs JavaScript to work properly. The purpose of this article is to review the anatomy of TFCC, state of art MRI imaging technique, normal appearance and features of tear on MRI according to the Palmar's … On the volar side, the TFC is attaching to the volar radioulnar ligament (vRUL) (long solid arrow) and more distally through the ulnotriquetral ligament (short solid arrows).
