Abstract

[Indexed for MEDLINE] 14. Semin Musculoskelet Radiol. 2008 Dec;12(4):359-77. doi: 10.1055/s-0028-1100642. Epub 2008 Nov 18. Ligamentous injuries of the wrist. Tanaka T(1), Ogino S, Yoshioka H. Author information: (1)Department of Orthopedic Surgery, Kikkoman General Hospital, Chiba, Japan. The purpose of this review is to summarize ligamentous injury of the wrist. Triangular fibrocartilage complex (TFCC), scapholunate ligament (SLL), and lunotriquetral ligament (LTL) are crucial to wrist stability. Damage to these ligaments causes changes in bone alignment and altered motion pattern. This may cause pain and eventually osteoarthritis. Imaging techniques of the wrist include conventional arthrography, computed tomography (CT) arthrography, conventional magnetic resonance imaging (MRI), and MR arthrography. Especially, MRI plays an important role in the assessment of TFCC, SLL, and LTL. Therefore, special attention is drawn to normal and abnormal MR imaging appearance of these ligaments in this review. Variety of treatment options dependent on classification of TFCC and ligamentous injury as well as role of imaging in the patient treatment are also discussed. DOI: 10.1055/s-0028-1100642
