Abstract
Background: The triangular fibrocartilage consists of the triangular fibrocartilage proper, the dorsal and volar radioulnar ligaments, the ulnar collateral ligament, the meniscal homo-logue, the extensor carpi ulnaris, and the ulnolunate and ulnotriquetral ligament. On magnetic resonance imaging, the TFC proper is homogeneously low in signal on all sequences. The ulnar attachment is striated and sometimes has an inter-mediate signal intensity. Ultrasound examination has wide availability, portability, low cost and no radiation. Ultrasound is used for assessing the soft tissues. The imaging capability, practicality, and dynamic component have led to ultrasound being increasingly used as a first-line investigation for all wrist soft-tissue abnormalities except for those of the intrinsic/ extrinsic ligaments and the triangular fibrocartilage complex. Musculoskeletal ultrasound sometimes does not provide enough information regarding the internal structures of the wrist to allow a final diagnosis. However, promising results have been published regarding the ultrasound examination of the triangular fibrocartilage.
Aim of Work: The aim of this study is to evaluate the diagnostic performance of both ultrasonography and MRI findings in evaluation of triangular fibrocartilage.
Patients and Methods: This study included fifty patients; 30 males, 20 females with age range from 21 to 75 years. All patients were presenting with ulnar sided wrist pain. They all were subjected to examination by both MRI and ultrasound.
Results: Statistical analysis of the results showed highly significant agreement between the two modalities in the detection of Triangular Fibrocartilage (TFCC) tear and degen-eration.
