title: Tears of the triangular fibrocartilage of the wrist: MR imaging.
abstract: Magnetic resonance (MR) imaging of the wrist was performed in 35 patients with specific complaints of pain and soft-tissue swelling in the medial side of the wrist. Twenty of the 35 subsequently underwent surgery. In 14 of the patients who underwent surgery, a diagnosis of triangular fibrocartilage (TFC) tear was made at MR imaging; in 13 of the 14 the tear was confirmed by surgical findings. In the six patients with an MR diagnosis of an intact TFC, surgical findings confirmed the diagnosis. These patients were operated on for an abnormality in the vicinity of the TFC (avascular necrosis, ganglion cyst, xanthoma). On the basis of findings from the 20 patients with surgical correlation, the accuracy of MR imaging in the detection of TFC tears was 95%. MR imaging is a valuable noninvasive method in the study of pathologic conditions of the TFC.
