Abstract

The ability of single-injection radiocarpal arthrography and magnetic resonance imaging (MRI) to detect full-thickness tears of the triangular fibrocartilage were compared with wrist arthroscopy in 102 patients with wrist pain. The sensitivity of arthrography was 85%, and of MRI was 73%. Specificity was 100% for arthrography and 72% for MRI. Accuracy was 92% for arthrography, and 73% for MRI. Although future advances in MRI technology will probably improve its usefulness, single-injection wrist arthrography currently is superior to routine MRI for the detection of full-thickness triangular fibrocartilage tears.
