Description:
We reviewed a series of 50 consecutive wrist arthroscopy patients who had been investigated pre-operatively by direct magnetic resonance arthrography and calculated the sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of magnetic resonance arthrography in detecting full-thickness triangular fibrocartilage complex tears, intrinsic carpal ligamentous lesions, wrist synovitis and chondral lesions in the radiocarpal joint. The sensitivities of magnetic resonance arthrography in detecting central triangular fibrocartilage complex tears, peripheral triangular fibrocartilage complex tears, scapholunate ligament tears, lunotriquetral ligament tears, dorsal synovitis and radiocarpal chondral lesions were 89%, 63%, 71%, 100%, 32% and 65%, respectively, and its specificities in detecting these lesions were 91%, 98%, 89%, 94% 94% and 97%, respectively. This study suggests that single compartment direct wrist magnetic resonance arthrography can provide high diagnostic accuracy for full-thickness triangular fibrocartilage lesions, intrinsic carpal ligament tears and chondral lesions in the radiocarpal joint, but that it is much less accurate in diagnosing synovitis of the radiocarpal joint.
