Abstract
In a retrospective survey we compared the magnetic
resonance imaging (MRI) protocols with the arthroscopic
findings for triangular fibrocartilage complex
(TFCC) lesions. We found a sensitivity of 0.61 and
specificity of 0.88 for MRI. The positive predictive
value was 0.85 and the negative predictive value was
only 0.68. These values are very similar to those in
other recent surveys.
These findings and the reviewed publications all indicate
that MRI cannot replace arthrocopy. Special
coils and MRI-arthrography can significantly enhance
the specificity and the sensitivity. A negative MRI
is not an endpoint and not a contraindication for
further exploration, in particular for arthroscopy.
