title: MRI versus arthroscopy in the diagnosis of scapholunate ligament injury.
abstract: In a prospective study 103 patients with clinically or radiologically suspected tears of the scapholunate interosseous ligament were investigated with magnetic resonance imaging (MRI) and wrist arthroscopy. MRI was performed with the conventional technique in 72 cases and after intravenous injection of contrast medium in the remaining 31 patients. The correct diagnosis was made by MRI in 75% of cases and its overall sensitivity and specificity were 63% and 86% respectively. There was no statistical difference in the accuracy of MRI for acute or chronic tears and the use of intravenous contrast medium did not improve its accuracy. In conclusion, MRI is not recommended for the diagnosis of scapholunate ligament injury.
