The diagnostic accuracy of X-ray arthrography for triangular fibrocartilaginous complex injury: a systematic review...

The purpose of this study was to evaluate the diagnostic test accuracy of X-ray arthrography in the detection of TFCC tear. Both published and unpublished databases were searched from their inception to August 2010. All studies comparing the diagnostic accuracy of X-ray arthrography (index test) to arthroscopy (reference standard) for patients with suspected TFCC tears were included in this review. Twelve studies assessing 430 patients (430 wrists) satisfied the eligibility criteria and were included. X-ray arthrography presented with a pooled sensitivity of 76.2% and specificity of 92.5% for the detection of complete TFCC tear. The triple-compartment injection X-ray arthrography was superior to the single-compartment injection technique. To conclude, the diagnostic test accuracy of X-ray arthrography is limited. Neither the single- nor the triple-compartment injection arthrography method is acceptable, given their reported low sensitivities. Further evaluation of the diagnostic test accuracy of Magnetic Resonance Arthrography and Magnetic Resonance Imaging is therefore warranted.
