Abstract

Objective

The objective of this study was to evaluate ultrasound as a diagnostic tool for investigating scapholunate and lunatotriquetral ligamentous and triangular fibrocartilage (TFC) tears. Ultrasound findings were compared to conventional arthrogram findings, as the reference gold standard.

Design and patients

In total 26 patients, 17 males and 9 females ranging in age from 17 to 35 (mean age, 34), were evaluated on referral for investigation of wrist pain. All patients were examined by high resolution ultrasound, using a 9–13 MHz transducer. All wrist ultrasound examinations were also compared to conventional tricompartmental arthrography, as the diagnostic gold standard reference.

Results

All ten scapholunate tears confirmed on arthrography were detected on ultrasound. Two of 8 lunatotriquetral and 7 of 11 TFC tears were correctly diagnosed on ultrasound. Sensitivity of ultrasound diagnosis ranged from 25% for lunatotriquetral tears to 100% for scapholunate tears. No false positive results were recorded for any of the three examined structures.

Conclusion

The study results suggest that sonography is accurate for scapholunate tears, but is not accurate for evaluation of lunate-triquetral tears. It has intermediate accuracy for triangular fibrocartilage tears.
