摘要

Background

Trauma-related rotator cuff tears are a common cause of shoulder pain and functional impairment, particularly in younger and middle-aged adults. Accurate imaging is essential for appropriate diagnosis and management. Magnetic resonance arthrography (MRA) is considered superior for evaluating rotator cuff pathology and serves as a reference standard for comparison.

Objective

The aim of this study was to assess the diagnostic accuracy of magnetic resonance imaging (MRI) and ultrasonography in detecting trauma-related rotator cuff tears among adults aged 18–52 years, taking MRA as the gold standard. The study also aimed to evaluate the agreement between imaging modalities within this specific cohort.

Method

A total of 60 shoulders with rotator cuff injuries that were scanned for MRA, MRI, and ultrasound were included in the study. Frequency analysis, cross-tabulation, sensitivity, specificity, and kappa statistics were used to assess the level of agreement between imaging techniques. Paired comparisons between imaging modalities were analyzed using McNemar’s test to assess differences in diagnostic performance.

Results

Overall, MRI showed a higher proportion of true-positive detections for supraspinatus (SSP) tears (30.0%) compared to ultrasonography (28.3%), while ultrasonography demonstrated a higher detection rate for subscapularis (SSC) tears. The a sensitivity of MRI for detecting SSP tears was 81.2% and 75% for SSC tears. Age- and gender-based analysis revealed that ultrasonography showed higher true-positive detection in younger patients, whereas MRI showed greater sensitivity in older patients. Kappa statistics demonstrated substantial agreement between MRI and MRA (κ = 0.892) and moderate agreement between ultrasonography and MRA (κ = 0.751).

Conclusion

Ultrasonography and MRI are reliable for diagnosing trauma-related rotator cuff tears in adults aged 18–52 years. Within this age range, MRI performs better in older patients, while ultrasonography is more effective in younger individuals; MRA remains the reference standard.
