Ultrasound, MRI and Arthroscopic Correlation of Rotator Cuff Tears
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 3
Abstract
Introduction: Rotator cuff tears are amongst the most frequently encountered problems in the shoulder joint. Clinical assessment has limited role and radiological imaging is necessary for confirmation of diagnosis and guiding management. Aim of the research was to study the sensitivity and specificity of ultrasound and MRI as compared to arthroscopy in evaluation of rotator cuff tears. Material and methods: Ultrasound and MRI evaluation was done in clinically suspected patients of rotator cuff tear on Philips iU22 Ultrasound machine and on 1.5 Tesla GE MRI machine and was confirmed by arthroscopy. Results: The sensitivity and specificity of diagnosing partial thickness tear was 91.4% / 100% and 88.2% / 100% for ultrasound and MRI respectively. The sensitivity and specificity of MRI for diagnosing full thickness tear was 100% each and that for ultrasound was 90% and 100% respectively. Supraspinatus tendon was the most commonly injured tendon, followed by combined injury of two or more tendons. Conclusion: Our results show that ultrasound has comparable sensitivity to MRI in detection of rotator cuff tears. As ultrasound is easily available and cost effective, it can be a used as a primary screening modality in patients suspected of having rotator cuff tears. MRI provides additional information like associated labral tears. Arthroscopy remains the gold standard, however intrasubstance partial thickness tears can be missed on arthroscopy but can be diagnosed on MRI and sometimes ultrasound.
