MRI likely useful to detect full-thickness rotator cuff tears — 5 points

In a study published in the Journal of Shoulder and Elbow Surgery, research indicated non-contrasted MRI had low sensitivity and high specificity for the detection of full-thickness tears of the biceps tendon, as well as high sensitivity for the instability diagnosis for the long head of the biceps.

Researchers prospectively collected surgical data on 183 patients who underwent arthroscopic rotator cuff surgery for impingement syndrome, rotator cuff tears and also those without bicep disease from 2003 to 2014.

 

Here are five points:

 

1. Results showed the sensitivity of MRI detecting partial-thickness bicep tears was 0.27 and the specificity was 0.86.

 

2. Complete tears of bicep tendon had a sensitivity for MRI detection of 0.54 and a specificity of 0.98.

 

3. For biceps subluxation/dislocation, sensitivity was 1.00 and specificity was 0.83.

 

4. The area under the receiver operating characteristic curves was 0.57 in partial tears, and 0.92 for instability.

 

5. The area under the receiving operating characteristic curves was 0.76 in full-tears.
