According to researchers’ findings, preoperative MRI was able to accurately detect the 11% prevalence of tendinous insertion of the pectoralis minor.
The researchers recruited 99 patients to undergo arthroscopic exploration of pectoralis minor insertion. Two blinded observers reviewed preoperative MRIs for tendinous insertion of pectoralis minor twice within a 2-week interval, the results from which were correlated with arthroscopy as gold standard. The researchers then evaluated the effect of the variation on supraspinatus tendon tear and repair effect during arthroscopy.
Using the weighted Cohen к coefficient, the researchers determined intraobserver reproducibility and interobserver reliability.
