Role of MRI in Evaluation of Patients with Rotator Cuffinjuries and Labral Tears with Arthroscopic Correlation

Introduction MRI can depict the endurance between rotator cuff degeneration or tendinopathy& full or partial thickness rotator cuff injuries. So careful observation to the bursal, intrasubstance, and articular surface morphology of the tendon is required. Aim& Objective The aim of the study is to analyse and describe spectrum of MRI findings in a suspected cases of labral and rotator cuff injuries with arthroscopic correlation. Materials and methods An analytical study conducted in the department of radio diagnosis MIMS, Nellimarla, Vizainagaram between January 2017 to march 2018. Our study included a total of 34 patients who have been referred for shoulder MRI following injury to shoulder. We used Philips Ingenia 1.5 Tesla MR Imaging unit. Patients underwent arthroscopy in case of failure of nonsurgical techniques, and the affected shoulder joint was inspected and MRI findings were correlated. Followed by calculation of specificity, sensitivity, negative predictive and positive predictive values. Results Rotator cuff injuries affected the supraspinatus muscle in 46 % followed by the infraspinatus 37 %, subscapularis in 16 % and 1 % injuries has been reported to teres minor in our study. Most rotator cuff injuries were strains (48 %), followed by partial thickness tears (29 %) full thickness tears (22 %) and labral tears in (1 %) subjects. Conclusion Supraspinatus muscle is the most involved muscle with sprains& PTT being the most frequently encountered injuries in rotator cuff. Thus MRI has an ultimate precision for the characterization of rotator cuff injuries, with relatively high sensitivity and specificity rates.
