Abstract

Background: This study aims at evaluating normal anatomy of rotator interval and its structures both on ultrasonography and MRI. Secondly to standardise the ultrasonography technique. To validate the efficacy of grey scale ultrasonography in evaluating the normal rotator interval anatomy, its pathologies and to correlate with MRI findings. The following pathologies have been observed coracohumeral ligament tears, long head of biceps tendon tears and dislocation, biceps pulley injuries and Periarthritis of shoulder joint. Materials and Methods: A Prospective observational Study was done among 30 Patients who were clinically diagnosed / suspicious for rotator interval pathologies in Department of Radio diagnosis, Kamineni Hospitals. L.B. Nagar, Hyderabad for a period of 12 months. Patients with Malignant lesions, Trauma, Massive Rotator Cuff injuries were excluded from the study. Informed consent was obtained from the patients or from the nearest kin of the patients included in this study. A complete history of patient’s present/past illness was taken, and detailed clinical examination was performed in all the cases and findings were recorded in the pre structured questionnaire. Initially MRI was done and the examiner is blind folded to MRI findings, then patients taken for USG examination. Data was entered into Microsoft excel data sheet and was analyzed using SPSS 22 version software. Categorical data was represented in the form of Frequencies and proportions. Chi-square test or Fischer Exact test was used as test of significance for qualitative data. Validity of USG was estimated by Sensitivity, Specificity, PPV, and NPV. p value of <0.05 was considered as statistically significant.
