Ultrasound of the Shoulder Joint for Impingement Syndrome, Correlation With Arthroscopic Surgery for Operability of Partial Supraspinatus Tendon Tear

Abstract

To show the accuracy of ultrasound studies in diagnosing impingement syndrome of the shoulder joint by correlating with arthroscopic surgery for operability of partial supraspinatus tendon tear. AIM: To correlate the sensitivity and specificity of ultrasound in the diagnosis for intrinsic causes of impingement syndrome of the shoulder joint, correlation with arthroscopic surgery and operability for supraspinatus tear. MATERIALS AND METHODS: This was a prospective study done on 40 patients clinically diagnosed with impingement syndrome who underwent ultrasound assessment. Arthroscopic correlation was done in 38 patients. OBSERVATIONS AND RESULTS: In our study of rotator cuff integrity assessment, ultrasound showed type-1 in 3(7.5%), type-2 in 10(25%), type-3 in 21(52.5%), type-4 in 3(7.5%) and type-5 in 3(7.5%) When compared to the arthroscopic surgery findings, Sensitivity and specificity of PTT was 85.5% and 75% respectively. On dynamic evaluation of shoulder joint for impingement, our present study showed grade-2 abnormality in 30 patients (75%) and 8(20%) patients had grade-1 abnormality, this was found to be statistically significant. DISCUSSION: ultrasonography can detect impingement syndrome and partial tear of the SST with high specificity and sensitivity, which makes it the most cost effective, noninvasive, rapidly performed, and widely available and most acceptable investigation to the patients.
