RESUMEN
OBJECTIVE: To evaluate the accuracy of ultrasound guided hip trochanteric bursa (subgluteus maximus bursa) injection by using pelvis computed tomography (CT) scan with contrast dye. METHOD: Nine patients (37~79 years old) with greater trochanteric pain syndrome (GTPS) were recruited for the study. In lateral decubitus position with pain side up, ultrasound guided injection was done into trochanteric bursa located between gluteus maximus and medius tendons with a mixture of 10 ml 0.5% lidocaine and 10 ml contrast dye (Omnipaque) in all study subjects. Accuracy of injection was assessed by pelvis CT scan within 1 hour after bursa injection. RESULTS: As results of pelvis CT scan, all subjects' contrast dyes were accurately injected within trochanteric bursa space from trochanter to proximal gluteus. CONCLUSION: We confirmed that ultrasound guided trochanteric bursa injection was accurate and easy to perform.
