Abstract

Pain at the ischial tuberosity is caused by many causes, of which the two most common causes are sacral bursitis and proximal hamstring tendinopathy. Ultrasound helps in the differential diagnosis between sacral bursitis and proximal hamstring tendinopathy when clinical symptoms are not clear and need to be differentiated from other causes. Objectives: To study the clinical characteristics of lesions and ultrasound images in patients with pain and tenderness at the ischial tuberosity. Subjects of the study: 57 patients with pain at the ischial tuberosity were diagnosed with Ischial bursitis or proximal hamstring tendinopathy on ultrasound, outpatient, or inpatient at the Department of Rheumatology, Bach Mai Hospital, from June 2020 to July 2021. Methods: A cross-sectional study. Results and conclusions: The percentages of patients with age greater than or equal to 40 was 78% and with overweight and obesity  was 50%. The mean age is 48.5 years old. The main clinical symptoms in the group of ischial bursitis were a pain when sitting for a long time (95%) and increasing pain when pressing at the ischial tuberosity (87.5%), increasing pain when lying on the side of the lesion (100). %). The percentages of positivity of 3 tests of the diagnosis of proximal hamstring tendinopathy were: "Bent-knee stretch test" (88.4%), "Puranen-Ovara Test" (90.7%), and "Modified bent-knee stretch test" (95.4%). The characteristic ultrasound image of ischial Bursitis is a cyst with a capsular (86%), with internal septum (81%), containing hyperechoic fluid (62%). While the image of the proximal hamstring tendinopathy is an enlarged tendon compared to the healthy side, hyperechoic (91%), tendinitis (58%)
