Đánh giá kết quả điều trị rách bán phần gân cơ trên gai bằng liệu pháp tiêm collagen typ I tại chỗ dưới hướng dẫn của siêu âm tại Bệnh viện E

Abstract

Shoulder pathology is increasingly prevalent and significantly impacts quality of life. Currently, local collagen injection therapy is utilized in the management of partial supraspinatus tendon tears. This study aims to evaluate the outcomes of treating partial supraspinatus tendon tears using ultrasound-guided Type I Collagen injections. This prospective, interventional study was conducted on 52 patients (53 shoulders) diagnosed with partial supraspinatus tendon tears at the Department of Rheumatology, E Hospital, from August 2024 to June 2025. Patients received ultrasound-guided injections of Type I Collagen (2ml /week) for 5 consecutive weeks, with a follow-up assessment at 12 weeks. The results showed a reduction in the VAS score by 75.64% and the SPADI score by 78.47%, while the shoulder abduction angle increased by 27.09% (p < 0.001). Ultrasound evaluation indicated a 49.5% reduction in tear area and a 29.5% reduction in thickness. Mild local pain was reported in 11.3% of patients, with no serious complication observed. Ultrasound-guided Type I Collagen injection therapy is effective in reducing pain, improving range of motion, and supporting tendon structural regeneration, with a favorable safety profile.
