Abstract

This study was conducted to evaluate the safety and result of ultrasound-guided synovial biopsy in the diagnosis of hip joint diseases. The study was conducted on 27 patients with hip synovial abnormalities on ultrasound (US) and magnetic resonance imaging (MRI), who underwent biopsy at Hanoi Medical University Hospital from July 2020 to February 2025. The obtained specimens were analyzed for histopathology, bacterial culture, and tuberculosis PCR testing to accurately determine the cause of the lesions. The results showed that the group of patients over 50 years old was dominant (70.4%), with an average age of 56.44 ± 15.26. The success rate in sampling was 92.6%. Complications occurred in 14.8% of patients, including mild bleeding at the needle puncture site, with no serious complications. Histopathologically, 74.1% of patients were diagnosed with chronic inflammation, 7.4% with granulomatous inflammation specific to tuberculosis, 11.1% with septic arthritis, and 3.7% with synovial tumors. Overall, the study showed that US-guided synovial biopsy is a safe, minimally invasive, and highly accurate method in diagnosing synovial pathology of hip joint.
