Abstract:

Objective To compare the effect of multislice spiral CT examination (CT examination) and color Doppler ultrasound (ultrasound examination) in the diagnosis of bone and joint tuberculosis. Methods Twenty-three cases of bone and joint tuberculosis from January 2015 to December 2019 were retrospectively analyzed. These cases were diagnosed by surgical pathology (9 cases), bacteriological diagnosis (10 cases) and clinical diagnosis (4 cases). Among them, there were 12 cases of simple bone tuberculosis, 9 cases of simple synovial tuberculosis, and 2 cases of total joint tuberculosis. CT examination and ultrasound examination were performed in all patients, and the diagnostic value of the two examination techniques for various types of bone and joint tuberculosis was analyzed. Results Accuracy of CT diagnosis of bone and joint tuberculosis was 65.2% (15/23) and ultrasound was 56.5% (13/23). There was no significant statistical difference between them (χ²=0.365, P=0.546). Accuracy of CT diagnosis of simple bone tuberculosis (83.3%, 10/12) was significantly higher than ultrasound (33.3%, 4/12), and there was significant statistical difference between them (χ²=6.171, P=0.013). In 9 cases of synovial tuberculosis, ultrasound correctly diagnosed 8 cases, CT correctly diagnosed 3 cases. In 2 cases of total joint tuberculosis, CT correctly diagnosed 2 cases, ultrasound correctly diagnosed 1 case. Conclusion For simple bone tuberculosis, CT examination is better than ultrasound. For simple synovial tuberculosis, ultrasound examination is better than CT examination.
