Abstract

Objectives: Describing the images of facet joints on magnetic resonance imaging and ultrasound in the lumbar facet osteoarthritis patients treated at the Rheumatology Department, Thai Nguyen National Hospital. Subjects and methods: Cross-sectional description of 88 patients diagnosed lumbar facet osteoarthritis at The Department, Thai Nguyen National Hospital during the period from July 2022 to July 2023. Results: Male 37(42.0%), female 51(58.0%). The oldest is 93 years old, the youngest is 30 years old. The average age of the patients is 68± 13.02 years old, 79.5% patients are over 60 years old. The average duration of the disease is 65.2 ± 52.2 months, the most recent is 1 month, the longest is 120 months. The most common location for facet joint osteoarthritis is L4-L5 (75.0% MRI, 80% Ultrasound), facet joint L3-L4 (67.0% MRI, 31.8% Ultrasound). On MRI, grade 2 facet joint lesions account for at most 50%. Grade 1 and grade 3 injuries are 25%; Joint fluid images have the highest rate of 73.9%, bone spurs 63.3%, joint space narrowing 61.4%, bone edema 60.2%. On ultrasound, only joint fluid was detected in 52.3% and bone spurs in 47.7%. 100% of facet joint inflammatory lesions detected on MRI were detected on ultrasound at a rate of 92.0%. Conclusion: Lumbar facet joint arthritis occurs mainly in women, the frequency increases with age. The common location for facet joint inflammation is L4-L5. Level 2 injuries account for 50%. Common lesions are joint fluid, bone spurs, and joint space narrowing. MRI has higher sensitivity and specificity than ultrasound in diagnosing facet joint inflammation.
