analysis of the prevalence of lumbar annular tears in adult patients using magnetic resonance imaging data

This study aimed to evaluate the lumbar annular tears prevalence regarding the patient’s history factors, and magnetic resonance imaging (mri) recorded data.materials and methods: in this study, 218 patients (106 men and 112 women) were evaluated; 136 cases (63 men and 73 women, 20-80 years, mean: 45.4±14.8 years) with lower back pain (lbp) and high-intensity zone (hiz) were diagnosed based on mr images. the diagnosed annular tears from the mri data, body mass index (bmi, kg/m2), and physical activity of the patients were recorded, and the prevalence of lumbar annular tears was evaluated regarding the mentioned parameters.results: the prevalence of annular tears was 31.6% at l5/s1 (43/136 patients), 43.4% at l4/l5 (59/136 patients), 16.9% at l3/l4 (23/136 patients), 4.4% at l2/l3 (6/136 patients), and 3.7% at l1/l2 spinal disc space (5/136 patients). most patients with annular tears had lbp (>60%). based on the patient's history, 25% of patients had bmi above 30, 8.8% had post-traumatic history, 15.4% had a history of falling down, 19.1% had slipped down history, 16.2% were athletes, and 15.4% performed heavy work.conclusion: the prevalence of lumbar annular tears was higher in patients having lbp and a bmi over 30, which should be considered possible risk factors. this study demonstrated that annular tears are more likely to occur in lower lumbar discs, especially in l4/l5 and l5/s1 discs.
