ABSTRACT
I. Objective: to highlight the clinico-MRI pro?le of lumbar disc herniation on sciatic lumboradiculgia in bi- river hospital settings (cases of Kinshasa and Brazzaville). This was a II. Materials and methods: retrospective, documentary and multicenter study of 302 patients who performed lumbar MRI examinations in 18 months in hospitals in Kinshasa and Brazzaville. The mean age of patients was 53.4 years. The most represented age group III. Results: was 50 to 59 years old. The female sex was predominant (55.4%) with a ratio of 0.79. The majority of patients (68.2%) came from Kinshasa. Lumboradiculalgia was the most predominant indication with (49.3%), followed by low back pain (48%). The majorityof MRI examinations (91.4%) were performed without injection of contrast product. T1 and T2 weightings were performed in 100% of patients. Diseased disc degeneration was found at (41.7%) and lumbar disc herniation at (27.2%). The MRI examination was normal in (47%) of the patients. Based on potentially clinically positive relevance, only 48.7% of our MRI diagnoses were clinically positive. Age (p=0.000), lumboradiculalgia (p=0.000) and specialist physician prescription (0.039) had a statistically signi?cant relationship with clinically positive diagnosis. HDL is a pathological reality in the hospitals of IV. Conclusion: Kinshasa and Brazzaville. The MRI pro?le found mainly corroborates the observations of the literature. Lumbar disc herniation and degenerative disc disease remain the most frequently encountered pathologies on magnetic resonance imaging in hospitals in Kinshasa and Brazzaville. They are at the origin of the lumbar spinal syndrome and affect the young population. The posterolateral disc herniation remains the most frequently encountered subtype with predominance of damage to the ?oors: L4-L5 and L5-S1
