Sciatica refers to pain affecting the back, hip, and outer side of the leg, caused by compression of a spinal nerve root in the lower back often owing to degeneration of an intervertebral disc. The objective of this study was to determine the frequency of sciatica in patients with lower back pain using magnetic resonance imaging (MRI). Data was collected by filling the predesign questionnaire. Information for filling the questionnaire was taken by reports of MRI scan for backache. Patients were presented with multiple symptoms out of which 4 (5.6%) patients presented with history of trauma. 37 (59.7%) patients represented with the history pain radiating to one or both legs. 27 (43.50%) patients showed disc bulge. 40 (64.50%) patients showed stenosis in nerve root (L4-S1) and 40 (64.50%) patients were diagnosed with sciatica. Careful assessment of risk factors in patients with lower back pain using MRI could help in prevention of several spinal diseases. Being an important diagnostic tool in diagnosis of sciatica MRI may provide significant prognostic information of the disease.
