As an extremely common symptom and major source of lost productivity, mechanical sciatica places a heavy burden on public health.
Methods:
We retrospectively reviewed 1092 medical records to determine the epidemiological, clinical, imaging study, and therapeutic characteristics of mechanical sciatica. We also looked for factors associated with adverse outcomes.
Results:
Mean patient age was 45.0 +/- 13.3 years, and 61.8% of patients were women. A history of low back pain was noted in 35.2% of cases. A single nerve root was involved in 68% of cases, and L5 was the most commonly affected root. Disk herniation was the cause in 58.4% of patients. First-line conservative treatment provided relief in 75% of cases, and the overall 6-month outcome was favorable in 76.5% of cases.
Conclusion:
The multivariate analysis conducted in the overall patient population showed that factors associated with adverse 6-month outcomes were heavy labor (odds ratio (OR) = 1.69; 95% confidence interval (95% CI) = 1.01-2.86; P = 0.049) and obesity (OR = 1.5; 95% CI = 1.01-2.47; P = 0.05).
