Clinical Trial Summary

This study will be conducted at Research Institute of Traumatology and Orthopedics (NRITO) n.a. Ya.L.Tsivyan, Novosibirsk, Russia. The current study is prospective observational study to evaluate the efficacy of preoperative estimation of disc herniation recurrence among patients with lumbar disc herniation using predictive mathematical model at terms 3 years postoperatively . It is expected to enroll 350 patients aged 18-70 with lumbar disc herniation. Risk estimation of disc herniation recurrence will be evaluated preoperatively, then patient will undergo conventional microdiscectomy. Postoperative eximanation will include Visits every 6-months during 3 years to evaluate clinical outcomes.

Intervention

Diagnostic Test:
• Preoperative risk estimation of disc herniation recurrence
Risk estimation of disc herniation recurrence will be evaluated preoperatively, depend on the risk significance each patient will be assigned to one of two groups - with high risk and low risk. Then each patient will undergo conventional one-level microdiscectomy.
