Intervertebral Disc Herniation

Brief 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.

Interventions

DIAGNOSTIC_TESTPreoperative 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.

Design outcomes

Primary

MeasureTime frameDescription
Reherniation rateat 3 years follow-up term postoperativelyRate of lumbar disc reherniation, symptomatic presence of disc herniation confirmed by MRI at the previously operated level and side

Secondary

MeasureTime frameDescription
Improvement of Oswestry Disability Index (ODI)6, 12, 18, 24, 30, 36 months follow upTo observe the improvement of ODI as compared to baseline through follow-up terms Oswestry Disability Index - patient-reported physical and household activity. Minimum - 0 % (the best result, the patient has no limitations in physical activity). Maximum - 100% (the worst result, patient is not physically active at all).
Improvement of Visual analog scale (VAS) leg pain intensity6, 12, 18, 24, 30, 36 months follow upTo observe the improvement of VAS leg pain as compared to baseline through follow-up terms.
Change from baseline in EQ-5D (EuroQl - 5 dimensional)6, 12, 18, 24, 30, 36 months follow upTo observe change in EQ-5Dl as compared to baseline
HTI Item (from SF-36)6, 12, 18, 24, 30, 36 months follow upTo observe the HTI Item (from SF-36) as compared to baseline
