Overview
Brief Summary
In this prospective study the investigators seek to evaluate clinical outcomes after repairing the defect of intervertebral disc with autologous BMSC/gelatin sponge during microendoscopic discectomy for participants of lumbar disc herniation.
Detailed Description
The participants with lumbar disc herniation diseases are treated by Microendoscopic discectomy, and they are divided into four groups depend on whether the defect is repaired with Autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge or not and whether the defect is sutured or not. In the first group,the defect of intervertebral disc is repaired with Autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge and sutured. In the second group, the defect of intervertebral disc is repaired with autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge but not sutured after discectomy. In the third group, the defect of intervertebral disc is sutured but not repaired with autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge after discectomy. In the four group, the defect of intervertebral disc is neither sutured nor repaired with autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge after discectomy.

Outcomes
Primary Outcomes
Changes from baseline in Oswestry Disability Index(ODI)
Time Frame: Baseline, post-op 3 months, 6 months,12 months
The self-completed questionnaire contains ten topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel.Each topic category is followed by 6 statements describing different potential scenarios in the patient's life relating to the topic. The patient then checks the statement which most closely resembles their situation. Each question is scored on a scale of 0-5 with the first statement being zero and indicating the least amount of disability and the last statement is scored 5 indicating most severe disability. The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100). Zero is equated with no disability and 100 is the maximum disability possible.
Secondary Outcomes
- Changes from baseline in Visual Analogue Scale(VAS)(Baseline, post-op 3 months, 6 months,12 months)
- Changes from baseline in The Short Form (36) Health Survey(SF-36)(Baseline, post-op 3 months, 6 months,12 months)
- Change from Baseline in The Size of Disc Protrusion(Baseline, post-op 12 months)
- Change from Baseline in Magnetic Resonance Classification of Lumbar Intervertebral Disc Degeneration（Pfirrmann classification）(Baseline, post-op 12 months)
- Change from Baseline in The Height of Disc on MRI Scans(Baseline, post-op 12 months)
