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.

Device: Autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge
Participants with lumbar disc herniation diseases are treated by Microendoscopic discectomy, and the defect of intervertebral disc is repaired with Autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge after discectomy.
Procedure: The defect is sutured
Participants with lumbar disc herniation diseases are treated by Microendoscopic discectomy, and the defect is sutured after discectomy.

Procedure: The defect is sutured
Participants with lumbar disc herniation diseases are treated by Microendoscopic discectomy, and the defect is sutured after discectomy.

| No Intervention: The defect is neither sutured nor repaired 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 four group, the defect of intervertebral disc is neither sutured nor repaired with autologous Bone Marrow Stem Cell (BMSC)/gelatin sponge after discectomy. |
Outcome Measures
Primary Outcome Measures
- Changes from baseline in Oswestry Disability Index(ODI) [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 Outcome Measures
- Changes from baseline in Visual Analogue Scale(VAS) [Baseline, post-op 3 months, 6 months,12 months]
Self reported pain using a 10-point visual analogue scale (0=no pain;10=pain as bad as can be)
- Changes from baseline in The Short Form (36) Health Survey(SF-36) [Baseline, post-op 3 months, 6 months,12 months]
The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.
- Change from Baseline in Magnetic Resonance Classification of Lumbar Intervertebral Disc Degeneration（Pfirrmann classification） [Baseline, post-op 12 months]
The Pfirrmann grading system assesses degenerated intervertebral discs by MRI for the asymmetry in disc structure, distinction of the nucleus and the annulus, signal intensity of intervertebral discs and height of intervertebral discs and assigns grade I to V for disc degeneration。
- Change from Baseline in The Height of Disc on MRI Scans [Baseline, post-op 12 months]
Using imaging software, physicians will measure disc height at the treatment discs on the midline T1 sagittal view
- Change from Baseline in The Size of Disc Protrusion [Baseline, post-op 12 months]
We will measure the anteroposterior (AP) size of the disc protrusions that required treatment
Other Outcome Measures
- The Medical Records [1 months after hospital discharge]
The Medical Records including operative time、blood loss and hospital stay
