5. Comparison between MD and MED in VAS, MacNab and complications: Meta-analysis

6. 80% Life-time prevalence of back pain

7. Herniated intervertebral disc Most common in lumbar lesion

8. Lumbar Discectomy No response to conservative Tx. for 6wks Early, progressive neurologic symptom Microsugical discectomy (MD) Microendoscopic discectomy (MED)

9. MD vs MED MD Standard Short op. time Wide indication (?) MED Fast tissue recovery Short hospital stay Less Postop. pain

10. Meta-analysis
