NCT01622413

Brief Summary

This study compares an endoscopic transforaminal surgical technique for the treatment of a herniated disc to the standard microsurgical procedure. Clinical parameters as well as health economy will be assessed. The study hypothesis is that the endoscopic approach is equivalent or superior to microdiscectomy.
