Objective : Percutaneous lumbar approaches such as arthroscopic discectomy, laser discectomy, and nucleotome remain controversial and have technical limitations to free fragment disc, bony pathology and access to L5-S1, The purpose of this study was to determine efficacy of this new endoscopic system and to report techniques and tactics. Methods : From July 1997 to May 1998, we treated 40 consecutive patients(43 levels) with the MED system. Mean age was 32 years(range ; 18 to 62). There were 30 males and 10 females. All patients had sciatica with SLRT limitation. There were 23 patients with disc herniation at L4-5 and 14 patients at L5-S1. Three patients had 2 level disc herniations. There was one far lateral disc herniation at L4-5. Results : Using modified MacNab criteria, there were 37 excellent results and 3 good result. Most patients were discharged within 3-4 days except 2 patients with dural tearing. There were no other complications. Mean operation time was 1.5 hours(range : 40 minutes to 2.5 hours). Conclusion : The MED system is a reliable approach to lumbar disc herniations. This system combines the advantages of conventional open surgery and a minimally invasive technique. As tactics for the doctors who wish to attempt, "palpate" the lamina by first dilator, identification of interlaminar space by removal of overlying soft tissue and confirmation of the shoulder portion of nerve root before discectomy are important to this procedure. We conclude that lumbar disc herniations can be successfully treated with MED approach.
