The study is a prospective outcome study to evaluate the effectiveness and treatment outcomes of microendoscopic decompressive laminotomy (MEDL) with objective evaluation tools. The patients who fulfill the selection criteria will be enrolled to collect the pre-operative clinical data including demographic data, image studies, and functional evaluation for neurological symptoms and disability.

The patient will receive MEDL and post-operative follow-up will be arranged at 1 week, 1 month, 6 months, and 12 months after the operation. All the collected data will be analyzed to evaluate the efficacy and treatment results of MEDL.
