The purpose of this study is to evaluate the clinical and radiological results of surgical treatment of one-level central stenosis of the lumbar spine using traditional open approach (PLIF) and a minimally invasive procedure (MIS TLIF). According to the hypothesis, we assume that unilateral approach of MIS TLIF allows for adequate bilateral decompression of one-level central stenosis of the lumbar spine. Using MIS TLIF it is possible to perform reliable fixation of a spine segment and the formation of a complete intervertebral bone fusion. The long-term clinical results of surgical treatment with minimally invasive technologies (MIS TLIF) and traditional open approach (PLIF) suspected to be comparable.
