Brief summary

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.

Inclusion criteria

* syndrome of mono- or polyradicular compression of the nerve roots with / without a reflex pain syndromes, caused by stenosis of one lumbar spine segment; * intermittent claudication caused by stenosis of one lumbar spine segment; * one-level spine stenosis in combination with local segment instability or degenerative spondylolisthesis at the same spine segment, requiring fusion in only one lumbar segment

Exclusion criteria

* bilateral foraminal lumbar spine stenosis; * lumbar spine stenosis more than one-level; * spondylolisthesis II degree and more; * sagittal imbalance; * fusion the same lumbar spine segment after surgery previously; * other diseases of the spine, including trauma, tumor and inflammatory diseases of the lumbar spine, etc.

Design outcomes

Primary

MeasureTime frameDescription
Oswestry Disability Index (ODI)Day of hospital discharge (10-15 day after surgery)Oswestry Disability Index - patient-reported physical and household activity. Minimum - 0 (the worst result, patient is not physically active). Maximum - 50 (the best result). Improvement of ODI post-operatively as compared to baseline

Secondary

MeasureTime frameDescription
VAS (back, leg)Day of hospital discharge (10-15 day after surgery), 3, 6 and 12 monthsVisual Analogue Scale (VAS) - patient-reported pain intensity (0 - no pain, 10 - unbearable pain). Improvement of VAS back- and leg pain intensity as compared to baseline
Surgery durationDay of surgerySurgery duration, in minutes
Oswestry Disability Index (ODI)3, 6 and 12 monthsOswestry Disability Index - patient-reported physical and household activity. Minimum - 0 (the worst result, patient is not physically active). Maximum - 50 (the best result). Improvement of ODI as compared to baseline
