简要总结

The purpose of this study is to determine the effectiveness of minimally invasive decompression and fusion over the traditional open decompression and fusion in patients with single-level lumbar stenosis caused by degenerative spondylolisthesis. Postoperative follow-up will continue for 12 months. Сlinical, safety, radiological and cost-effectiveness endpoints will be evaluated.

研究组 & 干预措施

Open TLIF

Patients will undergo a single level decompression and fusion using an open traditional technique. Followed posterior screw fixation is mandatory.

干预措施: lumbar fusion

Minimally invasive TLIF

Patients will undergo a single level decompression and fusion using a minimally invasive technique. Followed posterior screw fixation is mandatory.

干预措施: lumbar fusion
