LLIF Plus Posterior Decompression for Severe Lumbar Spinal Stenosis

Status Completed

Clinical Trial Summary

Lateral lumbar interbody fusion (LLIF), as a minimally invasive technique, is an indirect decompression technique, and its decompression effect is not as thorough as traditional posterior decompression surgery. For certain patients with severe lumbar stenosis, additional posterior decompression is required. However, whether additional posterior decompression is necessary for these patients is unknown. Radiographic predictors of failed indirect decompression via LLIF is unknown. In current randomized, controlled trial , the investigators compare the clinical outcomes of patients with severe lumbar stenosis who received LLIF plus posterior decompression and those without posterior decompression.

Clinical Trial Description

The current randomized controlled trial consists of two groups. Patients included in the study are with Schizas's stenosis grades C. Patients in one group received transpsoas lateral lumbar interbody fusion. Patients in the other group received transpsoas lateral lumbar interbody fusion plus posterior decompression. Patients will be followed for one year. Clinical outcomes of the two groups will be compared. And radiographic predictors of failed indirect decompression via LLIF will be analyzed. ;
