Spontaneous Correction of Sagittal Imbalance After Isolated Lumbar Decompression

Multicenter Study of Spontaneous Correction of Sagittal Imbalance After Isolated Decompression Surgery Without Corrective Fusion Procedure for Lumbar Spinal Stenosis

Enrollment

165 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

LUMBAR STENOSIS Sagittal Imbalance Degeneration Lumbar Spine Lumbar Decompression

Summary

Sagittal spinal imbalance may be caused by orthopedic problems, compression of the neural structures of the spinal canal, and pain syndrome (functional imbalance). Sagittal imbalance in combination with appropriate clinical symptoms may require surgical correction of the spine with fixation. However, in some cases, patients experience spontaneous correction of sagittal balance after isolated decompression without any correction or fusion. Therefore, it is necessary to clarify whether isolated decompression may cause spontaneous correction of sagittal imbalance in patients with degenerative lumbar stenosis.

Eligibility

Interventions

PROCEDUREIsolated lumbar decomression

All patients will undergo microsurgical decompression of stenosed neural structures of the lumbar canal at all clinically significant levels with saving the posterior spinal column (type of decompression may be as unilateral, bilateral, or bilateral from a unilateral approach (over-the-top)), including endoscopic decompression. Degenerative lumbar stenosis may be caused by thickened yellow and posterior longitudinal ligaments, facet joints hypertrophy, vertebral body osteophytes posteriorly, synovial (facet joints cysts) and disc cysts.
