No results posted yet for this study

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.

Conditions

  • Lumbar Spine Degeneration
  • Lumbar Spinal Stenosis

Interventions

PROCEDURE

Lateral lumbar interbody fusion

LLIF is an indirect decompression technique, and does not directly remove the disc or osteophyte protruding into the spinal canal. Its decompression effect is not as thorough as traditional posterior decompression surgery. Usually, posterior decompression is required for patients who have unsuccessful indirect decompression.
