Full-endoscopic Foraminotomy in Degenerative Spondylolisthesis: A “Module-based” Approach for Surgical Planning and Execution

Purpose Degenerative Lumbar Spondylolisthesis (DSL) is a common spinal pathology characterized by the anterior slippage of one vertebral body on another. DSL caused mainly degeneration intervertebral disc in first place, with subsequent facet joints that end causing slippage. As disease evolves, stability restored as result advanced and collapse. But while this natural evolution takes may produce radicular symptoms different mechanisms. To present “module-based” approach for surgical planning execution full-endoscopic foraminotomy DSL, combined case examples most scenarios. Methods We propose “module-based surgery” using standard endoscopic technique baseline. According to patient’s clinical imaging characteristics, several “modules” can be added. The resulting surgery summation basic plus all additional required modules. ResultsSurgical modules description are provided. ConclusionTransforaminal lumbar represents minimally invasive treat foraminal foraminal-lateral recess stenosis. its multiple scenarios represent challenge surgeon. Module-based help systematize execute these demanding procedures.
