Synopsis

Surgical interventions may be performed to treat Lumbar Spinal Stenosis (LSS) once conservative treatment options are exhausted. However, decompression surgery with or without fusion may result in loss of physiologic lumbar lordosis which may further lead to sagittal imbalance of the spine. Radiographs collected from patients, who participated in a previously completed randomized controlled trial of an indirect decompression system, were assessed and Lumbar Lordosis (LL) angle (as measured from the superior end plate of L1 to the end plate of S1) was calculated. No change in global lordosis angle was noted up to 5-years post-procedure.
