Lumbar plexus passes through psoas posteriorly to SCPL on both side at L1-2, L2-3 level and on the concave side at L3-4 level. And they shift anteriorly to SCPL on the convex side at L3-4 level and on both sides at L4-5 level. It indicates a ventral migration of lumbar plexus from L1-2 to L4-5 level. Preoperative magnetic resonance neural imaging is valuable for assessing the safety of XLIF approach. Operation from the concave may reduce the risk of injury to lumbar plexus.
