Anatomical study of the innervation of different parts of the posterior ligamentous region of the sacroiliac joint.

Background And Objectives: The periarticular sacroiliac joint (SIJ) technique has become an important area of focus, and the quartering of the SIJ posterior ligamentous region has been proposed as a way to refine this technique. However, detailed nerve distribution combined with the division of the SIJ posterior ligamentous region is lacking. We aimed to explore the innervation of the SIJ posteriorly based on the quartering of the SIJ posterior ligamentous region.

The lumbar autonomic nerves in males: a few anatomical insights into anterior lumbar interbody fusion.

Background Context: Lumbar autonomic nerve injury is an underappreciated complication of anterior lumbar spinal surgery. A detailed description of lumbar autonomic nerve anatomy would be helpful for surgeons to minimize the risk of this complication.

Purpose: This study was designed to investigate the anatomical characteristics of lumbar autonomic nerves and provide a better understanding of these nerves for anterior lumbar spinal surgery.

The Anatomical Study and Clinical Significance of the Sinuvertebral Nerves at the Lumbar Levels.

Study Design: A dissection-based study of 10 embalmed human cadavers.

Objective: The purpose of this study was to describe the sinuvertebral nerves at the lumbar level and to discuss their possible clinical significance.

Summary Of Background Data: Discogenic low-back pain is mediated by the sinuvertebral nerves.
