Influence of prone, supine, and lateral positions during spine surgery on vascular, abdominal, and postural anatomy: a comprehensive review and Bayesian meta-analysis.

ABSTRACT:

Background

Patient positioning alters the three-dimensional relationship between the spine and surrounding neurovascular and visceral structures, thereby influencing both the technical feasibility and safety of lumbar procedures. Quantitative estimates of these positional shifts remain heterogeneous.

Objective

To determine, across contemporary imaging studies, how prone, supine, and lateral decubitus positions alter the displacement of great vessels and retroperitoneal organs, the location of the psoas/lumbar plexus, and segmental lumbar lordosis.

Methods

MEDLINE, Embase, and CENTRAL were searched from 2015 to 2025. Eligible studies compared at least two positions in adults and reported millimetre or degree differences for the outcomes of interest. Random‑effects (REM
