Sagittal Thoracic and Lumbar Spine Profiles in Upright Standing and Lying Prone Positions Among Healthy Subjects: Influence of Various Biometric Features.

Study Design: A prospective study was performed on the assessment of both thoracic and lumbar spine sagittal profiles (from C7 to S1).

Objective: To propose a new noninvasive method for measuring the spine curvatures in standing and lying prone positions and to analyze their relationship with various biometric characteristics.

Summary Of Background Data: Modifications of spine curvatures (i.
