Abstract
Study Design
This is a review of the literature about radiographic positioning for patients with sagittal imbalance.
Objectives
We wanted to verify the optimal radiographic positioning for patients with sagittal imbalance.
Summary of Literature Review
The standing lateral whole spine radiograph for identifying the sagittal alignment has a different value for the SVA according to the radiographic positioning.
Results
The fists-on-the clavicle position or the cross-arm position not only represents a functional standing position, but it also causes a less negative shift of the SVA in patients with sagittal imbalance. Both the extended hip and knee positions are necessary to exclude a compensation mechanism of the lower extremity.
