Assessment of Maximum Extension Reservoir of the Lumbar Spine Using Fulcrum Hyperextension Radiographs in Severe Sagittal Spinal Malalignment
Fulcrum hyperextension radiographs best represented the MER. Therefore, it can be used to predict the maximum LL by LLIF alone, which can be estimated as fulcrum hyperextension LL+7.6°. This threshold can guide the selection between LLIF alone and ACR in deformity correction using the lateral approach.
