Fused Spinopelvic Angle in Adult Spinal Deformity with Pure Sagittal Malalignment: A Postoperative Threshold Associated with Proximal Junctional Kyphosis
Background: Determining the appropriate magnitude of lumbar lordosis (LL) correction in adult spinal deformity (ASD) remains controversial. The fused spinopelvic angle (FSPA), a posture-independent parameter, may provide a geometric measure of fused-construct orientation associated with proximal junctional kyphosis (PJ...
