In the anatomy of a normal spine, due to the curvatures in various regions, the C7 plumb line
(C7PL) passes through the sacrum so that the head is centered over the pelvic-ball and …

BACKGROUND CONTEXT Pedicle subtraction osteotomy (PSO) is a challenging restoration
technique for sagittal imbalance and is associated with significant complications. One of the …

Abstract Purpose Lumbar procedures for Transforaminal Lumbar Interbody Fusion (TLIF)
range from open (OS) to minimally invasive surgeries (MIS) to preserve paraspinal …

Study Design. This study combined all prior research involving human volunteers in low-
speed rear-end impacts and performed a comparative analysis of real-world crashes using …

Objective The objective of this study was to compare the biomechanical differences of
different rod configurations following anterior column realignment (ACR) and pedicle …

Purpose Non-neutral neck positions are important initial conditions in impact scenarios,
associated with a higher incidence of injury. Repositioning in finite element (FE) neck …

Background Sagittal balance is an important clinical parameter of the spine for its normal
function. Maintenance of the sagittal balance is crucial in the clinical management of spinal …

Objective To determine the effects of thoracic stiffness on mechanical stress in the lumbar
spine during motion. Methods To evaluate the effect of preoperative thoracic flexibility, stiff …

There is considerable biomechanics literature on finite element modeling and analysis of the
spine. To accurately mimic the biomechanical behavior of the vertebral column, a generated …

Methods: A validated osseo-ligamentous model from C2-C7 was used in this study. The C2-
C7 Cobb angle of the base model was modified to represent: lordotic (− 10), straight (0), and …
