To investigate the impact of lumbar fusion on spinopelvic sagittal alignment from standing to sitting position and the influencing factors of postoperative functional limitations due to lumbar stiffness. ⋯ After lumbar fusion, changes of lumbopelvic sagittal parameters from standing to sitting would be restricted. Adjacent segment lordosis could partially compensate for this restriction. For patients with lumbosacral fusion, postoperative functional limitations due to lumbar stiffness were related to age and the postoperative ∆PT from standing to sitting.

To determine the effect of endplate reduction on the final healing morphology and degenerative changes in intervertebral discs. ⋯ The reduction rate in the central area is significantly lower than that in the peripheral area. Although all of the intervertebral discs corresponding to fractured endplates had degenerated to different degrees, successful endplate fracture reduction can obviously delay the degeneration of intervertebral discs.

Observational Study
Characteristics and comparative study of thoracolumbar spine injury and dislocation fracture due to tertiary trauma.
Thoracolumbar spine injury is frequently seen with high-energy trauma but dislocation fractures are relatively rare in spinal trauma, which is often neurologically severe and requires urgent treatment. Therefore, it is essential to understand other concomitant injuries when treating dislocation fractures. The purpose of this study is to determine the differences in clinical features between thoracolumbar spine injury without dislocation and thoracolumbar dislocation fracture. ⋯ III.

To evaluate the associations among the validated lumbar vertebral bone quality (VBQ) score, and cervical and thoracic VBQ scores. ⋯ Thoracic VBQ provides values representative of the validated lumbar VBQ score. Cervical VBQ scores are distinct from lumbar VBQ scores and do not provide adequate surrogate values of lumbar VBQ.

A unilateral vertical sacral fracture that exits medial or through the L5-S1 facet joint is considered to affect the lumbo-sacral integrity, and it is denoted as an indication for surgical fixation. However, no studies have analysed the outcomes after non-operative treatment of such injuries. ⋯ Our study indicates that 47% of Isler's fractures were mechanically stable and could be effectively treated non-operatively with good radiological and functional outcomes.
