Study Design: Review of the literature. Objectives: Anterior column realignment (ACR) is a
powerful but relatively new minimally invasive technique for deformity correction. The purpose …

OBJECTIVE Lateral lumbar interbody fusion (LLIF) is a useful minimally invasive technique
for achieving anterior interbody fusion and preserving or restoring lumbar lordosis. However, …

Background Context Rod fracture at the lumbosacral (LS) junction remains challenging in
long segment fusions and likely stems from increased LS strain. Reduction of LS …

OBJECTIVE S2-alar-iliac (S2AI) screw fixation effectively ensures stability and enhances
fusion in long-segment constructs. Nevertheless, pelvic fixation is associated with a high rate of …

OBJECTIVE S2 alar-iliac (S2AI) screw fixation effectively enhances stability in long-segment
constructs. Although S2AI fixation provides a single transarticular sacroiliac joint fixation (…

Objective The high mechanical stress zone at the sudden transition from a rigid to flexible
region is involved in proximal junctional kyphosis (PJK) physiopathology. We evaluated the …

Study Design. This is a cross-sectional survey. Objective. The aim was to assess the reliability
of a proposed novel classification system for thoracic disc herniations (TDHs). Summary of …

Objective The lordotic shape of the lumbar spine differs substantially between individuals.
Measuring and recording strain during spinal biomechanical tests is an effective method to …

BACKGROUND CONTEXT Anterior column realignment (ACR) is a powerful but destabilizing
minimally invasive technique for sagittal deformity correction. Optimal biomechanical …

Background: This study sought to compare index and adjacent-level biomechanics of
cadaveric specimens with mature fusion versus normal spines in intact and acutely fused …
