BACKGROUND: Pseudoarthrosis after pedicle subtraction osteotomy (PSO) can require
revision surgery due to posterior rod failure, and the stiffness of these revision constructs has …

Introduction Studies document rod fracture in pedicle subtraction osteotomy (PSO) settings
where disk spaces were preserved above or adjacent to the PSO. This study compares the …

Object Ankylosing spondylitis (AS) is a genetic condition that frequently results in spinal
sagittal plane deformity of thoracolumbar or cervicothoracic junctions. Generally, a …

Study Design. Biomechanical laboratory research. Objective. To characterize the structural
stiffness of opening and closing wedge osteotomies and the independent effect of rod …

Object Primary spine tumors frequently involve the C-2 vertebra. Complete resection of the
lesion may require total removal of the C-2 vertebral body, pedicles, and dens process …

Sagittal imbalance of the cervicothoracic spine often causes severe pain and loss of
horizontal gaze. Traditionally, C7 opening wedge osteotomy has been classically performed …

Ankylosing spondylitis is a genetic condition [1] that frequently results in spinal sagittal plane
deformity of thoracolumbar or cervicothoracic junction. Generally, a combination of …

Failure of the posterior rods in long thoracolumbar deformity correction cases often requires
revision surgery to treat the pseudoarthrosis and prevent loss of correction. While the entire …
