Comparative StudyReconstructive techniques study after anterior decompression of multilevel cervical spondylotic myelopathy.
Retrospectively compared 2 reconstructive techniques after the anterior decompression of multilevel cervical spondylotic myelopathy. ⋯ This study clearly demonstrates that, adequate decompression can be achieved for the multilevel cervical spondylotic myelopathy with both methods, and the hybrid method offers better biomechanical stability and fusion results than the corpectomy method, and obviates the need for staged circumferential procedures.

Comparative StudyMotion-preserving surgery can prevent early breakdown of adjacent segments: Comparison of posterior dynamic stabilization with spinal fusion.
A retrospective study. ⋯ Prevalence of adjacent-segment disease and reoperation rate seemed to be lower in ligamentoplasty than fusion surgeries, but the difference was not significant. Ligamentoplasty circumvented adjacent-segment disease for longer period than fusion surgeries. Although the rates of additional surgeries in PLIF and PLF were comparable, PLIF developed adjacent-level instability and required fusion surgery more frequently than PLF.

Comparative StudyComparison of the percutaneous screw placement precision of isocentric C-arm 3-dimensional fluoroscopy-navigated pedicle screw implantation and conventional fluoroscopy method with minimally invasive surgery.
Retrospective clinical study to compare the percutaneous screw placement precision of isocentric C-arm (Iso-C) 3-dimensional fluoroscopy-navigated pedicle screw implantation and conventional fluoroscopy. ⋯ This study demonstrates the feasibility of placing percutaneous posterior lumbar pedicle screws with the assistance of Iso-C 3-dimensional navigation.

Comparative StudyA comparative MRI study of upper and lower lumbar motion segments in patients with low back pain.
The study is a prospective cross-sectional study of 514 patients with low back pain and sciatica. ⋯ The study revealed that pathological alteration in vertebral end plates is the same in upper and lower lumbar bony tissues as detected by Modic's criteria, whereas those of intervertebral discs is different regarding spinal level and risk factor.

Comparative StudyCadaveric evaluation of minimally invasive posterolateral thoracic corpectomy: a comparison of 3 approaches.
A cadaver study comparing 3 different minimally invasive approaches to the anterior thoracic spine. ⋯ Minimally invasive thoracic corpectomy is feasible and a 6 cm approach off of midline appears optimal.
