Comparative StudySurgical strategy for multilevel severe ossification of posterior longitudinal ligament in the cervical spine.
A retrospective clinical study was conducted. ⋯ Anterior corpectomy and fusion was significantly more effective for multilevel severe OPLL when compared with posterior laminoplasty in the cervical spine. If having technical difficulties and posterior decompression was alternatively performed, instrumented fusion was recommended to help to restore cervical lordosis and produce better results according to this study.

Comparative StudyComparison between MRI and myelography in lumbar spinal canal stenosis for the decision of levels of decompression surgery.
A retrospective case-control study. ⋯ The number of levels of decompression surgery for LSCS as decided by MRI would be less than that by myelography with CTM. Myelography with CTM is more reliable and reproducible than MRI for preoperative evaluation of LSCS.

Incidence of early complications in cervical spine surgery and relation to preoperative diagnosis: a single-center prospective study.
Prospective observational cohort study. ⋯ Complications in cervical spine procedures occurred most frequently in cases involving trauma and spinal oncologic procedures. This study illustrates that the incidence of early complications in cervical spine procedures is greater than appreciated earlier. This difference likely arises owing to the use of a broad definition of perioperative complications, elimination of recall bias through use of a prospective assessment, and overall case complexity. Accurate assessment of the incidence of early complications in cervical spine surgery is important for patient counseling and in design of prospective quality improvement programs.

Comparative StudyA comparison of CT-based navigation techniques for minimally invasive lumbar pedicle screw placement.
A comparison of 2 surgical techniques. ⋯ The use of an intraoperative 3-dimensional fluoroscopy system with an image-guidance system results in greater accuracy of pedicle screw placement than the use of preoperative CT scans, although potentially dangerous placement of pedicle screws can be prevented by the use of EMG monitoring of lumbar nerve roots.

The safe placement of upper and middle thoracic pedicle screws in pediatric deformity.
A retrospective clinical study to discuss the diameter of pedicle screw used in upper and middle thoracic vertebrae of pediatric patients with spinal deformity. ⋯ It is safe and feasible to use internal pedicle screw fixation to treat pediatric patients with upper and middle thoracic deformity in the process of screw placement, a pedicle screw with a larger diameter can be accommodated in upper and middle thoracic pedicles, if the axis of pedicle screw is confirmed within the pedicle walls. The most appropriate diameter of the screws can be determined concurrently by the palpation of the surgeon when placing the screw and referring to the pedicle screw diameter measured by CT before operation.
