Retrospective clinical data analysis. ⋯ Percutaneous insertion of cannulated pedicle screws in the thoracic and lumbar spine is an acceptable technique with a low complication rate in experienced hands. The overall rate of perforation is below the higher rates reported in the literature for the open technique. Complication rates including pedicle fracture were low.

Randomized Controlled Trial Multicenter Study
Grafton and local bone have comparable outcomes to iliac crest bone in instrumented single-level lumbar fusions.
Prospective multicenter randomized clinical trail. ⋯ At 2-year follow-up, subjects who were randomized to Grafton Matrix and local bone achieved an 86% overall fusion rate and improvements in clinical outcomes that were comparable with those in the ICBG group.

This study is a research synthesis of the published literature evaluating the performance of magnetic resonance imaging (MRI) for differentiation of malignant from benign vertebral compression fractures (VCFs). ⋯ Several specific MRI features using signal intensity characteristics, morphological characteristics, quantitative techniques, and findings at other levels can be useful for distinguishing benign from malignant VCFs and can serve as inputs for a prediction model. Observer performance reliability has not been adequately assessed.

Morphometric and volumetric analyses and virtual screw placement. ⋯ Subaxial cervical unilateral translaminar screw placement is a potentially safe and effective technique to use in conjunction with preoperative CT scanning for all vertebral levels. The same is true for bilateral placement at C7 but not at C3-C6. A prospective study to evaluate the long-term outcomes of translaminar fixation at all vertebral levels is currently underway.

A retrospective observational study. ⋯ The results in this study indicated that traumatic CSF leak was not observed on CTM in patients with WAD, in whom CSF leak was suspected on RIC.
