A retrospective analysis of prospectively collected data of 102 consecutive adult patients who underwent intraoperative neurophysiological monitoring (IOM) during spinal deformity corrective surgery. ⋯ Multimodality IOM of spinal cord sensory and motor function during surgical correction of adult spinal deformity is feasible and provides useful neurophysiological data with an overall sensitivity of 100% and a specificity of 84.3% (67% and 98%, respectively in patients undergoing major deformity correction).
-
Morphometric and volumetric analysis. ⋯ The degree of cervical angulation represents a consistent and significant anatomic relationship in the lower cervical spine and may necessitate a modified surgical approach.
-
Retrospective single center analysis. ⋯ Our analysis suggest that patients undergoing minimally invasive transforaminal lumbar interbody fusions procedures have a higher incidence of developing new radicular symptoms that could be attributed to BMP.
-
A biomechanical study with human cadaveric osteopenic lumbar vertebrae evaluating a novel method for cement augmentation of pedicle screw fixation. ⋯ This novel cement-delivery screw and injection technique provides a significant increase in resistance to pedicle screw motion, allowing placement of a standard screw that can be removed in revision surgery.

Biomechanical study of bovine spines. ⋯ This study has shown that using the FlexiCore system at 1 and/or 2 intervertebral disc spaces caudal to a scoliosis fusion model did not significantly change the sensor deflection at the 2 segments adjacent to a scoliosis fusion construct. Future research will continue to define the clinical setting and patients best suited for management by TDR systems.
