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.

Case Reports
Putative risk of substantial venous air embolism during vertebroplasty: a technical observation.
Technical report. ⋯ VAE is a complication with associated morbidity and mortality from percutaneous procedures for the treatment of compression fractures. An understanding of the causes, prevention, identification, and management when it occurs will serve to improve patient care and reduce morbidity.

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.

Variation in abundance and structure of chondroadherin (CHAD) were studied in the extracellular matrix (ECM) of scoliotic and normal human discs. ⋯ As CHAD can interact with both the ECM and the cells, it can provide a mechanism for regulating cell metabolism and ECM structure, and so play a role in promoting matrix homeostasis. Thus, changes in CHAD abundance or structure could be associated with the pathologic changes occurring in the scoliotic IVD.
