Case Reports
Use of extracorporeal membrane oxygenation support during an emergent decompression of a thoracic epidural abscess.
Case report. ⋯ The use of ECMO support in adult spinal surgery has not been previously reported in the literature. Therefore we describe the first reported use of ECMO to maintain cardiopulmonary support in a patient unable to tolerate prone positioning during spine surgery. ECMO support can be a viable option in adult patients who need emergent spinal surgery but are unable to tolerate prone positioning secondary to cardiopulmonary complications.

We measured the expression and responses of Toll-Like Receptor 4 (TLR4) activation in the intervertebral disc (IVD) in vitro and in vivo. We hypothesize that stimulation of the IVD with the TLR4 ligand lipopolysaccharide (LPS) results in upregulation of a coordinated set of proinflammatory mediators and inhibition of matrix expression, both consistent with a molecular profile of degeneration. ⋯ This study provides the first evidence that IVD cells express TLR4 and are responsive to TLR4 activation by upregulating a coordinated set of inflammatory cytokines. This study suggests that intradiscal injection of LPS offers a model for triggering inflammation of the IVD, demonstrating that inflammatory insults alone may potentially trigger degenerative changes of the IVD.

Experimental study. ⋯ The high-dose parecoxib-soaked absorbable gelatin sponge can prevent peridural fibrosis without complications. The low-dose parecoxib and cellulose membrane provided no significant benefit vis-à-vis prevention of peridural fibrosis, as adduced from the lack of any statistically significant difference between the test and control rats.

Systematic review. ⋯ Despite high fusion rates there is a growing body of evidence that the use of BMP in PLIF and TLIF constructs does not come without potential complication. There are appreciable rates of BMP-specific complications, which include heterotopic ossification within the epidural space or neuroforamina, postoperative radiculitis, and endplate osteolysis with interbody device subsidence.

Multivariate analysis of prospectively collected registry data. ⋯ After univariate and multivariate analyses, Medicaid insurance status was found to be a risk factor for postoperative complications. This corresponds to an ever-growing body of medical literature that has shown similar trends and raises the concern of underinsurance.
