Perhaps the single greatest error that a surgeon hopes to avoid is operating at the wrong site. In this report, the authors describe the incidence and possible determinants of incorrect-site surgery (ICSS) among neurosurgeons. ⋯ Neurosurgical ICSSs do occur, but are rare events. Although there are significant limitations to the survey-based methodology, the data suggest that the prevention of such errors will require neurosurgeons to recognize risk factors and increase the use of intraoperative imaging.

Increased signal intensity of the spinal cord on magnetic resonance (MR) imaging was classified pre- and postoperatively in patients with cervical compressive myelopathy. It was investigated whether postoperative classification and alterations of increased signal intensity could reflect the postoperative severity of symptoms and surgical outcomes. ⋯ The postoperative increased signal intensity classification reflected postoperative symptomatology and surgical outcomes to some extent, without statistically significant differences. The alteration of increased signal intensity was seen postoperatively in 24 patients (23%) and was not correlated with surgical outcome.

The goal in this study was to demonstrate the safety and efficacy of anterior cervical discectomy and fusion ([ACDF]; single- or multilevel procedure) performed using titanium plates and polyetheretherketone (PEEK) spacers filled with recombinant human bone morphogenetic protein-2 (rhBMP-2) impregnated in a type I collagen sponge to achieve fusion. ⋯ An ACDF performed using a PEEK spacer filled with rhBMP-2 leads to good to excellent clinical outcomes and solid fusion, even in multilevel cases and in patients who are smokers. The incidence of symptomatic dysphagia may be decreased with a lower dose of rhBMP-2 that is placed only within the PEEK spacer.
