Even though catastrophizing can negatively moderate the outcome of surgery for lumbar spinal stenosis (LSS), it is still unclear whether pain catastrophizing is an enduring stable or a dynamic structure related to pain intensity after spine surgery. ⋯ The present study shows that pain catastrophizing can change in association with the improvement in pain intensity after spine surgery. Therefore, catastrophizing may not be an enduring stable construct, but a dynamic construct.

Laryngeal penetration-aspiration, the entry of material into the airways, is considered the most severe subtype of dysphagia and is common among patients with acute cervical spinal cord injury (SCI). ⋯ The necessity of bronchoscopies, postinjury lower cervical spine anterior surgery, coughing, throat clearing, choking, and changes in voice quality related to swallowing was a markedrisk factor for aspiration and penetration following a cervical SCI. These factors and signs should be used to suspect injury-related pharyngeal dysfunction and to initiate preventive measures to avoid complications. The clinical swallowing evaluation is a relevant adjunct in the management of these patients and can improve the detection of penetration and aspiration.

The importance of surgeon volume as a quality measure has been defined for a number of surgical specialties. Meaningful procedural volume benchmarks have not been established, however, particularly with respect to lumbar spine surgery. ⋯ The results of this work allow us to identify meaningful volume-based benchmarks for the performance of common lumbar spine surgical procedures including decompression, discectomy, and fusion-based procedures. Based on our determinations, readily achievable goals for individual surgeons would approximate an average of four discectomy and lumbar interbody fusion procedures per month, three posterolateral lumbar fusions per month, and at least one decompression surgery every other week.

Anterior cervical discectomy and fusion (ACDF) and cervical disc replacement (CDR) are both acceptable surgical options for the treatment of cervical myelopathy and radiculopathy. To date, there are limited economic analyses assessing the relative cost-effectiveness of two-level ACDF versus CDR. ⋯ Two-level CDR and ACDF are both cost-effective strategies at 5 years. Neither strategy was found to be more cost-effective with an ICER greater than the $50,000/QALY WTP threshold. The assumptions used in the analysis were strongly validated with the results of the PSA.
