Single-center retrospective study. ⋯ Obese and morbidly obese patients have multiple comorbidities, and the spinal surgeon should be prepared to encounter perioperative complexities. Operative times are longer in comparison with normal weight patients with a higher incidence of postoperative complications. No weight loss occurs after spinal surgery.

Retrospective cohort study supplemented by analysis of postmortem spinal cord tissue. ⋯ Hyponatremia is common in the early stage post-SCI. Our results also suggest that hyponatremia is associated with the integrity of descending renal sympathetic circuits which mediate the renin-angiotensin response to neural injury, in the setting of neurogenic hypotension with cardiovascular dysfunction.

This in vitro human cadaveric study tested the loss of thoracic motion segment flexion stiffness after sequential posterior upper instrumented vertebra anchor placement techniques and posterior column destabilization. ⋯ Posterior thoracic skeletal structures involved in upper instrumented vertebra exposure andanchor placement were found to contribute to adjacent segment flexion stiffness. Although stiffness loss was small after individual procedures, the effects were additive for routinely used combinations.

Retrospective. ⋯ Intraoperative CSF leak was encountered in 6.3% of patients undergoing CC for OPLL. A successful repair was achieved using fascial graft, gelatin sponge, lumbar CSF drainage, and bed rest.

An in vitro biomechanical study of halo-vest and odontoid screw fixation of Type II dens fracture. ⋯ The present reduction in C1/2 motion observed, due to the halo-vest and dens screw combined is similar to previously reported immobilization provided by the polyaxial screw/rod system and transarticular screw fixation combined with wiring. The present biomechanical data may be useful to clinicians when choosing an appropriate treatment for those with Type II dens fracture.
