Comparative Study
Biomechanical comparison of anterior, posterior, and circumferential fixation after one-level anterior cervical corpectomy in the human cadaveric spine.
In vitro biomechanical study of cadaveric cervical spine. ⋯ After C5 corpectomy, with intact PLs and facet capsules, anterior instrumentation is sufficient for spinal stabilization as the resultant construct is more rigid than the intact state. In the presence of C5 corpectomy with PL and bilateral facet capsule disruption, anterior plus posterior instrumentation is more rigid than anterior instrumentation alone in the axial and coronal planes and more rigid than posterior instrumentation without anterior cage in the sagittal plane.

Comparative Study
Rates of infection after spine surgery based on 108,419 procedures: a report from the Scoliosis Research Society Morbidity and Mortality Committee.
Retrospective review of a prospectively collected database. ⋯ Our data suggest that postsurgical infection, even among skilled spine surgeons, is an inherent potential complication. These data provide general benchmarks of infection rates as a basis for ongoing efforts to improve safety of care.

Retrospective, case series. ⋯ Nonambulatory status and a preoperative curve magnitude (≥ 60°) are directly associated with an increased risk for major complications and indirectly associated with increased length of stay. As such, we recommend operative intervention in neuromuscular scoliosis before curve progression to ≥ 60°. Level of Evidence. Level III.

Meta Analysis Comparative Study
High-dose ketorolac affects adult spinal fusion: a meta-analysis of the effect of perioperative nonsteroidal anti-inflammatory drugs on spinal fusion.
Meta-analysis of literature. ⋯ Although randomized controlled trials would be optimal for meta-analyses, the data of this review revealed that short-time (<14 days) exposure to normal-dose NSAIDs (ketorolac, diclofenac sodium, celecoxib, or rofecoxib) were safe after spinal fusion, whereas short-time (<14 days) exposure to high-dose ketorolac increased the risk of nonunion, which meant that the effect of perioperative NSAIDs on spinal fusion might be dose-dependent. Further studies would be needed to find out whether long-time exposure to normal-dose NSAIDs could also increase the risk of nonunion and which type of NSAIDs would like to have a worse effect on spinal fusion.

Randomized Controlled Trial Comparative Study
Unilateral versus bilateral balloon kyphoplasty for multilevel osteoporotic vertebral compression fractures: a prospective study.
A prospective study of patients who underwent multilevel balloon kyphoplasty at a single institute. ⋯ Both unilateral and bilateral kyphoplasty markedly improve symptom-related clinical effects of multilevel vertebral compression fractures and result in significant vertebral height restoration and kyphosis correction that remains stable for at least 2 years after treatment.
