Meta Analysis Comparative Study
A meta-analysis of circumferential fusion versus instrumented posterolateral fusion in the lumbar spine.
A meta-analysis of circumferential fusion versus instrumented posterolateral fusion (PLF) in the lumbar spine. ⋯ Compared with instrumented PLF, circumferential fusion can increase the fusion rate and reduce the reoperation rate, but it can also increase the complication rate and the amount of blood loss. No significant difference was found in the global assessment of clinical outcome about the 2 fusion procedures.

Review Case Reports
Sagittal plane considerations and the pelvis in the adult patient.
Research update, focused review. ⋯ It has become evident that good clinical outcome in the treatment of spinal deformity requires proper alignment. Pelvis parameters play an essential role not only in terms of spine morphotypes but also in regulating standing balance and postoperative alignment. Thus, optimal treatment of a patient with spinal deformity requires integration of the pelvis in the preoperative evaluation and treatment plan.

This is a multivariate analysis of a prospectively collected database. ⋯ Using multivariate analysis of a large prospectively collected data from the National Surgical Quality Improvement Program database, we identified the most important risk factors for increased postoperative spinal wound infection. We have demonstrated the high mortality, morbidity, and hospitalization costs associated with postoperative spinal wound infections. The information provided should help alert clinicians to presence of these risks factors and the likelihood of higher postoperative infections and morbidity in spinal surgery patients.

Bench-top and retrospective analysis to assess vertebral rotation based on the appearance of bilateral pedicle screws in patients with adolescent idiopathic scoliosis (AIS). ⋯ An accurate assessment of vertebral rotation can be performed radiographically, using screw lengths and screw tip-to-rod distances of bilateral segmental pedicle screws and a trigonometric calculation. These data support the use of a simple radiographic grading system to approximate apical vertebral rotation in AIS patients treated with bilateral apical pedicle screws.
