STUDY DESIGN: Retrospective study of consecutive 113 cervical kinetic magnetic resonance images (kMRIs) and 57 radiographs. OBJECTIVE: To elucidate the relationship between C2-6 or C2-7 Cobb angle and cervical sagittal alignment parameters using kMRI, and evaluate the visibility of C6 and C7 inferior endplates on cervical radiographs. SUMMARY OF BACKGROUND DATA: Several studies have used C2-6 Cobb angle instead of C2-7 Cobb angle since C7 inferior endplate is not always visible due to overlying shadows...

STUDY DESIGN: Retrospective case-control study. OBJECTIVE: To report culturing patterns and results in the setting of presumed aseptic revision spinal surgery. SUMMARY OF BACKGROUND DATA: The indications for obtaining cultures in revision spinal surgery remain unclear in the absence of a definitive diagnosis of infection. Culture results and risk factors for having positive cultures in this setting have not been previously studied. METHODS: We retrospectively reviewed 595 consecutive revision spine surgeries performed by four senior spine surgeons between 2008 and 2013...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To demonstrate the relationship between perioperative use of catheters and the incidence of surgical site infection (SSI) after cervical spine surgery, after adjusting for patient's age, severity of comorbidity, surgical approach, and use of instrumentation. SUMMARY OF BACKGROUND DATA: Although the association between SSI and the use of arterial catheters (ACs) or central venous catheters (CVCs) is established in cardiac surgery, the relation in the cervical spine was not well elucidated...

STUDY DESIGN: Prospective, randomized double-blinded placebo-controlled clinical trial. OBJECTIVE: To evaluate if 90-day subcutaneous injections with 20 μg teriparatide increases the volume and quality of the fusion mass compared to placebo based on 12 month postop fine cut CT-scans. The secondary objective is to evaluate if PTH increases fusion rates compared to placebo. SUMMARY OF BACKGROUND DATA: Few studies have investigated the effects of PTH on fusion in patients undergoing spinal arthrodesis...

STUDY DESIGN: Prospective multicenter study of the changes in SRS-22 scores for 78 patients younger than 25 years old surgically treated for lumbosacral spondylolisthesis OBJECTIVE.: Report the change of health-related quality of life (HRQOL) in patients younger than 25 years after surgical treatment of lumbosacral spondylolisthesis. SUMMARY OF BACKGROUND DATA: There is a paucity of data with regard to the influence of surgical treatment on the HRQOL of patients with lumbosacral spondylolisthesis...

OBJECTIVE: The objective of this study was to evaluate, in a synthetic bone model, the difference in primary and revision pull-out strength using pedicle screws of different thread designs. SUMMARY OF BACKGROUND DATA: Over the past few decades, there has been a growing interest in optimising the screw pull-out strength using various screw designs (single-thread, mixed-thread, dual-thread)...

STUDY DESIGN: Prospective case series. OBJECTIVE: To assess a new protocol for full spine X-ray using copper (Cu) filters to reduce radiation exposure in patients with adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Radiation exposure is associated with an increased risk of cancer development in children. To reduce the radiation exposure without compromising the image quality using existing radiographic equipment, a new computed radiography protocol was optimized using a variety of heavy metal filters...

STUDY DESIGN: Retrospective analysis of prospectively collected data. OBJECTIVE: To determine the ability of Revised Cardiac Risk Index (RCRI) to predict adverse cardiac events following posterior lumbar decompression (PLD). SUMMARY OF BACKGROUND DATA: PLD is an increasingly common procedure used to treat a variety of degenerative spinal conditions. The RCRI is used to predict risk for cardiac events following non-cardiac surgery. There is a paucity of literature that directly addresses the relationship between RCRI and outcomes following PLD, specifically, the discriminative ability of the RCRI to predict adverse post-operative cardiac events...
