STUDY DESIGN: Retrospective analysis of prospective registry OBJECTIVE.: To investigate associations of preoperative narcotic use with outcomes after adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA: We hypothesized that preoperative narcotic use would predict longer hospital stays, greater postoperative narcotic use, and greater disability 2 years after ASD surgery. METHODS: A multicenter database of surgical ASD patients was analyzed retrospectively for patients with self-reported data on preoperative narcotic use...

STUDY DESIGN: We retrospectively analyzed factors associated with spinopelvic mechanical failure after total sacrectomy. OBJECTIVE: To find the rate and type of mechanical fixation failure after total sacrectomy and to identify the associated risk factors. SUMMARY OF BACKGROUND DATA: Although rigid fixation has been achieved, mechanical failure is sometimes encountered in reconstruction after total sacrectomy. The incidence and factors associated with spinopelvic fixation mechanical failure after total sacrectomy are still not clear...

STUDY DESIGN: Retrospective cohort study OBJECTIVE.: To determine the rate of venous thromboembolism event (VTE) and risk factors for their occurrence in patients with vertebral fractures. SUMMARY OF BACKGROUND DATA: Deep vein thrombosis or pulmonary embolism (VTE) events are a significant source of potentially preventable morbidity and mortality in trauma patients. In patients with traumatic vertebral fractures, a common high-energy injury sometimes resulting in spinal cord injury, there is debate about what factors may be associated with such VTEs...

STUDY DESIGN: This is a retrospective cohort study. OBJECTIVE: To evaluate the long-term outcomes of selective one- to two-level anterior lumbar interbody fusions (ALIFs) in the lower lumbar spine versus continued nonsurgical management. SUMMARY OF BACKGROUND DATA: Low back pain associated with lumbar intervertebral disc degeneration is common with substantial economic impact, yet treatment remains controversial. Surgical fusion has previously provided mixed results with limited durable improvement of pain and function...

STUDY DESIGN: Multicenter, prospective study of consecutive adult spinal deformity (ASD) patients. OBJECTIVE: To evaluate back and leg pain as a combined score in ASD and compare their relative and cumulative correlations with HRQOL and sagittal parameters. SUMMARY OF BACKGROUND DATA: Pain and disability are commonly reported in patients with ASD. This can affect their back, their legs or both. ASD-associated pain has been correlated with numerous health-related quality of life (HRQOL) scores and radiological parameters...

STUDY DESIGN: The efficacy of estrogen on vessel angiogenesis in acute spinal cord injury in a rat model were evaluated by synchrotron radiation. OBJECTIVE: Here, we investigate the change in injured spinal cord vessels and used the synchrotron radiation to investigate the effect of estrogen on vessel angiogenesis and functional recovery in a rat model of SCI. SUMMARY OF BACKGROUND DATE: The promotion of angiogenesis after spinal cord injury (SCI) may be a therapeutic target in the treatment of SCI...

STUDY DESIGN: Mixed-method. OBJECTIVE: To evaluate the association between objective and subjective cervical range of motion (ROM) among patients with neck pain, and to assess the awareness of impairments. SUMMARY OF BACKGROUND DATA: Cervical ROM is frequently used to evaluate neck pain, but it is also important to know what a patient expects from treatment, because this can profoundly affect treatment outcomes and patient satisfaction. METHODS: We used a cervical ROM instrument, the Neck Disability Index (NDI), and a self-administered ROM questionnaire for the neck (S-ROM-Neck)...

STUDY DESIGN: Prospective, non-randomized study. OBJECTIVE: To assess surgical outcomes of multilevel facetectomy and rod curvature with simultaneous double-rod rotation technique for anatomical spinal reconstruction in thoracic adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Although some surgical techniques maintain or restore thoracic kyphosis (TK), next-generation strategies for thoracic AIS should include corrections in three anatomical planes...

STUDY DESIGN: Cross-Sectional Study. OBJECTIVE: The goal of this study is to investigate how surgeons differ in collar and narcotic use, as well as return to driving recommendations following cervical spine surgeries and the associated medico-legal ramifications of these conditions. SUMMARY OF BACKGROUND DATA: Restoration of quality of life is one of the main goals of cervical spine surgery. Patients frequently inquire when they may safely resume driving after cervical spine surgery...

STUDY DESIGN: The comparison of sacroiliac joint (SIJ) angular motions, pelvis ligaments strain, load sharing, and stress distribution across the joint for male and female spine-pelvis-femur models using finite element analysis. OBJECTIVE: To quantify biomechanical parameters at SIJ for all motions for both male and female models. SUMMARY OF BACKGROUND DATA: SIJ has been recognized as a main source of pain in 13% to 30% of patients with low back pain...

STUDY DESIGN: A cross-sectional comparative study. OBJECTIVE: This study aimed to investigate the flexion-relaxation phenomenon (FRP), in standing trunk flexion and slumped sitting tasks, by comparing children and adolescents suffering from nonspecific chronic low back pain (NSCLBP) with controls (CTRL). SUMMARY OF BACKGROUND DATA: The absence of the FRP can accurately discriminate adults with NSCLBP from those without during standing trunk flexion and slumped sitting tasks...

STUDY DESIGN: A retrospective study. OBJECTIVE: The aim of this study was to determine the publication rate and impact factors (IFs) among all abstracts presented at the 2010 and 2012 meetings of the International Society for the Study of Lumbar Spine (ISSLS). SUMMARY OF BACKGROUND DATA: The publication rate of abstracts presented at overseas meetings was reported to be around 50%. However, the publication rate and IFs of oral and poster presentations made at ISSLS meetings were unclear...

STUDY DESIGN: Randomized controlled trial OBJECTIVE.: Compare early physical therapy versus usual care in patients with low back pain. SUMMARY OF BACKGROUND DATA: Early physical therapy (PT) has been associated with reduced downstream healthcare utilization in retrospective studies, but not investigated prospectively in the military health system. METHODS: Military service members seeking care from a general practitioner were recruited. Patients attended a 20-minute self-management class with focus on psychosocial resilience and then randomized to usual care only (UC) versus immediately starting a 3-week physical therapy program (PT)...

STUDY DESIGN: Retrospective longitudinal cohort study. OBJECTIVE: To investigate the association between diffuse idiopathic skeletal hyperostosis (DISH) and reoperation in patients treated surgically for lumbar spinal stenosis (LSS) in long-term results. SUMMARY OF BACKGROUND DATA: Few studies have evaluated DISH as a potential risk factor of poor surgical results for LSS. METHODS: This study included 1063 responders to a postoperative postal survey out of 2363 consecutive patients who underwent surgery for LSS between 2002 and 2010...
