STUDY DESIGN: Animal experimental study with intervention OBJECTIVE.: The purpose of this study was to elucidate whether local administration of an α-antagonist around the dorsal root ganglion (DRG) suppressed sympathetic nerve sprouting, from the acute to the chronic pain development phase, in a lumbar radiculopathy model using immunohistochemical methods. SUMMARY OF BACKGROUND DATA: The abnormal sympathetic-somatosensory interaction may underlie some forms of neuropathic pain...

STUDY DESIGN: Retrospective review of a prospective Adolescent Idiopathic Scoliosis (AIS) registry OBJECTIVE.: To study the evolution of the operative approach, outcomes and complication rates in AIS surgery over the past 20 years. METHODS: 1819 AIS patients (1995-2013) with 2-year F/U were studied. Operative approach, perioperative parameters, major complication rates, and SRS outcomes were assessed. Linear regression was used to assess the trend of changes over 5-year quartiles...

STUDY DESIGN: In Vitro Study. OBJECTIVE: To evaluate the effect that factors released from human posterior spinal bone dust have on primary human osteoblast growth and maturation. SUMMARY OF BACKGROUND DATA: Bone dust, created during spinal fusion surgeries has the potential to be used as an autologous bone graft by providing a source of viable autologous osteoblasts and mesenchymal stem cells with osteogenic potential. To date, no information is available on whether bone dust also provides a source of anabolic factors with the potential to enhance osteoblast proliferation and maturation, which would enhance its therapeutic potential...

Blake N Shultz, Alexander T Wilson, Nathaniel T Ondeck, Patawut Bovonratwet, Ryan P McLynn, Jonathan J Cui, Jonathan N Grauer
STUDY DESIGN: Retrospective matched cohort study of prospectively collected data. OBJECTIVE: To compare rates of adverse events and readmission between lumbar total disc arthroplasty (TDA) and anterior lumbar interbody fusion (ALIF) using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. SUMMARY OF BACKGROUND DATA: TDA and ALIF may be considered for similar degenerative indications. However, there have been few large-cohort comparison studies of short-term clinical outcomes for these procedures...

STUDY DESIGN: Ovine in vivo study. OBJECTIVE: To perform lateral approach lumbar surgery in an ovine model to administer an injectable riboflavin (RF) cross-linked high-density collagen (HDC) gel and to assess its ability to mitigate intervertebral disc (IVD) degeneration after induced annulus fibrosus (AF) injury. SUMMARY OF BACKGROUND DATA: Biological-based injectable gels have shown efficacy in restoring biomechanical, radiographic, and histological parameters in IVD-injured animal models...

STUDY DESIGN: A study of mechanically-induced herniation in punctured ovine discs followed by structural analysis. OBJECTIVE: To investigate whether an annular puncture influences the path that herniation takes by providing direct passage for nucleus through the annulus and therefore whether it increases the risk of acute herniation from overload at the site of damage independent of any longer-term degeneration. SUMMARY OF BACKGROUND DATA: 10 years after treatment with discography both degenerative changes and frequency of herniation have been shown to increase compared to untreated discs...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To investigate the effect depression has on the improvement of patient reported outcome measures (PROMs) following lumbar decompression. SUMMARY OF BACKGROUND DATA: Decompression without fusion is a viable treatment option for lumbar spine stenosis. Depression reportedly has a negative impact on PROMs after certain types of spine surgery, though verification of this with new, more precise outcome measures is needed...

STUDY DESIGN: A prospective imaging study OBJECTIVE.: The study investigated whether the classification of increased signal intensity (ISI) using magnetic resonance imaging (MRI) reflects the severity of symptoms in patients with cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA: Although the ISI on MRI in patients with CSM is observed, the degree of ISI has not been examined. The association between ISI and the surgical outcomes in cervical myelopathy remains controversial...

STUDY DESIGN: Meta-analysis of randomized controlled trials. OBJECTIVE: To evaluate the effectiveness of perioperative supplemental ketamine to reduce postoperative opioid analgesic consumption following spine surgery. SUMMARY OF BACKGROUND DATA: Although low-dose supplemental ketamine has been known to reduce pain after surgery, there is conflicting evidence regarding whether ketamine can be effective to reduce opioid consumption following spine surgery...

STUDY DESIGN: A retrospective study. OBJECTIVE: To evaluate radiographic and cosmetic outcomes following posterior-only cervicothoracic hemivertebra resection and instrumentation. SUMMARY OF BACKGROUND DATA: Cervicothoracic hemivertebra is a rare congenital deformity. It locates between the mobile cervical spine and the fixed thoracic spine, leading to rapid curve progression, shoulder imbalance, fixed torticollis and facial asymmetry. METHODS: This study reviewed a consecutive series of 18 patients with cervicothoracic hemivertebra...

STUDY DESIGN: Meta-analysis of published randomized controlled trials (RCTs). OBJECTIVE: To determine whether anterior cervical discectomy and fusion (ACDF), cervical disc replacement (CDR) or minimally invasive posterior cervical foraminotomy (MI-PCF) provides the best outcomes for patients with symptomatic single-level, single-side, cervical radiculopathy.

Pradeep Suri, James Rainville, Evelien de Schepper, Julia Martha, Carol Hartigan, David J Hunter
STUDY DESIGN: Prospective, longitudinal case-crossover study. OBJECTIVE: To determine whether physical activities trigger flare-ups of pain during the course of acute low back pain (LBP). SUMMARY OF BACKGROUND DATA: There exist no evidence-based estimates for the transient risk of pain flare-ups associated with specific physical activities, during acute LBP. METHODS: Participants with LBP of duration < 3months completed frequent, Internet-based serial assessmentsat both 3- and 7-day intervals for 6 weeks...

STUDY DESIGN: cohort comparison study. OBJECTIVE: To compare perioperative outcomes between navigated and conventional single-level instrumented posterior lumbar fusions in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database.

STUDY DESIGN: Biomechanical analysis using a validated nonlinear finite element (FE) model. OBJECTIVE: To combine the strategy of two-level hybrid surgery (HS) to explore how prostheses affect cervical biomechanics. SUMMARY OF BACKGROUND DATA: Few FE studies have explored differences in biomechanical behavior between combined and stand-alone structured prostheses with HS. No FE studies have considered whether the prosthesis type and hybrid strategy influence two-level HS...
