STUDY DESIGN: Retrospective review. OBJECTIVE: To compare the safety and accuracy of the freehand technique versus stereotactic navigation for placement of iliac screws. SUMMARY OF BACKGROUND DATA: Iliac screw fixation is often used to augment lumbosacral reconstruction in advanced spine disease to increase the likelihood of successful arthrodesis. Iliac screws can be placed with image guidance, using either intraoperative fluoroscopy or computed tomography (CT) to guide navigation...

STUDY DESIGN: Cadaveric radiostereometric analysis study. OBJECTIVE: To quantify the ability of 5 commonly used immobilizers to restrict cervical spine movement, including intervertebral movement, in three directions. SUMMARY OF BACKGROUND DATA: Evidence about the ability of many clinically used cervical immobilizers to restrict cervical movement is limited. Furthermore, their effect on intervertebral movement is unknown. METHODS: Radiographic inert beads were implanted in the cervical vertebral bodies of five fresh-frozen human cadavers...

STUDY DESIGN: . Retrospective cohort study OBJECTIVE.: To evaluate hospital outcomes in dialysis dependent patients undergoing elective lumbar surgeries. SUMMARY OF BACKGROUND DATA: Due to their overall poor health status and concomitant comorbidity burden, spinal surgery in dialysis dependent patients represents a significant challenge to spine surgeons. Large studies evaluating their immediate post-operative outcomes in elective lumbar surgery are lacking. METHODS: Utilizing the National Inpatient Sample (NIS), an estimated 1,834 dialysis-dependent patients undergoing elective lumbar spine surgery for degenerative lumbar conditions were compared to an estimated 2,522,594 non-dialysis dependent patients undergoing the same procedures between 2002 and 2012...

STUDY DESIGN: Biomechanical study using a three-dimensional nonlinear finite element (FE) model. OBJECTIVE: To analyze biomechanical changes with three prostheses based on two-level arthroplasty and to verify the biomechanical efficiency of dynamic cervical implants (DCIs) with a stand-alone U-shaped structure. SUMMARY OF BACKGROUND DATA: Few studies have compared biomechanical behavior of various prostheses as they relate to clinical results after two-level total disc replacement (TDR)...

STUDY DESIGN: A genetic association study of GPR126 gene with adolescent idiopathic scoliosis (AIS) in the Chinese population. OBJECTIVE: To investigate whether rs9403380, rs6570507 and rs7774095 of GPR126 gene are susceptible locus of AIS and to further determine the functional variants regulating gene expression in tissues of AIS. SUMMARY OF BACKGROUND DATA: Previous studies have identified several new susceptibility locus for AIS in GPR126 gene...

STUDY DESIGN: The synchrotron radiation based micro-CT (SRμCT) and micro-CT (μCT) were applied to comparatively assess the intervertebral disc (IVD) and endplate (EP). OBJECTIVE: To explore a new approach to evaluate the detailed structure of the IVD and EP during maturation and aging in a murine model. SUMMARY OF BACKGROUND DATA: To date, methods to observe the morphological changes in the IVD and EP from rodent have been relatively limited...

STUDY DESIGN: Retrospective study on prospectively collected data. OBJECTIVE: To study the impact of nutritional status, as measured by serum albumin level, on patient outcomes following posterior cervical fusion (PCF) surgery. SUMMARY OF BACKGROUND DATA: Malnutrition is a potential modifiable risk factor that has garnered an increasing amount attention within orthopedics in recent years. There is evidence to suggest the role of nutritional status in lumbar and ACDF surgery, yet the data for PCF is still lacking...

STUDY DESIGN: Cross sectional survey OBJECTIVE.: To investigated the association between self-reported low back symptoms and symptoms in the hip, knee, and ankle in a high-risk occupational group SUMMARY OF BACKGROUND DATA.: Low back pain, with or without lower extremity referral, poses a major challenge to occupational productivity, especially in farming. Although low back symptoms can occur independent of lower extremity symptoms, anatomical positioning of nerves supplying the lower limbs means structural and physiological changes in the spine can lead to referred pain in the lower limbs, but the magnitude of the association between low back and lower extremity symptoms is unclear...

OBJECTIVE: To explore the prevalence and functional importance of LBX1 polymorphisms in AIS patients within the Northern Chinese Han population. SUMMARY OF BACKGROUND DATA: AIS is the most common subtype of idiopathic scoliosis. Genetic factors such as LBX1 polymorphisms have been recently proved to be associated with AIS in some populations...
