RESULTS 44 (13%) patients had radiographic non-union and 301 (87%) were fused at 24 months post-op. At 24 months, PROs were similar between the two groups. Seven patients in the Nonunion group (16%) and 10 (3%) in the Fused group had additional surgery at the index level prior to the 24 -follow-up (p = 0.003). Over the 84-month follow-up a total of 9 patients in the Nonunion group (21%) and 22 (7%) in the Fused group had additional surgery at the index level (p = 0.009). CONCLUSION While the radiographic non-union rate at 24 months was 13%, PROs show that many of the radiographic non-unions were asymptomatic. Although the majority of patients with radiographic non-union did not undergo additional surgery, the rate of secondary surgeries at the index level was significantly higher in the radiographic non-union group. LEVEL OF EVIDENCE 2.STUDY DESIGN Retrospective case series OBJECTIVE. To study the feasibility, outcomes and complications of Transpedicular vertebrectomy (TPV) and reconstruction for metastatic lesions to the thoracic spine. SUMMARY OF BACKGROUND DATA Metastatic lesions to the thoracic spine may need surgical treatment requiring anterior-posterior decompression/ stabilization. Anterior reconstruction may be performed using PMMA cement or cages. Use of cement has been reported to be associated with complications. METHODS From 2008-16, consecutive cases (single surgeon) undergoing TPV for thoracic spine metastasis (T2 -12) were included. Demographic, surgical and clinical data was collected through chart review. MRI, CT, PET images were used to identify extent of disease, epidural spinal cord compression (ESCC), and degree of vertebral body collapse. Hall-Wellner confidence band was used for the survival curve. RESULTS 96 patients were studies with a median age 60 years. Most patients 56 (58%) presented with mechanical pain. 29% tastatic lesions. We also discuss some important steps for use of PMMA to avoid complications. LEVEL OF EVIDENCE 4.STUDY DESIGN Retrospective study using a national administrative database. OBJECTIVE To define the cohort differences in patient characteristics between patients undergoing cervical disc arthroplasty (CDA) and anterior cervical discectomy and fusion (ACDF) in a large national sample, and to describe the impact of those baseline patient characteristics on analyses of costs and complications. SUMMARY OF BACKGROUND DATA CDA was initially studied in high quality, randomized trials with strict inclusion criteria. Recently a number of non-randomized, observational studies have been published an attempt to expand CDA indications. These trials are predisposed to falsely attributing differences in outcomes to an intervention due to selection bias. METHODS Adults undergoing ACDF or CDA between 2004 and 2014 were identified using ICD-9-CM diagnosis and procedure codes. Perioperative demographics, comorbidities, complications, and costs were queried. Patient characteristics were compared via chi-square and t-tests. Cost,antly attenuated the apparent benefit for CDR on costs and medical complications. LEVEL OF EVIDENCE 3.STUDY DESIGN This is a prospective, stratified randomized, multicenter, 4-year follow-up study. OBJECTIVE The authors aimed to evaluate the long-term clinical efficacy and safety of CaO-SiO2-P2O5-B2O3 glass ceramics (BGS-7) spacers in 1-level posterior lumbar interbody fusion (PLIF) at a 4-year follow-up. SUMMARY OF BACKGROUND DATA According to 1-year follow-up results, BGS-7 spacer showed similar fusion rates and clinical outcomes compared with titanium cage. A long-term follow-up study beyond 2 years is necessary to investigate the status of intervertebral bone graft volumes. Selleck FHD-609 Moreover, longer follow-up is mandatory to also evaluate the safety and efficacy of BGS-7 spacers, because they remain in the intervertebral space for a long time. MATERIALS AND METHODS In this prospective, randomized, multicenter, 4-year follow-up study, we evaluated 62 of the 74 patients who underwent 1-level PLIF. During 1-level PLIF, titanium cages filled with autologous local bone were inserted into the control group patients and sion rates and clinical outcomes in both the BGS-7 spacer and autologous bone with a titanium cage in 1-level PLIF. However, the BGS-7 spacer implants showed a larger area of fusion with the endplates than that of autologous bone with a titanium cage. Therefore, the results demonstrated that the BGS-7 spacer can be considered as a novel intervertebral spacer to achieve successful spinal fusion without safety concerns for long-term use.OBJECTIVES The current study assessed the role of hypervigilance for bodily sensations in the back in long term low back pain (LBP) problems. METHODS People with chronic low back pain (CLBP), recurrent low back pain (RLBP), and no LBP were compared on the extent to which they attended to somatosensory stimuli on the back during a movement task. To measure hypervigilance, somatosensory event-related potentials (SEP) to task-irrelevant tactile stimuli on the back were measured when preparing movements in either a threatening or a neutral condition, indicated by a cue signaling possible pain on the back during movement or not. RESULTS Results showed stronger attending to stimuli on the back in the threat condition than in the neutral condition, as reflected by increased amplitude of the N96 SEP. However, this effect did not differ between groups. Similarly, for all three groups the amplitude of the P172 was larger for the threatening condition, suggesting a more general state of arousal resulting in increased somatosensory responsiveness. No significant associations were found between somatosensory attending to the back and theorized antecedents such as pain catastrophizing, pain-related fear and pain vigilance. DISCUSSION The current study confirmed that individuals preparing a movement attended more towards somatosensory stimuli at the lower back when anticipating back pain during the movement, as measured by the N96 SEP. However, no differences were found between participants suffering from CLBP or RLBP, or the healthy controls.BACKGROUND Before an intervention can be implemented to improve pain-related self-efficacy, assessment is required. The aim of the present study was to provide a systematic review on which self-efficacy scales are being used among patients with back pain and to evaluate their psychometric properties. METHODS A systematic search was executed in January 2019 and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 checklist served as a guide for conducting the study. Electronic databases included CINAHL, MEDLINE, PubMed, PsycINFO, PSYNDEX, and Sport Discus. Publications in English or German language that focused on adult patient population suffering from back pain and provided validation or reliability measures on pain-related self-efficacy were included. RESULTS A total of 3,512 records were identified resulting in 671 documents after duplicates were removed. 233 studies were screened full-text and a total of 47 studies addressing 19 different measures of pain-related self-efficacy were included in the quality analysis.
