TL;DR: An ideal means of determining the MCID for a given intervention is yet to be determined and it is possible to develop a useful method provided that the assumptions and methodology are initially declared.

TL;DR: Vertebroplasty had a significantly greater improvement in pain scores but also had statistically greater risk of cement leakage and new fracture, while kyphoplasty provided significant improvement in VAS pain scores.

TL;DR: Results suggest that, in patients in whom bone regeneration may be compromised, the degradation observed with some resorbable bone grafts may contribute to the decoupling of bone regeneration and resorbtion within the graft site, which may ultimately lead to incomplete bone repair.

TL;DR: Caution should be exercised with rh-BMP-2 use in ACDF surgery as the correct dose and technique for application is not yet determined and Respiratory distress and dysphagia may result secondary to rh- BMP- 2 induced anterior neck swelling.

TL;DR: Overall the incidence of dysphagia 2 years after anterior cervical spine surgery was 13.6%, which was found to be significantly higher in women (18.3%) than men (9.9%)2 years after the surgery.

TL;DR: An algorithm for operative treatment corresponding to a newly proposed classification system of degenerative lumbar scoliosis with associated canal stenosis is presented to provide pain relief and improved functional lifestyle with minimum intervention.

TL;DR: This study suggests that fusion success with INFUSE is equivalent to ICBG for posterolateral spine fusion, and presents compelling evidence that commercially available INFuse is an effective ICBG substitute for one- and two-level postersolateral instrumented spine fusion.

TL;DR: Vertebral osteolysis can occur with the use of rh-BMP-2 in posterior lumbar interbody fusions, and Violation of the end plate during decortication may be a contributing factor.

TL;DR: This is the first study to quantitatively analyze the long-term PE damage mechanisms in contemporary TDRs, and the evidence of increasing wear with implantation time, along with the demonstrated potential for osteolysis in the spine, is warranted.

TL;DR: The high fusion rate, low subsidence, stability provided by the cage, and facilitation of radiological assessment are the result of the physical properties of the PEEK material as well as the design of the cage.

TL;DR: This study confirms the efficacy of an innovative lumbar fusion technique: an interbody femoral ring allograft, combined with an osteoinductive stimulant (rhBMP-2), protected by pedicle screws, which results in successful fusion formation in 100% of the cases in this study.

TL;DR: C1LM-C2P fixation is equivalent to C1LM -C2L fixation in flexion/extension and AP translation and superior in lateral bending and axial rotation.

TL;DR: Performing ACDF with instrumentation on an outpatient basis is feasible, and it is not associated with higher overall or hardware-related complication rates as compared with complication rates reported in the literature, suggesting that this procedure is safe to perform on a outpatient basis.

TL;DR: In this article, the authors evaluated lumbar decompression and fusion in patients over 65 years of age at a minimum 2 years post-operatively and found that patients undergoing decompression had consistently better outcomes than patients undergoing a revision procedure.

TL;DR: In a setting of normal-appearing plain radiographs, PLC injury as displayed on T1-weighted MRI and diastasis of the facet joints on CT scan seem to be the most popular determinants of probable PLC Injury among members of the Spine Trauma Study Group.

TL;DR: The potential presence of an intradural disc herniation must always be considered preoperatively on a patient whose magnetic resonance imaging study demonstrates the "hawk-beak sign" on axial imaging as well as abrupt loss of continuity of the posterior longitudinal ligament (PLL).

TL;DR: Simultaneous epidural and vascular injection is twice as likely to occur as vascular injection alone, and live fluoroscopy is recommended during contrast injection for confirmation of lumbosacral transforaminal epidural injections.

TL;DR: ACDF appears to be a safe surgical procedure with a low incidence of iatrogenic neurological injury and an intraoperative neurological deficit is possible despite normal intraoperative SSEP signals.

TL;DR: The present study found manual examination of the cervical spine to lack validity for the diagnosis of cervical zygapophyseal joint pain, and refutes the conclusion of the one previous study.

TL;DR: The strength and magnitude of their negative effects was surprising and the numerous issues exerting profound effects on the outcome of a relatively simple operation suggest that specific attention be directed at them when evaluating more complex surgical procedures.

TL;DR: The results indicate that the duration and amplitude of a spinal manipulation elicit a pattern of discharge from paraspinal muscle spindles different from slower mechanical inputs.

TL;DR: Nonoperatively treated burst fractures of the thoracic or lumbar spine in adults with or without minor neurological deficits have a predominantly favorable long-term outcome, and there seems to be no increased risk for subsequent disc height reduction in the adjacent discs.

TL;DR: FLMED offers a safe and efficacious approach to ELDHs at the lumbosacral junction by combining satisfactory visualization for adequate resection of the sacral ala with the benefits of reduced tissue injury and faster recovery times that accompany minimally invasive techniques.

TL;DR: The results encourage us to use nucleoplasty in carefully selected patients with leg pain caused by radicular encroachment and recommend applying this minimally invasive technique only in those patients with small (<6 mm) contained disc herniations, with a disc height of>or=50% and with annular integrity.

TL;DR: A modified tubular retraction system to be used with three-dimensional visualization and anterior/posterior fluoroscopic imaging, thus allowing easy visualization even in large patients and avoiding inadvertent entry into the cervical spinal canal with possible catastrophic result.

TL;DR: Comparison of the present results with previously reported data indicated that high-speed elongation may cause cervical ligaments to fail at a higher peak force and smaller peak elongation and they may be stiffer and absorb less energy, as compared with a slow elongation rate.

TL;DR: Fine-cut CT scans with reconstructions have a considerably greater degree of interobserver and intraobserver agreement compared with flexion/extension and anteroposterior radiographs.

TL;DR: This issue of The Spine Journal presents another attempt to resolve disputed claims between different camps purporting high diagnostic certainty in axial pain, and results show that manual testing and injection testing results are frequently at odds.
