    ABSTRACT: Our understanding of the pathophysiological processes that comprise the early secondary phases of spinal cord injury such as spinal cord ischemia, cellular excitotoxicity, ionic dysregulation, and free-radical mediated peroxidation is far greater now than ever before, thanks to substantial laboratory research efforts. These discoveries are now being translated into the clinical realm and have led to targeted upfront medical management with a focus on tissue oxygenation and perfusion and include avoidance of hypotension, induction of hypertension, early transfer to specialized centers, and close monitoring in a critical care setting. There is also active exploration of neuroprotective and neuroregenerative agents; a number of which are currently in late stage clinical trials including minocycline, riluzole, AC-105, SUN13837, and Cethrin. Furthermore, new data have emerged demonstrating that the timing of spinal cord decompression after injury impacts recovery and that early decompression leads to significant improvements in neurological recovery. With this review we aim to provide a concise, clinically relevant and up-to-date summary of the topic of acute spinal cord injury, highlighting recent advancements and areas where further study is needed.

    ABSTRACT: There are several problems unique to large data sets. Large amounts of biased data are still biased and clinical significance is not always the same as statistical significance. Large number of predictors of outcome can confound conclusions, but there are several ways to manage wide ranging data sets including matching, regression, propensity scores, and randomization.

    ABSTRACT: A retrospective radiographic study. To investigate the reliability of using MRI to measure thoracic outlet parameters and whether supine MRI could supersede upright X-ray in measuring these parameters. In X-ray, overlapped soft and bony tissues make sternum contour invisible. Thus, measuring thoracic inlet alignment in X-ray may be inaccurate. MRI could clearly show anatomy around thoracic inlet. One hundred and twenty-four adolescents with idiopathic thoracolumbar/lumbar scoliosis were recruited. The visibility of T1 upper end plate and the upper end of sternum in the lateral standing X-ray films was rated. For patients with moderate or good clarity forT1 upper end plate and the upper end of sternum on X-ray films, thoracic inlet angle (TIA), T1 slope (T1S) and neck tilt (NT) were measured by 3 observers on standing X-ray films and supine MR images, respectively. Intraclass correlation coefficients were used to determine the intraobserver, interobserver and method reliability. Paired t test was performed to compare the measurements between the two methods. The correlation coefficients between the two methods were analyzed by regression analysis. The visibility of thoracic inlet region in X-ray films was unsatisfactory, whereas all the landmarks were clear in MR images. Only 81 patients' X-ray films were graded as moderate or good visibility in the thoracic inlet region. Both the intraobserver ICC and interobserver ICC were better in the MRI set than in the X-ray set in all the observers for three TI parameters. Paired t test demonstrated that no significant difference was noted in terms of TIA, T1S and TN (P=0.572, 0.203 and 0.637, respectively). Regression analysis demonstrated high correlation coefficients for TIA, T1S and NT (R=0.612, 0.629 and 0.722, respectively). MRI serves as a good substitute for X-ray scans with regard to the measurement of TI alignment, with superior reliability.

    ABSTRACT: Pilot single-centre, stratified, prospective, randomized, double-blinded, parallel-group, controlled study. To determine whether vertebral end-plate perforation after lumbar discectomy causes annulus reparation and intervertebral disc volume restoration. To determine that after six months there would be no clinical differences between the control and study group. Low back pain is the commonest long-term complication after lumbar discectomy. It is mainly caused by intervertebral disc space loss, which promotes progressive degeneration. This is the first study to test the efficiency of a previously described method (vertebral end-plate perforation) that should advocate for annulus fibrosus reparation and disc space restoration. We selected 30 eligible patients according to inclusion and exclusion criteria and randomly assigned them to the control (no end-plate perforation) or study (end-plate perforation) group. Each patient was evaluated in 5 different periods, where data was collected (preoperative and six months follow up MRI and functional outcome data (VAS back, VAS legs, Oswestry disability questionnaire). Intervertebral space volume (ISV) and height (ISH) were measured form the MRI images. Statistical analysis was performed using paired t-test and linear regression. P<0.05 was considered statistically significant. We found no statistically significant difference between the control group and the study group concerning ISV (P=0.6808) and ISH (P=0.8981) six months after surgery. No statistically significant differences were found between ODI, VAS back and VAS legs after six months between the two groups, however there were statistically significant differences between these parameters in different time periods. Correlation between the volume of disc tissue removed and preoperative versus postoperative difference in ISV was statistically significant (P=0.0020). The present study showed positive correlation between the volume of removed disc tissue and decrease in postoperative ISV and ISH. There were no statistically significant differences in ISV and ISH between the group with end-plate perforation and the control group six months after lumbar discectomy. Clinical outcome and disability were significantly improved in both groups three and six months after surgery.

    ABSTRACT: Spinal infections have historically been associated with significant morbidity and mortality. Current treatment protocols have improved patient outcomes through prompt and accurate infection identification, medical treatment, and surgical interventions. Medical and surgical management however remains controversial due to a paucity of high-level evidence to guide decision-making. Despite this, an awareness of presenting symptoms, pertinent risk factors, and common imaging findings are critical for treating spine infections. The purpose of this article is to review the recent literature and present the latest evidence-based recommendations for the most commonly encountered primary spinal infections: vertebral osteomyelitis and epidural abscess.

    ABSTRACT: Practitioners in the surgical and procedural specialties must prepare to differentiate themselves and the performance of their care delivery teams through the use of substantive, objective metrics along with the provision of service guarantees. As purchasers of surgical and procedural services move towards outcomes-focused Value Based Insurance Design (VBID) and purchasing, practitioners must move well beyond branding and process measure-focused "Value Based Purchasing" initiatives and be prepared to compete with transparency -- not just regionally, but nationally - based upon objectively established outcomes metrics.

    ABSTRACT: Minimally invasive transforaminal lumbar interbody fusion (MIS TLIF) is performed via tubular dilators thereby preserving the integrity of the paraspinal musculature. The decreased soft tissue disruption in the MIS technique has been associated with significantly decreased blood loss, shorter length of hospitalization, and an expedited return to work while maintaining comparable arthrodesis rates when compared to the open technique particularly in the setting of spondylolisthesis (isthmic and degenerative), recurrent symptomatic disc herniation, spinal stenosis, pseudoarthrosis, iatrogenic instability, and spinal trauma. The purpose of this article and the accompanying video is to demonstrate the techniques for a primary, single-level MIS TLIF.

    ABSTRACT: Spine fusion is a tool used in the treatment of spine trauma, tumors, and degenerative disorders. Poor outcomes related to failure of fusion, however, have directed the interests of practitioners and scientists to spinal biologics that may impact fusion at the cellular level. These biologics are used to achieve successful arthrodesis in the treatment of symptomatic deformity or instability. Historically, autologous bone grafting, including iliac crest bong graft harvesting, had represented the gold standard in spinal arthrodesis. However, due to concerns over potential harvest site complications, supply limitations, and associated morbidity, surgeons have turned to other bone graft options known for their osteogenic, osteoinductive, and/or osteoconductive properties. Current bone graft selection includes autograft, allograft, demineralized bone matrix, ceramics, mesenchymal stem cells, and recombinant human bone morphogenetic protein. Each pose their respective advantages and disadvantages and are the focus of ongoing research investigating the safety and efficacy of their use in the setting of spinal fusion. Rh-BMP2 has been plagued by issues of widespread off-label use, controversial indications, and a wide range of adverse effects. The risks associated with high concentrations of exogenous growth factors have led to investigational efforts into nanotechnology and its application in spinal arthrodesis through the binding of endogenous growth factors. Bone graft selection remains critical to successful fusion and favorable patient outcomes, and orthopaedic surgeons must be educated on the utility and limitations of various biologics in the setting of spine arthrodesis.

    ABSTRACT: A retrospective, observational study of prospectively collected outcomes. To investigate the long-term clinical course of anterior cervical discectomy and fusion with interbody fusion cages (ACDF-IFC) with lordotic tantalum implants and to correlate the radiological findings with the clinical outcomes, with special emphasis in the significance and influence of implant subsidence. Cage subsidence is the most frequently reported complication after ACDF-IFC. However, most reports fail to correlate cage subsidence with lower fusion rates, or with unsatisfactory clinical results. Forty-one consecutive patients with symptomatic degenerative cervical disc disease with failure of conservative treatment. All patients underwent one/two-level ACDF-IFC with lordotic tantalum implants. Mean follow-up of was 4.91 years. Final follow-up fusion rate was 96.96% (32/33). Interspace height (IH) at the affected levels was significantly incremented after implant insertion, and despite a gradual loss in the height occurred over time, final follow-up IH was significantly higher than preoperatively (P<0.0001). Anterior-IH and posterior-IH lost 55.8% and 76.2% of the initially incremented height respectively, with a final increase of 72% in the AIH-PIH height differential. Implant subsidence (>3 mm) occurred in 11 disc spaces (26.82%). Pre and postop-IH was significantly higher in the subsidence patients, however, there was no difference in final follow-up IH (P>0.05). Patients with ≥3 years of follow-up (n=29) did not demonstrate further significant subsidence beyond the second year. Regarding C1-C7 lordosis, segmental Cobb angle, cervical Visual Analogue Scale and Neck Disability Index questionnaires, no difference between patients with or without final follow-up endplate subsidence was encountered. Until fusion occurs, tantalum cage settlement into the vertebral body is to be expected. Further subsidence could be the result of segmental adaptative changes. Graft subsidence did not affect the clinical outcome in any of our patients during long-term follow-up. Occurrence of dynamical implant subsidence had a positive effect on cervical lordosis, especially at the posterior-IH.

    ABSTRACT: Retrospective chart review. Determine the long term efficacy of two-stage total en bloc spondylectomy (TES). TES is a well-described technique to achieve tumor-free margins, but it is a highly destabilizing procedure that necessitates spinal reconstruction. A two-stage anterior/posterior approach using has been shown to be biomechanically superior to the single-stage approach in achieving rigid fixation, but few clinical studies with long term outcomes exist. A retrospective review was performed on patients undergoing a two-stage TES for a spinal tumor between 1999 and 2011. Results were compared with those from a literature review of case series, with a minimum 2-year follow-up, reporting on a single-stage posterior-only approach for TES. Seven patients were identified (average follow up 52.7▒mo). Tumor location ranged from T1 to L3 with the following pathologies: metastasis (n=3), hemangioma (n=1), leiomyosarcoma (n=1), giant cell tumor (n=1), and chordoma (n=1). There were no significant surgical complications. All 7 patients had intact spinal fixation. There were no failures of the orthogonal fixation (pedicle screws or anterior fixation). Average mRS scores improved from 2.7 preoperatively to 0.7 at last follow-up. None of the patients in our series suffered local disease recurrence at last follow-up or suffered neurological deterioration. These results were comparable with those noted in the literature review of posterior-only approach, where 12% of patients experienced instrument failure. TES is a highly destabilizing procedure requiring reconstruction resistant to large multiplanar translational and torsional loads. A two-stage approach utilizing orthogonal vertebral body screws perpendicular to pedicle screws is a safe and effective surgical treatment strategy. Orthogonal spinal fixation may lower the incidence of instrumentation failure associated with complete spondylectomy and appears to be comparable to a single-stage procedure. However, larger prospective series are necessary to assess the efficacy of this approach versus traditional means.

    ABSTRACT: Retrospective study. To report the efficacy of anterior cervical decompression and fusion surgery as treatment method for cervicogenic headache. The exact diagnostic criteria and optimal treatment of cervicogenic headache is still under investigation. A total of 34 consecutive patients (mean age 55.8 y) with cervicogenic headache (in addition to cervical stenosis symptomatology) resistant to nonoperative treatment were treated by anterior cervical decompression and fusion from 1 up to 3 levels and were followed for at least 1 year. Clinical visual analog pain scale for headache, patient satisfaction index as well as radiographic examinations (flexion-extension radiographs and, when diagnosis of fusion status was uncertain, computerized tomography) were documented for all patients at regular intervals.Statistical comparisons of outcome measures between different time points of exams were performed. All patients reported relief of their cervicogenic headache with mean (range) visual analog pain scale scores 8.1 (3-9), 2.4 (0-4) and 3. 1 (0-5) preoperatively, at 2 months postoperatively and at the final follow-up, respectively. There was significant improvement (P<0.001) of visual analog pain scale score between before surgery and at 2 months postoperatively or at the last follow-up. Thirty patients (88%) reported satisfied with their treatment while 4 patients (12%) were not satisfied with surgery. No major surgical complication was seen and only one patient had symptomless pseudoarthrosis. Cervicogenic headaches when associated with cervical spinal stenosis of the subaxial spine can improve when stenosis is treated with anterior cervical discectomy and fusion.

    ABSTRACT: Cervical radiculopathy is a relatively common neurologic disorder resulting from nerve root dysfunction, which is often due to mechanical compression; however inflammatory cytokines released from damaged intervertebral discs can also result in symptoms. Cervical radiculopathy can often be diagnosed with a thorough history and physical examination, but an MRI or CT myelogram should be used to confirm the diagnosis. Due to the ubiquity of degenerative changes found on these imaging modalities, the patient's symptoms must correlate with pathology for a successful diagnosis. In the absence of myelopathy or significant muscle weakness all patients should be treated conservatively for at least 6 weeks. Conservative treatments consist of immobilization, anti-inflammatory medications, physical therapy, cervical traction, and epidural steroid injections. Cervical radiculopathy typically is self-limiting with 75-90% of patients achieving symptomatic improvement with non-operative care. For patients who are persistently symptomatic despite conservative treatment, or those who have a significant functional deficit surgical treatment is appropriate. Surgical options include anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior foraminotomy. Patient selection is critical to optimize outcome.

    ABSTRACT: Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) has become a popular alternative to traditional methods of lumbar decompression and fusion. When compared to the open technique, the minimally invasive approach can result in decreased pain and blood loss as well as a shorter length of hospitalization. However, the narrower working channel via the tubular retractor increases the difficulty of decortication and bone grafting. Therefore, recombinant human bone morphogenetic proteins (rhBMP-2) is often utilized (although this is off-label) to create a more favorable interbody fusion environment. Recently, the use of rhBMP-2 has been associated with excessive bone growth in an MIS-TLIF. If this bone growth compresses the neighboring neural structures, patients may present with either new or recurrent radicular pain. Computed tomographic (CT) imaging can demonstrate heterotopic bone growth extending from the disc space into either the ipsilateral neuroforamen or lateral recess which may result in the compression of the exiting or traversing root, respectively. The purpose of this article and the accompanying video is to demonstrate a technique for defining and resecting rhBMP-2 induced heterotopic bone growth following a previous MIS-TLIF.

    ABSTRACT: Cervical and lumbar spine arthrodesis is performed in the treatment of spine trauma, tumors, and degenerative disorders with an estimated 200,000 fusion procedures performed in the United States annually. Failure of fusion, or pseudarthrosis, has been reported at rates as high as 48% in multi-level posterolateral lumbar fusions. Achievement of arthrodesis is a strong predictor of outcome. This motivation has led to the consequential expansion of the spinal biologics arena, bringing forth new products, research, and applications. Surgeons and product manufacturers have introduced the application of various biologics, including allograft materials, ceramics, and growthfactor augmentation to aid in spine arthrodesis.
