Examination demonstrated mild spastic paraplegia, hypoesthesia with upper level at T5 and severe respiratory failure requiring assisted ventilation. Magnetic resonance imaging showed multiple thoracic masses compressing left lung, trachea, and spinal cord (). Surgical resection was performed. Through C5–T1 laminectomy, the intradural part of the neoplasia was completely removed, and the extradural part was enucleated as much as possible. After surgery, the respiratory function improved. Histologic pattern and S100 protein diffuse reactivity were consistent with plexiform schwannoma, a rare benign cutaneous variation of schwannoma . Although deep-seated...

However, NDI scores are unitless and do not have an intrinsic value that is comparable to other health status measures, and these scores have limited value in cost-utility analysis. The translation of disease-specific measures to Short Form-6 Dimensions (SF-6D) utility scores may be useful in cost-utility analysis.Purpose: The purpose of this study is to present a model for translating the NDI to SF-6D utility scores, permitting the use of NDI scores in the cost-utility analysis of cervical disorders.Study design/setting: A secondary analysis of a multicent...

We carried out a five-year prospective longitudinal radiological evaluation of patients using plain radiographs and CT scans. One year after surgery, 117 patients with an early successful fusion were selected for inclusion in the study. Radiological evaluation of interbody bone fusion was graded on a 4-point scale. The mean grades of all radiological and CT assessments increased in the five years after surgery, and differences compared to the previous time interval were statistically significant for three or four years after surgery. Because the grafted bone continues to mature for three years after surgery, the success o...

Performance-based deficits are seen mainly in tests of working memory and executive function. Neural correlates of executive function were investigated in 18 FM patients and 14 age-matched healthy controls during a simple Go/No-Go task (response inhibition) while they underwent functional magnetic resonance imaging (fMRI). Performance was not different between FM and healthy control, in either reaction time or accuracy. However, fMRI revealed that FM patients had lower activation in the right premotor cortex, supplementary motor area, midcingulate cortex, putamen and, after controlling for anxiety, in the right insular cortex and r...

Self-reported data on scoliosis from 64,578 twins in the Swedish Twin Registry were analysed. Prevalence, pair- and probandwise concordances and tetrachoric correlations in mono- and dizygotic same-sex twins were calculated. The relative importance of genetic variance, i.e. the heritability, and unique and shared environmental variance was estimated using structural equation modelling in Mx software. In addition, all twins in the twin registry were matched against the Swedish Inpatient Register on the primary diagnosis idiopathic scoliosis.

Then, a part of the ligament developed reactive granulation with small vessel formation. Finally, rupture of these small vessels caused repeated episodes of microbleeding, resulting in formation of a large cyst. The observation of degenerative ligament tissue, granulation formation, and microbleeding differentiated it from a synovial cyst or a ganglion cyst. The presence of hemosiderin deposits suggested chronic recurrent microbleeding. Taking all our findings together, we believe that our case of retro-odontoid cystic mass is different from the others that have been ...

Patients’ likability was manipulated by means of an evaluative conditioning procedure: pictures of patients were combined with either positive, neutral, or negative personal traits. Next, videos of the patients were presented to 40 observers who rated the pain. Patients were expressing no, mild-, or high-intensity pain. Results indicated lower pain estimations as well as lower perceptual sensitivity toward pain (i.e., lower ability to discriminate between varying levels of pain expression) with regard to patients who were associated with negative personal traits. The effect on pain estimations was only found with regard to patients expressing high-intensity pain. There was no effect on resp...

The importance of sagittal spinopelvic imbalance has been described for the developmental spondylolisthesis with isthmic lysis. However, it remains unclear if these mechanisms play a role in the pathogenesis of degenerative spondylolisthesis. The purpose of this study was to analyze the sagittal spinopelvic alignment, the body mass index (BMI) and facet joint degeneration in degenerative spondylolisthesis. A group of 49 patients with L4-L5 degenerative spondylolisthesis (12 males, 37 females, average age 65.9 years) was compared to a reference group of 77 patients with low back pain without spondy...

Those articles did not follow strict systematic review methods (such as those used by the Cochrane Collaboration Back Review Group), for they did not consistently provide detailed descriptions of search methods, inclusion and exclusion criteria, explicit assessments of study quality, and methods for synthesizing the evidence, as is expected for a systematic review. Nonetheless, the articles provided useful overviews of the current evidence supporting low back pain interventions by focusing on findings from high-quality systematic reviews, clinical practi...

He sustained a cerebral concussion, 21 bony fractures of his pelvis and sacrum, two rib fractures, a sternal fracture, a pneumothorax, a lacerated spleen, a ruptured bladder, a kidney contusion, transverse process lumbar spine fractures, and a C4 vertebral fracture that required neck bracing. On regaining consciousness, he could not move his numb left leg down where he felt a constant burning and crushing phantom pain. A magnetic resonance imaging of the lumbosacral spine () done 7 months after injury demonstrated multiple root avulsions affecting the exiting left L3–S1 nerve roots. Additional magnetic resonance imaging findings included clumping of the nerve roots in the cauda equina, empty pseudomeningoceles, and ar...

In the absence of postoperative signs of infection in patients with intraoperative contamination, there is no need of continuing antibiotic treatment. Postoperative kinetics of CRP and ESR showed to be the same in patients with and without intraoperative contamination. Higher levels of inflammatory markers were noted in complex spinal procedures where instrumentation was applied.

Excessively elevated FABs, both in patients and treating health care providers, have a negative impact on low back pain outcomes as they delay recovery and heighten disability. Fear-avoidance beliefs may be best understood when patients are categorized into subgroups of misinformed avoiders, learned pain avoiders, and affective avoiders as these categories elucidate potential treatment strategies. These include FAB-reducing information for misinformed avoiders, pain desensitizin...

The incidence of spring-back by level (ie, 117 laminae) was 6%, mainly occurring at the lower cervical spine. All spring-back closures were partial segmental closures, most commonly involving C5 and C6. Postoperative neurologic deficit was associated with spring-back closure; therefore, surgeons should adopt preemptive surgical measures to prevent the occurrence of such a complication.

The radiological measurement more commonly used is the dural sac cross-sectional area (DSCA). It has been recently shown that grading stenosis based on the morphology of the dural sac as seen on axial T2 MRI images, better reflects severity of stenosis than DSCA and is of prognostic value. This radiological prospective study investigates the variability of surface measurements and morphological grading of stenosis for varying degrees of angulation of the T2 axial images relative to the disc space as observed in clinical practice.

Although progression of neurologic deficits can be very slow, reduction of the spinal cord and repair of the defect are crucial to stop or reverse the deterioration. The outcome for patients who initially have Brown-Séquard syndrome is significantly better than for patients who presented with spastic paralysis. To our knowledge, this case study represents the first reported instance in which two separate anterior dural defects caused two levels of anterior spinal cord herniation.

Low-value service lines caring for expensive chronic conditions have been targeted for reform; for better or worse, the treatment of spine pain has been recognized as a representative example. Examining the Patient Protection and Affordable Care Act and existing pilot studies can offer a preview of how chronic care of spine pain will be sustained. Accountable care in an organization capable of collecting, analyzing, and reporting clinical data and operational compliance is forthcoming. Interdisciplinary spine pain centers integrating surgical and medical management, behavioral medicine, physical reconditioning, and societal reintegration represent the model of h...

The attending-level spine surgeon was statistically more specific in the evaluation of injury MRIs. The fluid-weighted STIR sagittal sequences are most useful in determining injury to the SSL, ISL, LF, and cervical facets capsules. Lumbar facet capsules are best evaluated with axial T2 MRI. The evaluation of the PLC on MRI can be accurately and efficiently interpreted by physicians at multiple levels of training, thus providing a key imaging modality in determining stability and need for stabilization.

The current case demonstrates the direct leakage of cement within the anterior spinal artery leading to an irreversible paralysis. The clinicians should be aware of such complications to happen and explain it to their patients.

The role of bone morphogenetic protein-2 (BMP-2) in bone formation has been extensively characterized over the last 30 years . The neuroscience field has also found significant involvement of BMPs in development, maturation, and repair of the peripheral nervous system (PNS) and central nervous system (CNS) . Although the direct influence of the PNS on bone homeostasis is well described, the interactions through which peripheral neurons may influence bone formation or repair remain to be fully defined . We would agree that further study of neuron-bone interaction could be highly significant for the orthopedic world. However, the potential role of BMPs in this interaction is largely unexplored.
