The course, treatment response and recovery potential following acute traumatic spinal cord injury (SCI) have been shown to differ depending on the neurological level of injury. However, there are limited data focused on thoracic-level injuries. A cohort of 86 patients from the prospectively maintained North American Clinical Trials Network (NACTN) SCI registry were identified and studied to characterize the patterns of neurological recovery as well as to determine rates of acute hospital mortality and pulmonary complications...

BACKGROUND: Spinal navigation has made significant advances in the last two decades. After initial experiences with pedicle screws in the thoracic and lumbar spine, technological improvements have resulted in their increased application in the cervical spine. Instrumentation techniques like cervical pedicle screws, lateral mass screws in C1 and transarticular screws C1/C2 have become standard due to the application of image guidance. TECHNIQUE: Different navigation techniques can be distinguished based on the type of imaging...

We report a rare case of familial inherited abnormal bone hyperplasia and ossification of the yellow ligament complicated by spinal stenosis. Complete reconstruction of stability and spinal cord decompression were achieved by posterior total laminectomy, fusion and internal fixation. We cannot clearly describe the inheritance characteristics of the disease. Although the risk of surgical treatment is high, it is still necessary to perform surgery, and the effect of the operation is substantial.

Spinal cord injury (SCI) is a devastating traumatic event which burdens the affected individuals and the health system. Schwann cell (SC) transplantation is a promising repair strategy after SCI. However, a large number of SCs do not survive following transplantation. Previous studies demonstrated that 17β-estradiol (E2) protects different cell types and reduces tissue damage in SCI experimental animal model. In the current study, we evaluated the protective potential of E2 on SCs in vitro and investigated whether the combination of hormonal and SC therapeutic strategy has a better effect on the outcome after SCI...

Diffuse idiopathic skeletal hyperostosis (DISH) is an increasingly prevalent ankylosing condition. Patients with DISH have an increased risk of spinal fractures, hypothetically the result of biomechanical changes in the spine. The aim of this study was to analyze the occurrence of biomechanical stress shielding in patients with DISH. To do this, bone mineral density (BMD) was measured longitudinally in the vertebral bodies of subjects with and without DISH and in the newly formed bone of subjects with DISH...

One blunt abdominal aortic disruption (BAAD) and one blunt thoracic aortic injury (BTAI) case are presented. Both aortic injuries were combined with spinal fractures. In the BAAD case the aortic pseudoaneurysm manifested just above the lumbar fracture while in the BTAI case the aortic injury appeared several vertebras below the thoracal fracture site, suggesting different mechanisms in the aortic wall damage. In both cases the aortic wall first was sealed, successfully, by endovascularly-placed stents, meaning the risks of open aortic reconstructive surgery could be avoided...
