Impaired breathing is a devastating result of high cervical spinal cord injuries (SCI) due to partial or full denervation of phrenic motoneurons, which innervate the diaphragm - a primary muscle of respiration. Consequently, people with cervical level injuries often become dependent on assisted ventilation and are susceptible to secondary complications. However, there is mounting evidence for limited spontaneous recovery of respiratory function following injury, demonstrating the neuroplastic potential of respiratory networks...

PURPOSE: The risk of neurological injury during vertebral column resection is high. In this study, we investigated the incidence and risk factors for neurological complications when treating spinal deformities by thoracic posterior vertebral column resection (PVCR). METHODS: Between 2008 and 2013, there were 62 consecutive patients (34 female patients and 28 male; the mean age: 16.3 years, range 6-46 years) treated with thoracic PVCR. We retrospectively reviewed the clinical records to obtain demographic and radiographic data, operative time, estimated blood loss (EBL, the ratio between circulating and lost blood), bleeding volume (the lost blood), number of vertebrae fused, number of vertebrae resected, usage of titanium mesh cage, and intraoperative neuromonitoring data...

OBJECTIVE Tethered cord syndrome is the clinical manifestation of an abnormal stretch on the spinal cord, presumably causing mechanical injury, a compromised blood supply, and altered spinal cord metabolism. Tethered cord release is the standard treatment for tethered cord syndrome. However, direct untethering of the spinal cord carries potential risks, such as new neurological deficits from spinal cord injury, a CSF leak from opening the dura, and retethering of the spinal cord from normal scar formation after surgery...

A major concern associated with ZIKV infection is the increased incidence of microcephaly with frequent calcifications in infants born from infected mothers. To date, postmortem analysis of the central nervous system (CNS) in congenital infection is limited to individual reports or small series. We report a comprehensive neuropathological study in ten newborn babies infected with ZIKV during pregnancy, including the spinal cords and dorsal root ganglia (DRG), and also muscle, pituitaries, eye, systemic organs, and placentas...

To generate voluntary forearm movements, the information that is encoded in the activity of the cortical neurons has to travel through the spinal cord and activate the skeletal muscles. The axons carrying these signals are tightly bundled together in the descending tracts that control the spinal circuitry innervating the forearm muscles. In this paper, we show that corticospinal tract (CST) signals can be used to predict forearm electromyographic (EMG) activities that are recorded during an isometric-pull task...

OBJECTIVES: Traumatic spinopelvic dissociation separates the spinal column from the pelvis, which usually creates lumbosacral kyphosis. We aimed to examine how the spinopelvic profiles changes after traumatic spinopelvic dissociation, and which are the relevant factors for the sagittal imbalance of the spine. DESIGN: Retrospective analysis. SETTING: Level I trauma center PATIENTS:: Thirty-nine consecutive patients who were diagnosed with traumatic spinopelvic dissociation and had a minimum 2-year radiological follow-up were included...

Acute traumatic spinal cord injury (SCI) is a devastating disease process affecting tens of thousands of people across the USA each year. Despite the increase in primary prevention measures, such as educational programs, motor vehicle speed limits, automobile running lights, and safety technology that includes automobile passive restraint systems and airbags, SCIs continue to carry substantial permanent morbidity and mortality. Medical measures implemented following the initial injury are designed to limit secondary insult to the spinal cord and to stabilize the spinal column in an attempt to decrease devastating sequelae...

Spinal trauma is a devastating event with a high morbidity and mortality. The rationale of imaging is to diagnose the traumatic abnormalities and characterize the type of injury, to estimate the severity of the lesions, to evaluate the potential spinal instability. In case of spinal instability, the goals of operative treatment are decompression of the spinal cord canal and stabilization of the disrupted vertebral column. Particularly, diagnostic imaging, mainly by CT and MR, has a main role in the post-treatment evaluation...

Thoracolumbar spondylodiscitis is a morbid disease entity, impacting a sick patient population with multiple comorbidities. Wherever possible, surgical measures in this population should limit the extent of soft tissue disruption and overall morbidity that is often associated with anteroposterior thoracolumbar decompression and fusion. The authors describe the rationale, technique, and use of the lateral lumbar transpsoas retroperitoneal approach in tandem with posterior decompression and instrumented fusion in the treatment of circumferential thoracolumbar spondylodiscitis with or without epidural abscesses...

Autologous cell transplantation is a promising strategy for repair of the injured spinal cord. Here we have studied the repair potential of mesenchymal stromal cells isolated from the human olfactory mucosa after transplantation into a rodent model of incomplete spinal cord injury. Investigation of peripheral type remyelination at the injury site using immunocytochemistry for P0, showed a more extensive distribution in transplanted compared with control animals. In addition to the typical distribution in the dorsal columns (common to all animals), in transplanted animals only, P0 immunolabelling was consistently detected in white matter lateral and ventral to the injury site...

Inducible nitric oxide synthase (iNOS) is a potent mediator of oxidative stress during neuroinflammation triggered by neurotrauma or neurodegeneration. We previously demonstrated that acute iNOS inhibition attenuated iNOS levels and promoted neuroprotection and functional recovery after spinal cord injury (SCI). The present study investigated the effects of chronic iNOS ablation after SCI using inos-null mice. iNOS(-/-) knockout and wild-type (WT) control mice underwent a moderate thoracic (T8) contusive SCI...

BACKGROUND: Spinal cord stimulation (SCS) has been shown to be effective in the management of certain neuropathic pain conditions, however, the underlying mechanisms are incompletely understood. In this study, we investigated repetitive SCS in a rodent neuropathic pain model, revealing long-lasting and incremental attenuation of hyperalgesia and a mechanism of action involving endocannabinoids. METHOD: Animals were implanted with monopolar electrodes at the time of partial sciatic nerve injury...

BACKGROUND: The recommended practice for over 30 years has been to routinely immobilize patients with unstable cervical spinal injuries using cervical spinal collars. It is shown that patients with Ankylosing spondylitis (AS) are four times more likely to suffer a spinal fracture compared to the general population and have an eleven-fold greater risk of spinal cord injury. Current protocols of spinal immobilization were responsible for secondary neurologic deterioration in some of these patients...

This article describes different types of vertebral fractures that affect the thoracolumbar spine and the most relevant contributions of the different classification systems to vertebral fracture management. The vertebral fractures types are based on the three columns model of Denis that includes compression, burst, flexion-distraction and fracture-dislocation types. The most recent classifications systems of these types of fractures are reviewed, including the Thoracolumbar Injury Classification and Severity score (TLICS) and the Arbeitsgemeinschaft für Osteosynthesefragen Spine Thoracolumbar Injury Classification and Severity score (AOSpine-TLICS)...
