BACKGROUND: Subsidence and late fusion are commonly observed in anterior subtotal corpectomy and reconstruction for treating thoracolumbar burst fractures. The subsidence rate of this surgical method was reported from 19.6% to 75% in the literatures, which would cause treatment failure. Thus, an improvement of anterior surgery technique should be studied to reduce these complications. MATERIALS AND METHODS: 130 patients of thoracolumbar burst fractures treated by minimal corpectomy, decompression and U cage, between January 2009 and December 2010 were included in this study...

INTRODUCTION: Surgical management for lumbar stenosis is generally safe and provides significant improvements in pain, disability, and function. Successful lumbar decompression hinges on removing an appropriate amount of lamina and other compressive pathology in the lateral recess. Too little bony decompression can result in persistent pain and disability, while over resection of the pars and/or facets may jeopardize spinal stability. CASE REPORT: In this unique report, we present for the first time an acute iatrogenic grade 4 L5-S1 spondylolisthesis distal to a L3-5 laminectomy and circumferential instrumented fusion due to bilateral iatrogenic L5 pars fractures and its management and clinical outcomes after revision operation...

BACKGROUND: The contribution of preoperative embolization in reducing intraoperative blood loss and its clinical importance are unclear. So, we aimed to compare the perioperative clinical outcomes based on whether preoperative embolization was performed and assess the role and safety of preoperative embolization in metastatic spinal cord compression (MSCC) patients. METHODS: We enrolled 52 patients (men, 37; women, 15) who underwent palliative decompression for MSCC...

INTRODUCTION: Fibrinogen may be reduced following traumatic injury due to loss from haemorrhage, increased consumption and reduced synthesis. In the absence of clinical trials, guidelines for fibrinogen replacement are based on expert opinion and vary internationally. We aimed to determine prevalence and predictors of low fibrinogen on admission in major trauma patients and investigate association of fibrinogen levels with patient outcomes. PATIENTS AND METHODS: Data on all major trauma patients (January 2007-July 2011) identified through a prospective statewide trauma registry in Victoria, Australia were linked with laboratory and transfusion data...

Degenerative lumbosacral stenosis is a common disease in dogs characterised by intervertebral disc herniation, loss of disc height and stenosis. Decompressive dorsal laminectomy and partial discectomy can cause spinal instability and worsen foraminal stenosis. Pedicle screw and rod fixation (PSRF) with an intervertebral body cage allows for distraction and restoration of disc height and restores foraminal apertures. The aim of this study was to evaluate the ex vivo biomechanical properties of a titanium intervertebral cage alone and in combination with PSRF in the lumbosacral spine of dogs...

Most spinal cord injury is seen with trauma. Nontraumatic spinal cord emergencies are discussed in this chapter. These myelopathies are rare but potentially devastating neurologic disorders. In some situations prior comorbidity (e.g., advanced cancer) provides a clue, but in others (e.g., autoimmune myelopathies) it may come with little warning. Neurologic examination helps distinguish spinal cord emergencies from peripheral nervous system emergencies (e.g., Guillain-Barré), although some features overlap...

Tumoral calcinosis is characterized by tumor-like deposition of calcium in periarticular soft tissue. Spinal involvement is rare, and perioperative diagnosis of tumoral calcinosis can be difficult because lesions may be confused with bony neoplasms. Symptoms of tumoral calcinosis result from bony involvement and/or direct compression of surrounding anatomical structures, for which treatment with surgical decompression can be highly successful. The craniovertebral junction is rarely affected by tumoral calcinosis, and patients with this condition may present with distinct symptoms...

Lumbar spinal stenosis is most often a degenerate condition observed in the older population. We describe the case of a lady with typical claudicant symptoms with an unusual cause of stenosis identified at the time of her decompressive surgery. On review of the literature this is only the second case of osteochondral loose body as a cause for lumbar spinal stenosis and thus remains a rare phenomenon.

Background Primary spinal epidural lymphoma (PSEL) is one of the rarest categories of tumors. Spinal cord compression is an uncommon primary manifestation and requires to be treated with surgery for the purpose of diagnosis and decompression. Case Presentation A 45-year-old man presented with a new onset thoracic pain and progress to an anterior spinal syndrome with hypoesthesia and loss of thermalgesia. Magnetic resonance image showed a paravertebral mass that produces medullary compression at T3. The patient was taken up to surgery, where the pathology examination showed a diffuse large B-cell lymphoma...

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...

BACKGROUND: Interspinous spacer/implants like the Device for Intervertebral Assisted Motion (DIAM™) are controversially yet commonly used in the surgical treatment of lumbar degenerative pathologies. Criticism is based on ill-defined indications, lack of superiority over decompression, and a poorly understood mechanical effect. Yet, continued use by surgeons implies their perceived clinical merit. We examined radiographic spinal alignment for 12 months, and pain and function for 24 months, after DIAM-augmented surgery to improve the understanding of the mechanical effect relating to clinical outcomes in patients...

PURPOSE: The nerve root sedimentation sign (SedSign) is a magnetic resonance imaging (MRI) sign for the diagnosis of lumbar spinal stenosis (LSS). It is included in the assessment of LSS to help determine whether decompression surgery is indicated. Assessment of the reversibility of the SedSign after surgery may also have clinical implications for the decision about whether or not a secondary operation or revision is needed. This study investigated if lumbar decompression leads to a reversal of the SedSign in patients with LSS and a positive SedSign pre-operatively; and if a reversal is associated with more favourable clinical outcomes...
