Localization of the correct vertebral level for surgical entry during lumbar hernia surgery is not straightforward. In this paper we develop and evaluate a solution using free-hand 2D ultrasound (US) imaging in the operation room (OR). Our system exploits the difference in spinous process shapes of the vertebrae. The spinous processes are pre-operatively outlined and labeled in a lateral lumbar X-ray of the patient. Then, in the OR the spinous processes are imaged with 2D sagittal US, and are automatically segmented and registered with the X-ray shapes...

Staphylococcus aureus bloodstream infections (SABSI) are associated with high morbidity and mortality. The Toll-like receptor 2 (TLR2) and Toll-interacting protein (TOLLIP) are important in recognition and regulation of human innate immunity response to S. aureus. Single nucleotide polymorphisms (SNPs) in the TLR2 and TOLLIP encoding genes have been associated with disease, including BSI. The aim of this study was to examine potential associations between a selection of SNPs in the genes encoding TLR2 and TOLLIP, and predisposition, severity, and outcome of SABSI...

BACKGROUND: Currently, many scholars are concerned about the treatment of postoperative infection; however, few have completed multivariate analyses to determine factors that contribute to the risk of infection. Therefore, we conducted a multivariate analysis of a retrospectively collected database to analyze the risk factors for acute surgical site infection following lumbar surgery, including fracture fixation, lumbar fusion, and minimally invasive lumbar surgery. METHODS: We retrospectively reviewed data from patients who underwent lumbar surgery between 2014 and 2016, including lumbar fusion, internal fracture fixation, and minimally invasive surgery in our hospital's spinal surgery unit...

BACKGROUND CONTEXT: Single-stage surgery is usually applied to improving the symptoms of coexisting cervical and lumbar stenosis. In most cases, patients' willingness, surgery affordability, surgical trauma, surgical complications and patients' tolerance to surgery all limit the application of single-stage surgery. For patients who cannot receive single-stage surgery, we hope that we can find out by weighing up merits and flaws of the two surgical sites in order to make decision of prioritize one of the two surgery, so as to bring more benefits to the patients...

Lumbar facet cysts are frequently found in patients with facet degeneration and segmental instability. When the facet cyst is localized in the neural foramina and lateral recess or becomes large, it can cause radiculopathy or neurogenic claudication. These symptomatic cysts are typically treated interventionally with drainage and a corticosteroid injection or attempts via overinflation to rupture the cyst; however, these procedures have a significant recurrence rate (up to 50%) and often need to be repeated or lead to lumbar surgery if unsuccessful...

BACKGROUND: Lower back pain is a very common symptom and treatment strategies vary according the severity and duration of illness. Surgical approaches are becoming increasingly popular with the advent of new and less invasive technologies; however, treatment outcomes are not yet well established on a population-based level. Taiwan's National Health Insurance Research Database (NHIRD) is longitudinal and includes 98% of the population since its inception in 1995. The database includes the ICD 9...

BACKGROUND AND OBJECTIVE: When a cervical or thoracic benign intradural spinal tumor (BIST) coexists with lumbar degenerative diseases (LDD), diagnosis may become difficult. Symptoms of BIST-myelopathy may be mistaken as related to LDD. Worse, an unnecessary lumbar surgery could be performed. This study was conducted to analyze cases in which an erroneous lumbar surgery was undertaken in the wake of failure to identify BIST-associated myelopathy. METHODS: Cases were found in a hospital database...

Guillain-Barré syndrome is a rare autoimmune condition characterized by ascending motor weakness of the extremities that can ascend to the diaphragm, causing substantial morbidity and mortality. This case report describes a 57-year-old man who exhibited characteristics of Guillain-Barré syndrome 9 days after undergoing lumbar fusion at L3-S1. The diagnosis was based on the patient's ascending motor weakness and areflexia and was confirmed with electromyography. The patient progressed to respiratory failure, requiring mechanical ventilation...

Benign low back pain is frequent in the lucratively active population. Degenerative changes are considered the most frequent causes. The identification of pain generators remain challenging. Bone marrow lesions, Modic changes, are frequently associated with benign low back pain, mostly type 1. The etiology of Modic changes is unknown, both infectious and autoimmune mechanisms have been suggested. Despite the strong association of Modic changes with low back pain it is not clear whether lumbar surgery (lumbar fusion, total disc replacement) has any role in the management of these patients...

BACKGROUND: Our previous study demonstrated that selective nerve root block (SNRB) can influence decision-making in lumbar surgery by guiding the selection of nerve roots targeted for decompression in diagnostic doubt patients (DDPs). However, further studies were needed to determine whether this selective decompression (SD) procedure would result in similar clinical outcomes and reduce the perioperative parameters and postoperative complications as compared to the non-selective decompression (NSD) procedure...

Intradural spinal arachnoid cysts (ISACs) have been reported in the current literature as either an idiopathic disease or exceedingly rare sequelae after lumbar puncture, spinal trauma, or meningitis. Other studies have more appropriately termed the iatrogenic pathology as a spinal subdural extra-arachnoid hygroma (SSEH), as there is not often a clear cyst wall as in a true arachnoid cyst. However, to the best of our knowledge, none of the previous studies described an SSEH following uncomplicated posterior lumbar surgery, as they have previously involved clear durotomies during the initial operation...
