Solitary Bone Cyst in the Lumbar Spine: Case Report and Literature Review.

Introduction: To describe a rare case of solitary bone cyst in the vertebral body of the lumbar vertebra in an adult patient. The solitary bone cyst is defined as a cystic lesion with liquid content. Few cases have been described in the vertebral location without preference for the posterior arch or vertebral body.

A descriptive study on the adjacent segment degeneration related signs following a lumbar fusion procedure.

Background: Adjacent segment degeneration (ASD) is a frequent complication following vertebral fusion procedures and is defined as the condition where patients recover after the initial procedure but develop compatible symptoms with radiological injuries in the segments adjacent to the fused ones at a later stage. The objective of the study was to describe the frequency and analysis of ASD related signs following a lumbar fusion procedure.

Methods: Observational descriptive retrospective study on patients with degenerative or instability conditions, operated on by posterolateral or circumferential lumbar fusion procedure.

Long-Term Reliability of the Two-Segment Fusion Technique in the Treatment of Thoracolumbar Fractures Using Screws in the Fractured Vertebra.

Background: There is some controversy about which is the best approach, decompression technique and number of fixed levels in the surgical treatment for burst thoracolumbar fractures. Without a neurological injury, correcting thoracolumbar kyphosis and preventing mechanical failure should be the main concerns. The two-segment short fusion with screws at fractured vertebra by posterior approach was performed in 64 patients.

Sagittal Deformity Correction in a Patient Suffering From Diffuse Idiopathic Skeletal Hyperostosis Who Previously Underwent a Total Hip and Bilateral Knee Replacement.

Introduction: Physiological aging frequently leads to degenerative changes and spinal deformity. In patients with hypolordotic fusions or ankylosing illnesses such as diffuse idiopathic skeletal hyperostosis or ankylosing spondylitis, compensation mechanisms can be altered causing severe pain and disability. In addition, if a total hip replacement and/or knee replacement is performed, both pelvic and lower limbs compensation mechanisms could be damaged and prosthetic dislocation or impingement syndrome could be present.

Secondary thoracolumbar deformity and sagittal imbalance due to osteoporosis in a young man with Cushing's disease: A case report.

Introduction: To describe an unusual case of Cushing's disease with spontaneous axial pain due to multiple consecutive vertebral fractures which led to secondary deformity that required surgical treatment.

Presentation Of Case: A 43-year-old man was referred to our service with back pain without previous trauma. He was diagnosed of refractory arterial hypertension and we observed centripetal obesity during exploration.

An Unusual Case of Radicular Pain Caused by Bilateral Lumbar Synovial Cyst: A Case Report and Review of the Literature.

Introduction: Spinal synovial cysts (SSCs) constitute an uncommon degenerative lesion of the spine. They are usually asymptomatic but they may also cause symptoms of variable severity. SSCs are benign growths adjoining the facet joints that may induce low back pain, lumbar radiculopathy, and neurological deficit.

Emergency stabilisation by single-stage posterior transpedicular approach for treatment of unstable lumbar spine fracture with neurological injury.

Management of unstable thoracolumbar fractures remains controversial. Furthermore, when these are accompanied by related neurological injury, the choice of approach, decompression technique and timing of the intervention could have a neuroprotective effect. In terms of site, the lumbar spine represents only 1.

Thoracic pedicle subtraction osteotomy for correction of proximal junctional kyphosis after surgery for adolescent idiopathic scoliosis: A case report.

Introduction: Complications in the upper thoracic spine are not uncommon after corrective surgery for deformities in adults and adolescents. Proximal junctional failure has been linked to structural osseous or ligamentous failure and proximal junctional kyphosis has been described as an increase in preoperative proximal kyphosis.

Case Description: A 20-year-old male patient intervened after atypical development of idiopathic scoliosis, with rapid progression nearing skeletal maturity.

Radiographic and Functional Results following Subtalar Arthroereisis in Pediatric Flexible Flatfoot.

Introduction: Flexible flatfoot (FFF) is one of the most common skeletal disorders in children. In symptomatic patients who do not respond to conservative measures, surgery may be an option. Subtalar arthroereisis consists of limiting excessive eversion of the subtalar joint through different types of implants.

Risk factors related to adjacent segment degeneration: retrospective observational cohort study and survivorship analysis of adjacent unfused segments.

Object: Adjacent segment disease (ASD) has been described as a frequent complication after a lumbar spinal fusion procedure, though its incidence and the factors related to its appearance are not well established. The radiographic signs that identify ASD in unfused segments may be a consequence of biomechanical changes induced by the fusion procedure. This study sought to analyse the incidence of radiographic changes (radiographic ASD) in all adjacent unfused segments, the clinical changes that require a second procedure (clinical ASD), and the risk factors of their appearance evaluated at different follow-up times.

The impact of urgent intervention on the neurologic recovery in patients with thoracolumbar fractures.

Background: We carried out an observational longitudinal retrospective study between 2000 and 2009 in 28 patients who underwent surgery for unstable vertebral fractures with neurologic deficits.

Methods: For the statistical analysis, we used the Chi-test to compare proportions in independent groups and the exact Fisher test and the Wilcoxon test for repeated measures, and we compared the mean values using the Mann-Whitney U test at a significance level of P<0.05.

Free disease long-term survival in primary thoracic spine leiomyosarcoma after total en bloc spondylectomy: A case report.

Introduction: To describe an unusual primary vertebral leiomyosarcoma in thoracic spine.

Presentation Of Case: An isolated lesion of the T11 vertebra in a 62-year-old woman with no neurologic deficit is reported. Imaging findings indicated a nonspecific high-grade malignant lesion.

Spinal Epidural Hematoma Related to Vertebral Fracture in an Atypical Rigid Diffuse Idiopathic Skeletal Hyperostosis: A Case Report.

Introduction: Spinal epidural hematoma (SEH) is a rare disease that causes cord compression and neurologic deficit. Spontaneous SEH is related to minor trauma, bleeding disorders, and anticoagulant medications. Posttraumatic SEH has been associated with low-energy spine hyperextension injuries in patients with ankylosing spinal disorders such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis (DISH).

Unusual Spinal Epidural Lipomatosis and Lumbosacral Instability.

Introduction. Epidural lipomatosis is most frequently observed in patients on chronic steroid treatment. Only a few idiopathic epidural lipomatosis cases have been described.
