BACKGROUND: Muscle imbalance has been suggested as implicated in the pathology of adolescent idiopathic scoliosis (AIS). The specific "pathomechanic" role of the paravertebral muscles as being scoliogenic (inducing scoliosis) or counteracting scoliosis in the initial development and maintenance of this spinal deformity has yet to be clarified in humans. In the present study, we investigated the radiographic changes of temporal paralysis using botulinum toxin A as localized injection therapy (ITB) in the psoas major muscle in AIS patients...

IgG4-related disease (IgG4-RD) is a systemic fibroinflammatory disease characterized by tumefactive lesions in various organ systems, including the lungs. Clinical and radiological manifestations of IgG4-RD are relatively non-specific, and we report a case highlighting the importance of histopathological confirmation in cases of suspected IgG4-related lung disease. A 44-year-old male with significantly elevated serum IgG4 levels, patchy consolidation on thoracic CT imaging, and cough was referred with suspected IgG4-related lung disease...

BACKGROUND CONTEXT: Many different correction methods have been reported to treat severe and rigid scoliosis. In the past, anterior/posterior spinal fusion (APSF), which included an anterior release followed by posterior instrumented fusion was widely applied. In recent years, anterior/posterior vertebral column resection (APVCR) is used to treat severe and rigid scoliosis. PURPOSE: To compare the clinical results of APSF and APVCR for severe and rigid scoliosis...

Mild-moderate blunt chest trauma is defined as a blunt chest trauma that is not caused by a high-energy mechanism, causing thoracic tenderness with or without rib fractures and that has no immediate life-threatening consequences for the patient. It is a frequent clinical situation in the emergency department. The most common radiological techniques that are used in this context are chest X-ray and thoracic computed tomography (CT). The CT scan is set as the gold standard. However, there are no current clinical-radiological guidelines that establish the adequacy of the requests of the CT scan...

Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity...

BACKGROUND: Short-segment pedicle-screw instrumentation is frequently used to stabilize thoracolumbar burst fractures. A recognized disadvantage of this procedure is recurrent kyphosis from intervertebral disc creep into the fractured central endplate. Balloon Assisted Endplate Reduction (BAER) using Tricalcium Phosphate bone cement (TCP) enables elevation of the centrally depressed endplate. Our objective was to evaluate the bone-tissue response to TCP and to analyse whether BAER using TCP can prevent recurrent kyphosis after removal of the instrumentation...

BACKGROUND: Thoracic hyperkyphosis can display pathological deterioration, resulting in either hyperlordotic cervical compensation or sagittal malalignment. Various techniques have been described to treat fixed malalignment. Pedicle subtraction osteotomy (PSO) is commonly used in the lumbar spine and frequently limited to the distal thoracic spine. This series focuses on the surgical specificities of proximal thoracic PSO, with clinical and radiological outcomes. OBJECTIVE: To report the surgical specificities and assess the clinical and radiological outcomes of proximal thoracic osteotomies for correction of rigid kyphotic deformities...

OBJECTIVE Spinal deformity has become a well-recognized complication of intramedullary spinal cord tumor (IMSCT) resection. In particular, laminectomy can result in biomechanical instability caused by loss of the posterior tension band. Therefore, laminoplasty has been proposed as an alternative to laminectomy. Here, the authors describe the largest current series of pediatric patients who have undergone laminoplasty for IMSCT resection and investigate the need for surgical fusion after both laminectomy and laminoplasty...

REVIEW
Ze-Rui Zhao, Rainbow W H Lau, Calvin S H Ng
Cone-beam computed tomography provides unparalleled real-time imaging of the patient within the hybrid theater, which can be used for simultaneously diagnosing and localizing small pulmonary lesions for resection. Hybrid theater can guide more precise placement of electromagnetic navigation bronchoscopy tools, thereby increasing the diagnostic yield in biopsy procedures while reducing diffusion artifact in dye marking for nodule localization. Furthermore, hook-wires implantation that is widely used to assist in lesion localization for uniportal thoracoscopic surgery can take place in the hybrid suite, eliminating the common complications and discomfort associated with the conventional workflow carried out in the radiology suite...

The CC chemokine ligand 18 (CCL18) is produced by alveolar macrophages in patients with fibrosing lung disease and its concentration is increased in various fibrotic lung diseases. Furthermore CCL18 is elevated in several malignancies as it is produced by tumor associated macrophages. In this study we aimed to analyze the role of CCL18 as a prognostic biomarker for the development of early radiation induced lung toxicity (RILT), i.e. radiation pneumonitis after thoracic irradiation and its significance in the course of the disease...
