It is well established that diagnostic X-ray practices must be optimised to keep patient radiation dose as low as compatible with providing the diagnostic information required. For effective optimisation of diagnostic exposures, the International Commission on Radiological Protection (ICRP) introduced the concept of diagnostic reference levels (DRLs) in 1996. The present study aimed to carry out an extensive dose survey of diagnostic radiography installations in the Uttarakhand region of India to establish local DRL Values for the different diagnostic practices...

OBJECTIVE The treatment of cervical spinal metastases represents a controversial issue regarding the type, extent, and invasiveness of interventions. In the lumbar and thoracic spine, kypho- and vertebroplasties have been established as minimally invasive procedures for patients with metastases to the vertebral bodies and without neurological deficit. These procedures show good results with respect to pain reduction and low complication rates. However, limited data are available for kypho- and vertebroplasties for cervical spinal metastases...

BACKGROUND: Postural rehabilitation emphasizing on motor control training of segmental spinal movements has been proposed to effectively reduce the scoliotic spinal deformities in adolescent idiopathic scoliosis (AIS). However, information regarding the impairments of segmental spinal movement control involving segmental spinal stabilizers in adolescent idiopathic scoliosis remains limited. Examination of segmental spinal movement control may provide a window for investigating the features of impaired movement control specific to spinal segments that may assist in the development of physiotherapeutic management of AIS...

INTRODUCTION: Pedicle screw stabilization, the standard technique in the thoracic and lumbar spine, is increasingly used in the cervical spine. Initial studies on the use of anterior pedicle screws (ATPS) in the cervical spine have been recently published. ATPS use has theoretical advantages over posterior stabilization. We have already established a 3D-fluoroscopy navigation setup in a study of artificial bones. The aim of the current study was to evaluate the positioning quality/accuracy of ATPS introduced to human specimens...

BACKGROUND: The current American Society of Regional Anesthesia (ASRA) guidelines recommend discontinuing anti-thrombotic therapy prior to any interventional spine procedures to decrease the incidence of bleeding complications. However, discontinuing anti-thrombotics may pose considerable danger in terms of cerebrovascular and cardiovascular events. Recent evidence suggests that some spinal interventions may still be performed safely with anti-thrombotics on board and some practitioners thus elect to continue certain anti-thrombotics for these procedures...

BACKGROUND: Spinal cysticercosis has been reported in 0.7%-3.0% of patients with neurocysticercosis. Most patients with spinal cysticercosis have a coexisting intracranial disease. Most often this intracranial disease manifests as intradural extramedullary lesions involving thoracic and lumbar regions or intramedullary lesions. Intradural extramedullary primary spinal cysticercosis manifesting as cervical myelopathy is extremely rare and has not been reported to date. CASE DESCRIPTION: A 56-year-old man from the northeastern part of India presented with progressive spastic quadriparesis...

Producing a consistent and reproducible contusive spinal cord injury (SCI) is critical to minimizing behavioral and histological variabilities between experimental animals. Several contusive SCI models have been developed to produce injuries using different mechanisms. The severity of the SCI is based on the height that a given weight is dropped, the injury force, or the spinal cord displacement. In the current study, we introduce a novel mouse contusive SCI device, the Louisville Injury System Apparatus (LISA) impactor, which can create a displacement-based SCI with high injury velocity and accuracy...

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...

BACKGROUND CONTEXT: The process of linear growth is driven by axial elongation of both long bones and vertebral bodies and accomplished by enchondral ossification. Differences in regulation between the two skeletal sites are mirrored clinically by the age course in body proportions. Whereas growth plates in long bones can easily be discriminated, vertebral growth plates are part of the cartilaginous endplate, which typically shows important species differences. PURPOSE: To describe and compare histological, histomorphometric and regulatory characteristics in the growth plates of the spine and long bones in a porcine model...
