A pneumatocyst in the cervical spine is extremely rare and to our knowledge only a few reports have been published in the English literature. Although the etiology and natural course of vertebral body pneumatocyst is unclear, nitrogen gas accumulation is claimed. A 65-year-old-man was admitted to the emergency department with neck pain and numbness and incapacity in his both hands and fingers. ...

To determine whether resegmentation of somites forms the axial skeleton, we traced the development of the rostral and the caudal half of a somite during skeletogenesis in chick-quail chimeras by replacing the rostral or caudal half of a newly formed chick somite with that of a quail somite. The rostral half-somite transplant formed the caudal half of the vertebral body, the entire spinous proce...

Kyphoplasty is a technique that tries to recover the height of the fractured vertebral body and support this fracture with the injection of cement into the vertebral body. T...

Human lumbar vertebrae support the weight of the upper body. Loads lifted and carried by the upper extremities cause significant loading stress to the vertebral bodies. It is well established that trauma-induced vertebral fractures are common especially among elderly people. The aim of this study was to investigate the morphological factors that could have affected the prevalence of trauma-rela...

osteosarcoma may rarely originate from the axial bones such as pelvis or vertebrae. in some pelvic and most vertebral primary tumors, resection often is not possible completely. in general, these tumors cannot be resected with negative margins so they need additional radiotherapy and chemotherapy, but results are unfavourable because of poor local control and high incidence of distant metastase...

OBJECTIVE The objective of this study was to investigate the morphologic characteristics between the vertebral body and the regions of the cervical and thoracic spinal cords where each rootlets branch out. METHODS Sixteen adult cadavers (12 males and 4 females) with a mean age of 57.9 (range of 33 to 70 years old) were used in this study. The anatomical relationship between the exit points of...

BACKGROUND AND PURPOSE Patients successfully treated with vertebroplasty often return with new pain caused by a new vertebral body fracture. The new fractures often are adjacent to the vertebral bodies that were initially treated. In our clinical work, we have observed that cement leakage into the disk increases the risk of new fracture of the adjacent vertebral body. This study analyzed the ri...

BACKGROUND Osteoporotic vertebral compression fracture is a serious complication of osteoporosis. Various vertebral kyphoplasty surgeries, which have their own unique features, are commonly used for osteoporotic vertebral compression fracture. Based on the anatomic property of the thoracolumbar vertebral pedicle that its horizontal diameter is twice that of the vertical diameter, we designed Ja...

Introduction: Vertebral collapse is associated with breakdown of vertebra resulting in decrease in height of vertebral body. Magnetic Resonance Imaging is well known method to evaluate bone and bone marrow diseases, one of the reliable markers to differentiate between benign and malignant compressive fractures and certain characteristics which aids in early differentiation of benign and maligna...
