BACKGROUND AND PURPOSE Adjacent fracture formation after percutaneous vertebroplasty has been reported in literature. The purpose of this study was to determine whether intervertebral disk extravasation is related to adjacent fracture formation in low-volume cement-filling vertebroplasty. METHODS A retrospective analysis of 308 patients having vertebroplasty was undertaken. Anteroposterior an...

Retrospective evaluation was made of four patients with tuberculous spondylitis who had been studied by MR with T1- and T2-weighted images in the sagittal plane and spin-density-weighted images in the axial plane. Evaluation was made of the distribution of abnormal signals within the body and posterior elements of the vertebrae, the intervertebral disk, and the associated paraspinal and epidura...

BACKGROUND Diabetes mellitus is a multi-organ disorder affecting many types of connective tissues, including bone and cartilage. Certain skeletal changes are more prevalent in diabetic patients than in non-diabetic individuals. A possible association of diabetes mellitus and lumbar spinal stenosis has been raised. OBJECTIVES To compare the prevalence of diabetes mellitus in patients with spin...

The importance and role of computed tomography (CT) are discussed on the basis of 36 cases of vertebral osteomyelitis. The bone images themselves, the detection of lumbar disk hypodensity, and the exploration of soft paraspinal regions in the search for an abscess are factors that contribute to the superiority of this method in difficult cases. In cases where the diagnosis is already known, CT ...

PURPOSE To document the pattern of enhancement and morphologic changes on MR images that occur in the intervertebral disk and adjacent vertebral bodies after diskectomy and to correlate the presence of intervertebral disk enhancement with the preoperative and postoperative clinical findings. METHODS Preoperatively, and at 3 months and 6 months after surgery, 94 adults who had first-time surge...

We report a case of an unusually prominent persistent notochordal canal involving the T12-L5 vertebrae. This rare anatomic variation was discovered as an incidental finding in a patient with lymphoma undergoing MR imaging for evaluation of back pain. MR images showed a vertically oriented canal contiguous with the intervertebral disks traversing the anterior aspect of each affected vertebral bo...

Scheuermann’s disease (juvenile kyphosis dorsalis) is a structural kyphosis of the thoracic spine initially described by Scheuermann in 1921. It occurs commonly in adolescents (0.4-8.3% of the general population). It is characterized by irregularities of the vertebral end plates, the presence of Schmorl’s nodes, disk-space narrowing, and vertebral wedging. Scheuermann’s disease is rarely associ...

BACKGROUND AND PURPOSE Literature regarding clinical pain syndromes associated with acute, traumatic Schmorl's nodes (SNs) is limited. Our purpose was to determine whether an SN could be related to a previous traumatic event producing either acute SN or a vertebral endplate fracture. METHODS Two neuroradiologists independently reviewed initial and follow-up MR examinations of 14 patients with...
