BACKGROUND The axial skeleton is a common site for primary tumors and metastatic disease, with metastatic disease being much more common. Primary and metastatic spinal tumors have a diverse range of aggressiveness, ranging from benign lesions to highly infiltrative malignant tumors. METHODS The authors reviewed the results of articles describing the treatment and outcomes of patients with met...

In order to clarify the anatomical configuration of the spinal column in the supine position, we have examined T1-weighted sagittal midline magnetic resonance images of the spinal column in 20 healthy volunteers (11 men, nine women) in the supine position. The mean maximum angles of decline of the lumbar spinal canal in men and women were 12.6 (SD 3.9) degrees and 13.4 (3.3) degrees in the ceph...

We describe the serial MR imaging findings in a patient with spinal decompression sickness. In the acute phase, the spinal cord was swollen, with increased T2 signal in the posterior part of the column; 1 month later, marked contrast enhancement was noted in the same location; and 2 months later, the swelling and T2 signal had decreased. MR imaging may facilitate the early diagnosis of spinal d...

Management of patients with symptomatic spinal metastasis is designed to (1) relieve pain, and (2) restore or preserve neurologic function. The surgical strategy must include provisions for decompression of the dural sac and nerve roots, and stabilization of the spinal column. The optimal surgical approach, whether from in front or from behind is determined by a number of factors including (1) ...

We present a method of visualising spinal deformities in three dimensions using conventional radiographs and computer graphics. The shape of the spinal column can be determined from the anteroposterior and lateral radiographs and displayed in any projection. In patients with adolescent idiopathic scoliosis, the fundamental lesion, an abnormal lordosis, can be demonstrated without the need for a...

The neurons of the lateral spinal nucleus in the spinal cord of young adult rats were studied in transverse and longitudinal planes using the Golgi-Kopsch method and electron microscope. The perikarya were mainly polygonal or spindle shaped, and measured 20 to 35 μm in the longest diameter. They formed a dense column in the dorsolateral funiculus underneath the pial surface. The dendrites follo...

Trauma to the spinal column may cause a variety of clinical syndromes depending on the type and severity of the impact and bony displacement as well as secondary insults such as hemorrhage, ischemia, and edema. Complete spinal cord injury results in a transverse myelopathy, with total loss of spinal function below the level of the lesion. This insult is caused by either anatomic disruption of t...

Introduction: Germ cell tumors account for 3.5 % of pediatric and yolk sac are the most common pure malignant germ in children. Testis ovary sites involvement children older than 2 years. Case Presentation: A 20-month-old boy with a complaint limping was described this case report. Abdominal ultrasonography showed 52 × 50 mm solid abdominal mass. pelvic computed tomography scans left paraspinal...

Axial forces were applied between the shoulders and the skull of eight male Macaca mulatta monkeys. Forces from 556 to 1444 Newtons produced marked changes in blood pressure, heart rate and distraction of the cervical spinal column with minimal ligamentous disruption. Somatosensory evoked potentials recorded at the cortical and thalamic levels following dorsal column or peripheral nerve stimula...

BACKGROUND A loss of reduction due to inadequate support of the anterior column when using short-segment instrumentation to treat burst fracture and novel methods for support of the anterior column through a posterior approach to augment posterior instrumentation have been reported in the literature. We hypothesized that if anterior column support is an important adjunct to posterior short-segm...
