The etiology of idiopathic scoliosis is still a matter of debate as its common cause had not been found. But some basic principles in its initiation and progression do exist. The curvature of the spine is always accompanied by rotation of the vertebrae and rib cage as ribs are connected by intercostal muscles and cannot spread apart on the convex side when the spine bends. The rib cage rotates ...

Although the radiological appearances of rheumatoid arthritis of the cervical spine are now well recognized there is little information on the changes, if any, to be expected in the dorsal and lumbar spine. We have encountered only three papers dealing with rheumatoid arthritis in this part of the spine. Baggenstoss, Bickel, and Ward (1952) and Lorber, Pearson, and Rene (1961) have reported rhe...

Degenerative cervical spondylolisthesis (DCS) had previously been thought to be a rare condition when compared to degenerative lumbar spondylolisthesis. However, with consequences from untreated spondylolisthesis including pain, myelopathy, and radiculopathy, it has now become recognized as an under-studied condition which may be more prevalent than previously thought. Spondylolisthesis of the ...

Background: Spinal cord injury (SCI) is one of the main causes of severe disability and mortality following trauma. Complications and outcomes of patients with spine trauma, especially those who undergo surgery, are a less divulged topic in Iran. Therefore, we designed the present study to evaluate complications and outcomes of patients with traumatic spine in Poursina hospital of Rasht. Mater...

UNLABELLED This review constitutes the first of four reviews that systematically address contemporary knowledge about the mechanical behavior of the cervical vertebrae and the soft-tissues of the cervical spine, under normal conditions and under conditions that result in minor or major injuries. This first review considers the normal kinematics of the cervical spine, which predicates the apprec...

Low back pain is a very common problem and the consequent cost is enormous. In spite of the prevalence, however, it is still difficult to obtain accurate diagnostics. Mechanical disorder is now often regarded as the main cause. Presently, a number of studies are directed at measurement of spine kinematics. Since the lumbar spine is a deep-rooted structure, this has been difficult until digital ...

Bone scintigraphy performed on a patient during the middle of radiation therapy for an inoperable left lung malignancy showed diffusely increased uptake in the thoracic vertebrae and relatively increased uptake in the ribs of the left thorax. This bone scan finding is apparently a transient phenomenon that occurs in response to irradiation and eventually leads to photon deficiency or photopenia...

Spondylolisthesis of the fourth cervical vertebra is reported in a thirty-four-year-old woman. Only one other case at this level has been found in the literature, but others have been recorded of the sixth cervical vertebra.

We report a case of a 67-year-old female with severely destabilized lumbar spine caused by metastatic malignant tumor. The primary lesion was a thyroid follicular adenocarcinoma. Complete destruction of the L3, L4, and L5 vertebrae had resulted in severe instability, which left the patient with severe back pain and bed-ridden. Since the vertebrae were so severely damaged at 3 levels, 4 rods wer...
