Introduction: Cervical rib is relatively uncommon congenital abnormality that originates from the seventh cervical vertebrae and rarely from the sixth vertebrae. The purpose of this paper is to consider that this abnormal condition is an important cause of neurovascular compression at the thoracic outlet. Methods: In this study all patients who were referred to radiology departm...

Between 1970 and 1980, at the National Murayama Hospital, 15 patients with thoracic disc herniation underwent total discectomy by an anterior approach, followed by interbody fusion using autogenous ifiac bone. The results in all 15 patients were favourable. The extrapleural approach to the thoracic vertebrae is preferred because of simplified postoperative care and easier prevention of respirat...

OBJECTIVE To determine the entry for the dorsal pedicular screw in relation to the notch present at the junction of base of the lateral margin of superior articular process with superior border of transverse process in dorsal spine. The advantage of this technique is a constant and easily identifiable entry point which does not involve partial resection of the inferior facet, thus maintaining s...

A 7-month-old Holstein heifer presented with posterior paresis and megaesophagus. At post mortem examination, a nodular tumor was found attached to the thoracic wall and the eighth to eleventh thoracic vertebrae, adjacent to the left posterior pulmonary lobe. The tumor was diagnosed as rhabdomyosarcoma by histology. This is a very rare case of spinal infiltration of rhabdomyosarcoma in cattle.

The house mouse, Mus musculus L., usually has twenty-six presacral vertebrae: these consist of seven cervical, thirteen thoracic and six lumbar vertebrae (Weber, 1950; Deol, 1958; Berry & Searle, 1963; Berry, 1964). The twenty-sixth vertebra is, however, sometimes abnormal, especially among laboratory mice: on one or both sides it may be fused with the sacrum. There are then five typical lumbar...

Cervical spine injuries associated with three-point fixation lap-sash seat belts result from impact against the sash. While such injuries are infrequent and often without serious neurologic sequelae, they may produce serious deficits with grave injuries. Flexion-extension fractures of the lower cervical vertebrae, fractures of the transverse and spinous processes of the lower cervical and upper...

OBJECTIVE To compare the level of agreement of quantitative morphometry of the vertebrae on lateral views of the spine using conventional X-ray and using a dual X-ray absorptiometry device (DXA) in determining the degree of wedging of vertebrae in patients with ankylosing spondylitis (AS). METHODS Thirty patients with AS underwent DXA to acquire single-energy morphometric X-ray absorptiometry...
