摘要:

A 21-year-old male with a complete paraplegia secondary to a .38 caliber, self-inflicted gunshot wound underwent a myelorrhaphy 15 months following injury. The patient expired 14 months later without realizing neurologic improvement.

摘要:

The histopathologic findings in a human spinal cord in which there was an attempt at myelorrhaphy are presented. There was no evidence of regeneration of long tract fibers across or in the vicinity of the myelorrhaphy

摘要:

Paravertebral infection occurred following 3 of the first 100 Dwyer spinal instrumentations performed in Hong Kong. The implant had to be removed in every case to eradicate the infection. Further deformity occurred with the exception of 1 patient who underwent posterior spinal fusion and Harrington rod instrumentation.

摘要:

Twenty patients underwent bilateral-lateral column fusion for symptomatic spondylolisthesis which had failed to respond to conservative measures. The average age was 14.5 years and the followup has been 4.3 years. The majority were Grade III or IV. All developed a solid roentgenographic appearance of the fusion within the first year. Nineteen of the 20 obtained good-to-excellent results and have returned to full unrestricted activity. Forty percent of the surgically treated patients had congenital lumbosacral subluxation (Newman Type I) versus 12% of the nonoperative group. In addition, children with Grades III and IV spondylolisthesis were likely to require surgery.

摘要:

The fallacies of the term stenosis are discussed. Propositions for a more precise definition of the stenotic conditions are given, based on the distinction between transport stenosis and compressive stenosis and their different properties. Uncertainties in the present nomenclature of the various forms of stenosis of the lumbar vertebral canal are discussed. Measuring the diameters of the lumbar vertebral canal, not only in roentgenograms but also during surgery, is an important aid to more precision in nomenclature.

摘要:

Studies of the form and function of the ligamentum flavum have been made directly, by investigating the structure and indirectly, by appraising properties of analogous elastic tissue structures. The flavum is noted to retain its elastic content with age and to demonstrate shortening and thickening as a result of its elasticity when its insertion is incised. True thickening of the intact ligament was not encountered in 107 surgical dissections. The ligamentum flavum is proposed to play only a passive role in neural entrapment problems. Based on studies described, a surgical procedure is proposed in which the ligamentum flavum is retained to protect against adhesions.

摘要:

Six cases are presented of patients who have had surgical procedures for cervical or lumbar disc protrusions or spondylosis. Myelograms of these patients are shown to demonstrate that, following removal of a compressive spinal lesion, the myelogram may improve or become normal. This is potentially important in the evaluation of the postoperative patient who develops persistence or recurrence of symptoms since the myelogram may indicate a specific lesion amenable to surgical relief rather than the poorly defined “postoperative changes.”

摘要:

A method for determining the permeability of the rabbit intervertebral disc to fluorescein and formation of a suitable index are presented. A significant decrease in the index with aging was found in both sexes; however, male discs were significantly less permeable than female discs in all ages tested. The decrease in permeability of the disc matrix is thought to be important with respect to the onset of disc degeneration.
