摘要:

Tomography was performed on 136 patients following trauma to the cervical spine. In approximately 25% of the patients tomograms demonstrated abnormalities not identified on the plain cervical spine radiographs: eg, odontoid fractures, facet fractures and dislocations, congenital lesions, multiple fractures, and other unsuspected lesions. In an additional 25% of patients, the tomograms disproved the suspected plain film findings. In 12.5% of the cases examined, the tomographic examination dramatically altered the management of the patient. In an additional 25%, the patient's management was significantly modified by the information obtained at tomography.

摘要:

A technique of Pantopaque myelography in patients with acute cervical spinal injuries is described. The technique is simple and involves performing the myelogram with the patient in traction on a Stryker Frame. Fast and accurate results are obtained with minimal discomfort to the patient and without the risk of undue manipulation of the cervical spine.

摘要:

The etiology of idiopathic scoliosis is still unsolved, despite extensive research. This paper analyzes the different factors of relevance. Recent investigations have convincingly demonstrated the hereditary traits of idiopathic scoliosis. In the adolescent group a specific growth pattern has also been demonstrated, while muscular factors and biochemical changes of connective tissues are somewhat more uncertain. A significant number of patients demonstrate asymmetries in the vestibular apparatus and electroencephalographic abnormalities. Because of the essential role of the vestibular and central nervous systems in the postural equilibrium, functional asymmetries or minor pathologic changes in these structures might also be factors of importance. It is our view that adolescent idiopathic scoliosis should be regarded as a multifactorial disease. Combining the findings in recent investigations, a possible model for the pathogenesis of the disease is outlined.

摘要:

Thirty patients having T1 through T11 fractures stabilized by fusion or Harrington instrumentation were followed from 1964 through 1975. They were studied to determine the results in achieving spine stabilization in injury treatment early as well as late; the neurologic course before and after treatment; and the effect of treatment on the course of the spine deformity and the neurologic deficit. The findings support the following conclusions: unstable thoracic spine fractures may be managed successfully by Harrington instrumentation and spine fusion; stable fractures may be made unstable by laminectomy; complete paraplegia is unaltered by type of treatment; incomplete cord lesions carry a favorable prognosis; adequate decompression may be furnished by fracture alignment.

摘要:

A pathologic compression fracture of T11 caused paraparesis and disturbed vesical and anorectal function in a 33-year-old woman. Laminectomy was performed and the lesion proved to be a benign giant-cell tumor. The whole affected vertebra was removed and the spine was reconstructed by inserting iliac bone autografts between T10 and T12. After incorporation of the grafts the patient regained very good function.

摘要:

The forces acting across the pars interarticularis of the fifth lumbar vertebra while in the fully flexed and partially flexed postures are calculated. These values are compared with the strength of the neural arch obtained experimentally. This comparison shows the neural arch to be a relatively strong structure. However, results are presented which indicate that a spondylolytic type fracture can be initiated by fatigue loading. The mechanics of spondylolysis and spondylolisthesis are shown to be related through the shearing properties of the intervertebral disc.

摘要:

Responses to the graduated spinal block test and Minnesota Multiphasic Personality Inventory (MMPI) were examined in 55 patients with chronic low-back pain. The two tests agreed only 54.5% of the time in classifying patients as having either functional or organic origins of pain. Patients diagnosed as functional on the spinal block test had significantly higher scores on MMPI scales measuring hypochondriasis and repression, but otherwise were strikingly similar to patients diagnosed as organic by this procedure. The study does not strongly support the use of the graduated spinal block test as a diagnostic aid in recognizing the emotional component of chronic back pain. In a second part of the study, an 18-month followup of 38 patients indicated that the graduated spinal block test was predictive of patients' eventual return to work, while MMPI scales reflecting passivity and the use of repression were strongly related to subsequent functional activity level and perceived pain.

摘要:

A technique is described for performing lumbar myelography that provides for patient comfort while decreasing patient risk and increasing accuracy of interpretation. A study of 205 myelograms performed at the University of Miami School of Medicine as well as a literature review made it apparent that meticulous attention to technique could decrease the complication rate of myelography and increase diagnostic acumen.

摘要:

The authors participated in a double blind study on the effectiveness of chymopapain in the treatment of intervertebral disc disease. Results of the double blind study indicated that chymopapain was no more effective than a placebo. The authors challenge the validity of the double blind study because of timing of result evaluation, possible therapeutic activities of the placebo utilized, and possible insufficient dose of chymopapain.
