摘要:

A case of aplastic arch of the atlas (Keller's type) with severe injury to the cervical spine is presented. The impact of the accident was intense enough to produce bony compression of the C7 vertebra, but no injury occurred to the neural elements in the upper cervical spine. The presence of the ligamentous apparatus maintaining the stable movements of the first vertebral connections is of interest. No delay in recovery occurred, and no late complications developed in the seven months following the accident.

摘要:

Two patients with metastatic liposarcoma to the spine developed neurologic deficits that were successfully reversed by laminectomy and partial tumor resections. Recurrences at later dates were treated similarly with comparable outcomes. Paraplegia was forestalled for approximately two years by each of the surgical interventions.

摘要:

Platelet functions were investigated in 16 patients with idiopathic scoliosis (IS), in seven patients with congenital scoliosis (CS), and in 12 healthy individuals who served as a control group. All were females, aged 11 to 22 years. Platelet aggregation anomalies were observed in all IS patients. These constituted an impaired platelet-release reaction when aggregation was induced with ADP or epinephrine, but not with collagen or arachidonic acid. A decreased thromboxane A2synthesis and impaired14C-serotonin release were also observed when platelets were stimulated with ADP or epinephrine. Platelet from CS patients and the controls did not show any functional abnormalities when stimulated with the above four aggregating agents. The platelet function anomaly in IS patients was not associated with prolongation of the bleeding time, spontaneous occurrence of hemorrhagic episodes, or increased bleeding during invasive procedures, including major spinal surgery. The above findings and the recently described platelet structural anomalies in IS may imply that the pathological process operative in idiopathic scoliosis involves not only the axial skeleton, but also cellular blood elements. The similarity between blood platelets and muscle cells, and the anomalies that have been found in both systems in IS, support the notion that a muscle disorder may be involved in the pathogenesis of the disease.

摘要:

Transcutaneous lateral electrical muscle stimulation is demonstrated to be a reasonable alternative to bracing in the treatment of progressive, mild-to-moderate idiopathic scoliosis. Stimulation is applied nightly during sleep, through surface electrodes, on the convex side of the curve, evoking muscle contractions which cause correction of the curvature. Arrest of progression or curve correction in 90 patients treated up to four years (average 15 months) was observed in 84% of 61 patients with single primary curves and 83% of 29 patients with double primary curves. If only the patients who complied totally with the program are considered, the above rates improve to 97% and 93%, respectively. Post-treatment observations of skeletally mature curves for up to two years in 13 patients show no increase in curvature.

摘要:

Twenty patients with radicular compression caused by scoliosis of the lumbar spine with attendant spondyloarthrosis have been relieved of pain with restoration of function following surgical decompression. The stenosis caused by arthropathy is alleviated by foraminotomy and facetectomy after laminectomy over multiple levels along the concavity of the scoliotic curve. The spinous processes and attached ligaments are reconstructed to maintain the normal intermuscular septum contributing to stability. The clinical features are described with documentation by means of radiographic studies, myelography, and CAT scanning in all patients. In addition, the histopathologic findings of the facets removed at the time of surgery are described and the relationship of these findings to the symptomatology is indicated. The long-term results have been gratifying, supporting the efficacy of this means of therapy.

摘要:

The bone mineral areal content and the ultimate compressive strength were determined in 109 lumbar vertebrae from 36 subjects. The bone mineral areal content was related to the number, shape, and localization of the Schmorl's nodes detected in the x-rayed and sectioned vertebral bodies. One type of node, irregular in shape and localization, occurred only in the vertebrae with low bone mineral areal content values and thus in vertebrae with relatively low compressive strength. A second type of Schmorl's nodes, regular in shape and localization, did not reflect any general weakness of the vertebral bodies.

摘要:

The relationship of low-back pain (LBP) to work history and work environment factors was studied in a randomized sample of 940 men from 40 to 47 years of age. The life-time incidence of LBP was 61% the prevalance 31%. In a univariate analysis ten of the variables studied were found to be correlated to the occurrence of LBP: less overtime work, diminished work satisfaction, decreased potential to influence the work situation, lesser demand on concentration, monotonous work, physically heavy work, a high degree of lifting, to a lesser degree sitting, and to a greater standing and walking work posture. When a covariance analysis was applied to these variables, only three had a direct association to LBP. They were less overtime work, monotonous work, and a high degree of lifting.

摘要:

The relationship of low-back pain (LBP) to other diseases and to cardiovascular risk factors was studied in a random sample of 940 men from 40 to 47 years of age. The life-time incidence of LBP was 61%, the prevalence 31%. The prevalence of other diseases was the same as in previous studies in the same region. In a univariate analysis nine variables were found to be correlated to LBP; angina pectoris, calf pain, breathlessness on exertion, smoking, physical activity at work and during leisure time, worry and tension, fatigue at the end of the workday, and perception of stress. When the influence of other variables was assessed by analysis of covariance, four of the variables maintained a direct association with LBP, viz, calf pain on exertion, smoking, a high physical activity at work, and a frequent feeling of worry and tension.

摘要:

The lumbar intervertebral discs are innervated posteriorly by the sinuvertebral nerves, but laterally by branches of the ventral rami and grey rami communicantes. The posterior longitudinal ligament is innervated by the sinuvertebral nerves and the anterior longitudinal ligament by branches of the grey rami. Lateral and intermediate branches of the lumbar dorsal rami supply the iliocostalis lumborum and longissimus thoracis, respectively. Medial branches supply the multifidus, intertransversarii mediales, interspinales, interspinous ligament, and the lumbar zygapophysial joints. The distribution of the intrinsic nerves of the lumbar vertebral column systematically identifies those structures that are potential sources of primary low-back pain.

摘要:

Sixteen cases of lumbar nerve root anomalies found at surgery are reviewed and a classification system presented. All but two patients had an associated disc herniation which initiated the symptomalogy and was the indication for surgery. Fifty percent were found at repeat exploration. Eleven patients had conjoined nerve roots, five had two roots in one foramen, and three had connecting roots. Nerve root anomalies should be suspected in cases of failed disc surgery. Adequate decompression by foraminotomy or excision of pedicles is required as well as discectomy to alleviate the symptomatology.
