摘要:

Three patients with adenocarcinoma of the prostate and metastasis to the cervical spine required stabilization to prevent neurologic impairment. In each instance, a Halo cast was used. This method of stabilization is easily applied and well suited for patients with shortened life expectancy. It allows protection of the cord while chemotherapy and radiation are administered.

摘要:

In nine patients who underwent anterior cervical fusions for cervical spondylosis, preoperative cervical spine films were compared with radiographs taken seven to 15 years after fusion. Eight of the nine patients were found to have radiographic evidence of increased degenerative diseases located primarily below the level of fusion but occasionally occurring both above and below the fusion. Whether these degenerative changes are the body's response to altered mechanical forces on joints next to a now immobile spinal segment or whether these changes merely represent the natural progression of the degenerative disease process could not be ascertained from this study. Perhaps both factors contributed.

摘要:

The equations of equilibrium are set up for the thoracic and lumbar spine and involve body weight, external load, muscle forces, and intervertebral reactions. These equations are solved using a linear programming technique that minimizes the total force in the system. The solution gives numeric values for the muscle forces and intervertebral reactions. The results for a subject in progressive forward flexion and in lateral bend are presented. Also examined are the effects of three different orthotic devices on the muscle forces of a patient with a scoliotic spine.

摘要:

A variety of techniques were used to study the morbid anatomy of 19 spines demonstrating degenerative spondylolisthesis in order to define the precise changes which produce this lesion and its radiographic appearance. An association between this affliction and vascular disease is suggested. The studies indicate that the listhesis is basically a persistent rotary deformity and not a simple forward displacement. Furthermore, there is no construction of the neural canal at the site of the listhesis. These findings suggest that the myelographic defect and symptomatology arise from traction applied to the nerve root by the medially displaced pedicle.

摘要:

The records of 3920 patients (2068 females, 1852 males) entering a model family practice unit between 1975 and 1978 have been analyzed. Eleven percent of males and 9.5% of females reported an episode of low-back pain during that 3-year interval. The complaint of medically reported low-back pain was significantly related to occupational factors such as truck driving (P<0.001), lifting, carrying, pulling, pushing, and twisting (P<0.001 for all variables) as well as nondriving vibrational exposure (P<0.001). Patients reporting low-back pain also reported more episodes of anxiety (P<0.001) and depression (P<0.001) and had more emotionally stressful occupations (P<0.001). The mean number of pregnancies was greater in women with low-back pain (2.6) than in those without (1.6) (P<0.001). The low-back pain sufferers were more likely to be cigarette smokers (P<0.001), particularly when smoking was accompanied by a chronic cough (P<0.001). This population is currently under prospective study to define the relevance of each of these risk factors to the complaint of low-back pain.

摘要:

Epidural venography is a relatively simple, safe and highly accurate method of diagnosing lumbar disc herniations.1,3,4,6,7,12Good opacification of the epidural venous plexus can be obtained by selective catheterization of the ascending lumbar vein or pre-sacral branches of the internal iliac veins.8Experience with 100 cases of lumbar disc herniations is described. The authors think that epidural venography is a more sensitive technique than myelography, particularly with lateral disc herniation at the L5-S1 level. It is not associated with the morbidity or complications of myelography and can be performed as an outpatient procedure. Epidural venography is recommended as the examination of choice in patients with suspected lumbar disc herniation.

摘要:

Thirty-eight patients with the diagnosis of postoperative epiduro-arachnoiditis are reported upon. All had had previous surgery for disc herniation, and the diagnosis of epiduro-arachnoiditis was confirmed at repeat surgery. Massive epidural scarring with no coexistent pathologic condition was found in every patient, and adhesive arachnoiditis was noted in three. The common clinical presentation consisted of low-back pain and sciatica, and radicular pain was usually a continuation or a recurrence of the preoperative sciatic pain. Neurologic deficits were mild, and no patients with the classic picture of adhesive arachnoiditis were found. Myelographic patterns did not disclose any correlation with the clinical symptoms. Five myelograms were normal, while six others simulated a recurrent disc herniation. The results of scar excision were good in 13 patients, fair in eight, and a failure in 17.

摘要:

The cause of spondylolysis and spondylolisthesis remains unknown. There is increasing evidence that the defect in the pars interarticularis is due to fatigue fracture rather than being of congenital origin. We describe the youngest patient on record with spondylolysis and spondylolisthesis in whom roentgenograms that showed no abnormality had previously been taken. This case supports the hypothesis that spondylolysis and spondylolisthesis are acquired and not congenital, even when discovered in a very young child.

摘要:

Seventy cases of surgically documented herniated lumbar disc in children and adolescents were analyzed. Twenty-six of the 70 cases were followed at least five years postoperatively. The incidence of juvenile disc herniation in Japanese patients appears to be much higher than in Caucasians. Repeated trauma may be an important etiological factor of herniated lumbar disc in this age group. The history and physical findings in children and adolescents are not fundamentally different from those in the adult, although abnormal neurological findings are not common. Fiveyear follow-up studies suggest that interlaminal laminectomy without fusion is the best procedure when surgical treatment of herniated lumbar disc is necessary in children and adolescents.

摘要:

Ninety-seven patients who underwent anterior interbody fusion for lumbar disc derangement were examined two to 15 years after the operation. Complete relief of back pain was obtained in 60% and of sciatica in 85%; marked improvement of back pain was obtained in 29% and of sciatica in 10%. The fusion rate was 63% and was only slightly correlated with symptomatic improvement. Many complications were encountered, most of which were transient.
