Methods: Seventy-eight patients with thoracolumbar burst fractures were retrospectively reviewed to calculate the stenotic ratio of spinal canal based on the midsagittal diameters and the hyphosis angle according to Cobb. The ASIA scoring of motor function of lower extremities was recorded . Results: The differences (P > 0.05) of the stenotic ratio of spinal canal and the kyphosis angle were not significant between patients without neurological deficit, with incomplete and complete lesions. No significant correlation(P > 0.05) between the stenotic ratio of spinal canal and the kyphosis angle, and ASIA scoring was noted. Conclusion:The severity of spinal cord injuries in thoracolumbar burst fractures is not predicted according to the percentage of canal stenosis or the degree of kyphesis induced by thoracolumbar burst fractures.展开更多

It can cause a terrible pain. The author has treated 66 cases by massotherapy, who were confirmatively diagnosed as having protrusion of the lumbar intervertebral disc by X-ray film and computer-aided tomography, with satisfactory results as reported in the following.Clinical DataAmong the 66 cases in this series, 49 were male and 17 female, ranging in age from 26 to 59 years, averaging 36.2 years. All the patients had got lumbago and unilateral ischialgia, with the left side affected in 37 cases and the right side in 29 cases. The leg pain radiating to lateral malleolus was found in 28 cases, to dorsum of the foot in 24 cases, and to the toes in 14 cases. Intermittent claudication was present in 22 cases, numbness of the affected foot in 16 cases, pain exacerbated when coughing in 35 cases, scoliosis in 21 cases, and positive Lasegue's sign in 48 cases.展开更多

The results showed that the cure rate in the treatment group was 83.9%, and that in the control group was 57.1%, with a statistically significant difference between the two groups (P<0.01), indicating that the former is a more effective therapy for protrusion of the lumbar intervertebral disc.展开更多

To measure the shift-amount at each angular position that was required for reconstruction of panoramic x-ray images of the dental arch, strip images of a calibration phantom were acquired. Then, a shift-amount table was prepared from these images, and the other shift-amount table, which was used to reconstruct a panoramic image of the cervical vertebrae, was prepared by inverting the curve of the shift-amount table upside down. Using these two tables, images focused on the dental arch and cervical vertebrae of a patient were made with the original strip data of the patient. The shadow of the cervical vertebrae appearing on the image focused on the dental arch was removed using the two above-mentioned images and blurring functions defined at two focusing geometries. The validity of the proposed method was evaluated with clinically acquired data of two patients. The shadow of the cervical vertebrae was successfully eliminated, and the contrast of the front teeth and detailed structures of the jaw bones was improved. The results of the experiments showed that our proposed method was significantly effective in removing the shadow of the cervical vertebrae from conventional panoramic x-ray images.展开更多
