BackgroundWidely used rod rotation and translation techniques for idiopathic scoliosis (IS) are effective in correcting spinal coronal deformity. Bilateral apical vertebral derotation technique by vertebral column manipulation (VCM) and vertebral coplanar alignment (VCA) technique are two strategies for three-dimensional (3D) correction for IS. The purpose of this study is to compare the post-surgical results and technical features of the bilateral apical vertebral derotation technique by VCM against the VCA technique in patients with Lenke type 1 IS.MethodsForty-eight patients with Lenke type 1 IS were enrolled in the present prospective clinical assay. They were divided into groups A (bilateral apical vertebral derotation technique by VCM, n=24) and B (VCA technique, n=24). Radiographic parameters measured before and after surgery included the Cobb angle, thoracic kyphosis, and apical vertebral rotation. Scoliosis Research Society (SRS)-22 scores were evaluated during the final follow-up. The differences in the demographics, surgical details, and radiographic measurements between the two groups were determined using a T test. The Mann–Whitney U test was used to evaluate the differences in the SRS-22 scores. A value of P<0.05 was considered statistically significant.ResultsIn the coronal plane, a significant difference was found in the correction rate of the major curve (group A: 84.8%, group B: 78.4%; P=0.045) and in the Cincinnati Correction Index between two groups (group A: 2.21, group B: 1.98; P=0.047). In the sagittal plane, no difference was found in the postoperative thoracic kyphosis between the two groups (P=0.328). In the transverse plane, no difference was found between the two groups in the correction rates of the rotation angle sagittal (P=0.298), rib hump (P=0.934), apical vertebral body-to-rib ratio (P=0.988), or apical rib spread difference (P=0.184). Patients underwent follow up for an average of 21.9 and 22.2 months in groups A and B, respectively. Results obtained at the final follow-up indicated no significant loss of correction. No differences were found in the SRS-22 scores between the two groups. No aortic or neurological complications were observed.ConclusionsThe 3D deformity of the spine was effectively corrected using the bilateral apical vertebral derotation technique by VCM and the VCA technique, and encouraging post-surgical results were obtained for patients with Lenke type 1 IS. The two techniques were effective in allowing 3D correctional force that was applied in different ways.
Recurrence of spinal tuberculosis, incorrect choice of internal fixation strategy, unsuitable fused segments, and poor achievement of sagittal and coronal balance after surgery may lead to secondary deformity postoperatively. Good clinical outcomes were obtained by revision surgery to extend the fused segments, albeit with decreased spinal range of motion.
With the rapid development of tourism industry in China, each scenic spot of Beijing by virtue of its cultural heritage and natural advantage to seize the market. Tourist information center, as a special and important tourist attractions in the area, at the same time, it is the tourist attractions' image, higher requirements are asked to the design. With the improvement on people's quality of life and the progress of the times, an increasing number of people is pursuing a kind of spiritual tourism experience, and they pay more attention to the quality of tourism. Therefore the traditional design of tourist information center has been unable to more appropriate modern tourism demand. This article about the view of landscape design of the tourist information center in Beijing.
Brand visual image plays a very important role in modern tourism marketing, and it is an important channel for tourists to obtain tourism destination positioning. It can not only provide consumers with directional information of tourism destination, but also help the development of local industry and the sale of products. Based on the analysis of the role of visual image design in the shaping of rural tourism brand image, combined with the background of Rural Revitalization policy and the characteristics of rural tourism brand image, this paper constructs the model of rural tourism brand image, and puts forward the promotion strategy of rural tourism brand image.
