Kyphosis  英 /kaɪ'fəʊsɪs/  美 /kaɪ'fosɪs/     

释义   n. [外科] 驼背

例句   Theoretically, segmental fixation provides for additional fixation points that may in fracture reduction and kyphosis correction. 理论上来说,节段性固定提供了附加的固定点,可能有利于骨折还原及驼背矫正。


概述

脊柱后凸是脊柱畸形中最为常见的一种症状,正常脊柱存在生理性的弯曲,形成的后凸角度较小,一般不超过50°,但在病理性脊柱后凸患者中这一角度则要>60°,且呈不断增加的趋势。 病因学非固定性畸形可在医生的被动活动或病人的主动活动时被矫正,包括姿势性驼背和代偿性脊柱后凸。固定性畸形多由其他疾病所导致,其中又分为脊柱弓状后凸(包括先天性脊柱后凸、瘫痪性脊柱后凸、年龄相关性驼背、佝偻病性驼背、强直性脊柱炎、多发性骨骺发育异常、原发性骨质疏松症、次发性骨骺骨软骨病、氟骨症和甲状旁腺功能亢进骨营养不良等,

Chronic obstructive pulmonary disease (COPD) is caused by significant exposure to noxious particles and gases, most often tobacco smoking but also exposure to air pollution. It is characterized by chronic airflow limitation that is caused by a mixture of small airways disease (e.g. obstructive bronchiolitis) and parenchymal destruction (emphysema). Although COPD is primarily a pulmonary disease, there are significant comorbidities and extrapulmonary effects, such as cardiovascular disease, diabetes, muscle wasting, and osteoporosis. The reported prevalence of vertebral fractures (VFs) is high among patients with COPD (9-79%) and we have recently shown that incident VF risk is high in COPD patients and (former) smokers without COPD with one or more prevalent VFs. Hyperkyphosis, an excessive increase in thoracic spinal curvature, is a common condition estimated to affect about 20-40% of the older population. However, since normal kyphosis is increasing with age, cutoff values defining hyperkyphosis are lacking. Although presence of VFs is often reported to be the main cause of increased kyphosis, more than half of the hyperkyphotic patients do not have VFs. Other possible causes can be Scheuermann’s disease, intervertebral disk degeneration, and muscle weakness.

1280/5000慢性阻塞性肺疾病(COPD)是由大量接触有害颗粒和气体(最常见的是吸烟)以及空气污染引起的。它的特征是慢性气流受限,是由小气道疾病(例如阻塞性细支气管炎)和实质破坏(肺气肿)的混合物引起的。尽管COPD主要是肺部疾病,但仍存在明显的合并症和肺外影响,例如心血管疾病,糖尿病,肌肉萎缩和骨质疏松。据报道,患有COPD的患者椎骨骨折(VFs)的患病率很高(9-79%),我们最近发现,患有COPD的COPD患者和(以前的)吸烟者中有一个或多个流行VF的吸烟者发生VF的风险很高。驼背过度症是胸椎曲率的过度增加,是一种常见病,估计会影响约20-40%的老年人口。然而,由于正常的后凸畸形随着年龄增长而增加,因此缺乏定义过度后凸畸形的临界值。尽管经常报告存在VFs是导致后凸畸形增加的主要原因,但一半以上的高后凸患者没有VFs。其他可能的原因可能是Scheuermann病,椎间盘退变和肌肉无力。
