Cervifix内固定系统在枕颈融合术中的应用 总被引:14,自引:1,他引:13
目的 介绍Cervifix枕颈内固定系统在枕颈融合术中的应用并评价其疗效。方法 对6例由新鲜创伤和25例由陈旧性创伤、先天畸形、类风湿引起的枕颈失稳病例,采用Cervifix系统进行枕颈融合术;随访手术效果。结果 全部病例得到随访,随访时间9~37个月。3l例均获得骨性融合。内固定无松动,移位和断裂等并发症。脊髓神经功能有不同程度恢复。l例在术中发现有椎动脉损伤,术后无相关症状出现。所有病例未出现与内固定有关的神经脊髓损伤和脑脊液漏等并发症。结论 Cervifix系统固定可靠,器械安装方便,手术操作虽有一定难度,但仍是目前枕颈融合内固定的较好方法: 相似文献

A fundamental prerequisite of population health research is the ability to establish an accurate denominator. This in turn requires that every individual in the study population is counted. However, this seemingly simple principle has become a point of conflict between researchers whose aim is to produce evidence of disparities in population health outcomes and governments whose policies promote (intentionally or not) inequalities that are the underlying causes of health disparities. Research into the health of asylum seekers is a case in point. There is a growing body of evidence documenting the adverse affects of recent changes in asylum-seeking legislation, including mandatory detention. However, much of this evidence has been dismissed by some governments as being unsound, biased and unscientific because, it is argued, evidence is derived from small samples or from case studies. Yet, it is the policies of governments that are the key barrier to the conduct of rigorous population health research on asylum seekers. In this paper, the authors discuss the challenges of counting asylum seekers and the limitations of data reported in some industrialized countries. They argue that the lack of accurate statistical data on asylum seekers has been an effective neo-conservative strategy for erasing the health inequalities in this vulnerable population, indeed a strategy that renders invisible this population. They describe some alternative strategies that may be used by researchers to obtain denominator data on hard-to-reach populations such as asylum seekers. 相似文献

This paper provides new evidence on the degree of income-related inequality in self-assessed health in Belgium. First of all,
we combine the time dimension, which has been shown to be very important in the analysis of inequality, and the use of the
recently developed interval regression approach to transform a categorical health variable in a continuous one. Second, we
measure how the long-run inequality differs from the short-run inequality. Finally, we decompose this health-related income
mobility index as well as the long-run concentration index (CI) itself into its contributors. Using data from the panel survey
of Belgian households (1994–2002), we find that health is pro-rich distributed and that its inequality is underestimated by
9.45% when neglecting the dynamics of individuals over time. Income, education, job status and age are the most important
contributors in the CI and the difference between the short-run and long-run inequality.

Telemetry of programmed and measured data is an important feature of many pacemakers currently used in clinical practice. The ability to receive non-invasive data from the implanted device constitutes a major advantage for the long-term follow-up of the patients and of device performance. There are numerous types of data retrievable via telemetry: parameters of device characteristics (output, battery longevity, impedance, etc), event recorders or counters, event markers, and endocardial electrograms. Ideally, this information should be beneficial in the longitudinal surveilance of modern pacemakers. 相似文献

With the growing number of orthopedic reconstructive spinal procedures, the use of bone grafting has steadily increased in the past decade. An understanding of the biology of bone grafting is essential for both the clinician and radiologist. Despite the advent of computed tomography and magnetic resonance imaging, conventional polydirectional tomography remains an important tool in the evaluation of vertebral body autografts. Trispiral or hypocycloidal tomography plays a valuable role in the assessment of bone graft fusion and possible complications, especially in the presence of metallic fixation devices. We present our imaging experience derived from 375 patients with cervical, thoracic, or lumbar anterior spinal fusion. True graft complications occurred in 27 patients (7%) and consisted of fracture (4%), malpositioning (3%), and infection (<1%). 相似文献

Objective — To study the validity and accuracy of an adjusted questionnaire on medical drug use during pregnancy eight years after the pregnancy. Methods — The ability of a questionnaire on medication during pregnancy to detect actual use (= sensitivity) was tested against information collected 8 years previously (in 1983–1984) from 473 women with high-risk pregnancies who delivered at the University Hospital Nijmegen, the Netherlands. Results — For separate drug groups, the sensitivity varied between 5% and 91%. The timing of use was recalled moderately well. Although specific questions on drug groups did improve the sensitivity as compared to an earlier questionnaire, the improvement was not enough to make the questionnaire valid. High maternal education, low birth weight, low gestational age and a low 5-min Apgar score were related to better recall. The sensitivity of the questionnaire depended on the behavioural score of the child, implying recall bias. Conclusion — Questionnaire data on drug use during pregnancy obtained eight years after delivery are not a valid source of information. 相似文献
