BackgroundAnterior and posterior pelvic tilt appears to play a role in total hip arthroplasty (THA) stability. When changing from the standing to the sitting position, the pelvis typically rotates posteriorly while the hips flex and this affects the femoro-acetabular positions. This case-control study compares changes in 3-D acetabular cup orientation during functional pelvic tilt between posterior THA dislocations vs stable THAs.MethodsStanding and sitting 3-D cup orientation was compared between fifteen posterior dislocations vs 233 prospectively followed stable THAs. 3-D cup orientation was calculated using previously validated trigonometric algorithms on biplanar radiographs. Those algorithms combine the angles in the three anatomical planes (coronal inclination, transverse version, and sagittal ante-inclination) in the standing position with the change in sagittal pelvic tilt from standing to sitting to calculate the 3-D orientation in the sitting position.ResultsThe standing cup orientation of the dislocated THAs was only characterized by a lower coronal inclination (P = .039). Compared with the controls, from standing to sitting, they showed less posterior pelvic tilt (P < .001). This led to a significant lower coronal inclination (P < .001) and sagittal ante-inclination (P < .001) in the sitting position but similar transverse version (P = .366).ConclusionsComparing posterior THA dislocations to stable THAs, there is a lower increase of all three orientation angles from standing to sitting. This leads to a decreased sitting coronal inclination and sagittal ante-inclination which may lead to an increased risk of impingement ensued by THA instability. By contrast, the transverse version was not significantly different in both positions. This confirms the importance of biplanar data on functional cup orientation.Level of EvidenceDiagnostic, Level III.  相似文献

Social insurance administrative officers’ decision-making skills influence their efficiency at work and their general well-being. At work their tasks are characterised by complexity and a need for order and accountability. Moreover, cases should usually be handled and finalised within the imposed time frames. We investigated skills related to decision-making success among social insurance officers. In total, 118 administrative officers at the Swedish Social Insurance Agency (66% response rate) responded to questions on scales and measures relating to cognitive-rational, socio-emotional and time approach features of decision-making skill. In addition, they responded to questions on three scales pertaining to outcomes of everyday decisions in terms of subjective everyday difficulties, tendencies to burnout and depressive symptoms. The results showed that cognitive-rational competence was associated with lower reports of subjective everyday difficulties and depressive symptoms and thereby contributed to the explained variance in decision outcomes. Furthermore, socio-emotional and time approach features of decision-making skills contributed to the explanation for subjective everyday difficulties, tendencies to burnout and depressive symptoms. The results corroborate the basic assumption and usefulness of a broad approach in the definition and assessment of decision-making skills in human service professions in general, and of administrative officers in social insurance agencies in particular. Recommendations for future research and the implications of the results are discussed.  相似文献

目的 了解豫南农村地区青少年校园暴力状况及性取向对其的影响,为豫南农村地区青少年校园暴力和身心健康干预提供借鉴。方法 采用分层整群抽样的方法2019年在豫南农村地区对4214名青少年进行问卷调查。结果 豫南农村地区青少年遭受校园暴力的比例为50.65%。在不同年级、性别、父亲学历、母亲学历、学习成绩、性取向方面学生遭受校园暴力的比例相比较,差异均有统计学意义(〖XC小五号.EPS;P〗值分别为21.56、101.65、8.78、9.34、11.94、18.54,P<0.01)。多因素logistic回归分析表明,同性恋(OR值为1.52,95%CI为1.01~2.28)、双性恋(OR值为1.69,95%CI为1.27~2.22)与青少年遭受校园暴力呈现正相关关系(P<0.05或0.01)。结论 豫南农村地区青少年校园暴力状况不容乐观,应采取有效干预措施进行暴力行为的干预和引导,同时教导青少年理性面对同性恋或双性恋群体,减少或避免校园暴力的发生。  相似文献

本文通过测量具有不同流变特性的红细胞悬浮液电阻抗的动态与静态变化,研究了红细胞聚集与取向对其悬浮液电阻抗的影响。首次得出以下结论:1.红细胞聚集使其悬浮液电阻抗显著减小。2.由于低切变率下红细胞聚集与高切变率下红细胞取向的共同影响,使血液电阻抗随切变率的变化具有双相特性。这增加了对血液电特性的新认识,表明可利用电阻抗测定红细胞聚性。  相似文献

目的 探讨基于加速康复外科(ERAS)理念的健康行动过程取向(HAPA)模型健康教育在肝切除术中的应用效果。方法 选取2020年1月至2022年6月在湖北省荆州市第一人民医院行肝切除术的患者90例,按照随机数字表法,分为干预组和对照组,每组45例。对照组给予常规健康教育,干预组给予基于ERAS理念的HAPA模型健康教育,比较两组患者术后身体体征恢复情况、自我效能感、健康行为、自我管理能力差异。结果 干预组患者首次活动时间为(23.87±4.32)min、首次进食时间为(9.87±2.67)h、首次通气时间为(45.28±4.32)min、引流管拔管时间为(22.45±4.25)h、住院时间为(10.53±2.85)d,均短于对照组,差异均有统计学意义(P<0.05);干预后,干预组患者自我效能感量表、健康促进生活方式量表Ⅱ、成年人健康自我管理能力测评量表评分均高于对照组,且干预前后各指标差值比较,差异均有统计学意义(P<0.05)。结论 肝切除术患者采用基于ERAS理念的HAPA模型健康教育干预,能够提高术后身体体征恢复效率,改善患者自我效能感、健康行为及自我管理能力。  相似文献

Many researchers interested in sexual orientation can be separated into two camps: The lumpers, who try to reduce sexual classifications to as small a number of categories as possible, and the splitters, who try to show differences among groups and individuals that make classification schemes increasingly difficult and/or intricate. We report factor analyses of the Klein Grid (a questionnaire with 21 sexual orientation items) to see how many factors emerge in two samples of strikingly different origins. In both samples, the first factor to emerge loaded substantially on all of the Klein Grid's 21 items. This factor accounted for a majority of the variance. In both samples, a second, correlated factor emerged which indexed a separation between most of the items and those having to do with social and/or emotional preferences. In both samples, a third correlated factor also emerged, but this factor differed between the two populations: one refined the social/emotional distinction and the other distinguished ideal behavior from past and current behavior. We conclude on the basis of our analysis that both the lumpers and the splitters are correct.Supported by NIMH grants IP50 MH 45294 and R01 MH 43298.  相似文献

In osteoarthritis of the knee, degenerative changes occur in the articular cartilage and underlying subchondral bone, particularly of the medial tibial condyle. Cancellous bone sclerosis that accompanies osteoarthritis is not only the result of an increase in bone volume fraction but also a change in trabecular structure. In a comparison with agematched controls (n=4), osteoarthritis (n=11) demonstrated a significant (P0.05) increase in bone volume fraction and trabecular thickness. Overal trabecular orientation in the osteoarthritic group was more vertical or perpendicular to the articular surface than the control group (P0.05) especially in the trabeculae of the cancellous bone layer closest to the articular surface. These alterations in trabecular bone structure could have significant consequences for the mechanical properties of osteoarthritic bone.  相似文献
