闭合性手术治疗膑下脂垫炎疗效分析

膑下脂垫炎,又称膑下脂肪垫劳损是常见病之一。临床常以膝关节炎,膝关节滑膜炎、膑骨软化症等诊断而延误治疗,一般服药和理疗难以奏效。我部对41例膑下脂垫炎、采用闭合性手术治疗,收到满意效果。现报告如下:

Calculation of Measurement Uncertainty for Stiffness Modulus of Asphalt Mixture

Asphalt mixture is a highly heterogeneous material, which is one of the reasons for high measurements uncertainty when subjected to tests. The results of such tests are often unreliable, which may lead to making bad professional judgments. They can be avoided by carrying out reliable analyses of measurement uncertainty adequate for the research methods used and conducted before the actual research is done. This paper presents the calculation of measurements uncertainty using as an example--the determination of the stiffness modulus of the asphalt mixture, which, in turn, was accomplished using the indirect tension method. The paper also shows the employment of the basic methods of statistical analysis, such as testing two mean values and conformity tests. Essential concepts in measurements uncertainty have been compiled and the determination of the stiffness module parameters are discussed. It has been demonstrated that the biggest source of error in the stiffness modulus measuring process is the displacement measure. The aim of the research was to find the measurement uncertainty for stiffness modulus by an indirect tensile test and the presentation of examples of the used statistical methods.

双侧膝关节髌骨不发育一例报告

患者女，62岁。以“双膝关节不适、酸痛两月余”为主诉，来我院就诊。查体：双侧膝关节对称，无畸形、无红肿、活动自如。双膝关节无过伸、无内、外翻及无力现象。股四头肌无萎缩，于双膝关节前未触及髌骨。双膝无压痛点，活动时有轻微摩擦感，无弹响。双膝关节屈伸、旋转功能均正常。重力试验、过伸试验及抽屉试验均阴性。询问病史，双膝关节无外伤、手术史。
