در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Smith-Petersen vitallium mould arthroplasty: a 45-year follow-up.

THE JOURNAL OF BONE AND JOINT SURGERY tions, including 24-hour ambulant monitoring, revealed only atrial fibrillation. Radiographs of the cervical spine showed spondylolisthesis at the C5 to C6 level. Anterior cervical interbody fusion was performed at this level; the bony changes seen at operation were similar to those described in case 1. He had no more drop attacks during the last year of hi...

Smith-Petersen Vitallium mould arthroplasty: a 62-year follow-up.

A variety of materials were used for early hip prostheses. The introduction of Vitallium by Smith-Petersen represented a further advance in this surgical field. We present the longest known follow-up of a Smith-Petersen Vitallium mould arthroplasty.

Variable scale for measuring from radiographs in Smith-Petersen nailing.

The magnification of the radiographic image, though often of little consequence in nailing the fractured femoral neck, may lead to important errors in nailing the hip to promote arthrodesis. The use of a graduated measure that can be calibrated to the correct scale relieves the surgeon of mental arithmetic. Such a device is shown in Figure 1.
