Sternotomy closure using rigid plate fixation: a paradigm shift from wire cerclage

Biomechanical Comparison of Wire Circlage and Rigid Plate Fixation for Median Sternotomy Closure in Human Cadaver Specimens

Sternal plating for primary and secondary sternal closure; can it improve sternal stability?

BACKGROUND Sternal instability with mediastinitis is a very serious complication after median sternotomy. Biomechanical studies have suggested superiority of rigid plate fixation over wire cerclage for sternal fixation. This study tests the hypothesis that sternal closure stability can be improved by adding plate fixation in a human cadaver model. METHODS Midline sternotomy was performed in 1...

A Cadaveric, Biomechanical Analysis of Sternal Fixation Systems

Rigid fixation of bony structures has been introduced and implemented as a means to improve stability and reduce motion. Tight fixation has been reported as an essential factor for successful healing1. A variety of devices including plates, intramedullary nails, pedicle screws and interbody fusion devices are used in orthopaedic, spinal and cranial facial procedures to provide rigid fixation. T...

a paradigm shift away from method-wise teaching to strategy-wise teaching: an investigation of reconstructive strategy versus communicative strategy

چکیده: هدف اصلی این مطالعه ی توصیفی تحقیقی در حقیقت تلاشی پساروش-گرا به منظور رسیدن به نتیجه ای منطقی در انتخاب مناسبترین راهکار آموزشی بر گرفته از چارچوب راهبردی مطرح شده توسط والدمر مارتن بوده که به بهترین شکل سازگار و مناسب با سامانه ی آموزشی ایران باشد. از این رو، دو راهکار آموزشی، راهکار ارتباطی و راهکار بازساختی، برای تحقیق و بررسی انتخاب شدند. صریحاً اینکه، در راستای هدف اصلی این پژوهش، ر...
