Traumatic incidents, which can be accounted in daily life, may be occur bone fractures. As well as, controlled surgical implant plantation procedure causes same situation. Long healing time of bone causes serious health and comfort problems. Long healing time increases treatment cost, also causes uncomfortable life event for patient. Further, Serious working ability loss occurred due to mobility losses. If this mobility loss progression has been a matter of health problem in daily life, rehabilitation clinics work load increment has challenged to society. These points show to humanity the condition which is a serious burden to patient and society. Hence, potential treatment method; small magnitude-high frequency vibration affectivity has been studied with engineering discipline perspective. According to this path way, dynamic characteristics of sawbone femur has been studied with using Modal Analysis Technique. Damper coefficient, natural frequency has been obtained with various boundary conditions and their effects on healing process has been demonstrated. With study, also, effect of excitation location on bones dynamic behavior has been questioned

TİTREŞİMİN KEMİK İYİLEŞMESİNE ETKİSİNİN BELİRLENMESİ

Öz

Günümüzde yaşanan birçok travmatik olay kemik hasarlarına neden olmaktadır. Ameliyatlarda İmplant yerleştirilmesi sırasında oluşan kontrollü kemik hasarlarında da benzer durum ile karşılaşılabilmektedir. Her iki durumda kemik rejenerasyonunun uzun olması ciddi konfor ve sağlık problemlerine neden olmaktadır. Uzun iyileşme süreleri tedavi masraflarını arttırmakta, hastanın konforsuz bir süre geçirmesine sebep olmaktadır. Ayrıca mobilitenin büyük oranda azalmasına bağlı olarak ciddi iş kayıpları meydana gelmektedir. Mobilite kaybının ilerlemesi, fizik rehabilitasyon kliniğinin de iş yükünün artmasına sebep olmaktadır. Bu durum ele alındığında görülmektedir ki, kemiklerin iyileşme süreci hem bireye, hem de topluma karşı ekonomik ve sosyal yönden büyük bir yük oluşturmaktadır. Bu nedenle, günümüzde potansiyeli ortaya konan, küçük genlikli-yüksek frekanslı titreşimlerin etkinliği mühendislik disiplini çerçevesinde değerlendirilmiştir. Bu çerçevede sawbone femura ait dinamik karakteristikler modal analiz ile araştırılmıştır. Farklı bağ koşullarındaki frekans ve sönüm karakteristikleri ve bunların kemik iyileşmesine etkileri çalışma neticesinde ortaya konmuştur. Çalışmada ayrıca, farklı titreşim değerlerinde kemiğin mekanik cevabının ne olacağı sorusuna da cevap aranmaktadır.
