Abstract

In the development of new
strategies for fracture fixation, new methods have to be tested biomechanically
under in vitro conditions before clinical trials can be performed. Several
recent developments, including tensile, compressive, and bending tests fresh
whole bone specimens, offer the possibility to understand animal bones
mechanical behavior. Therefore, the aims of the present study were to determine
the effects of three point bending tests on the lamb metacarpal bones at
different speeds and determine the mechanical properties of bone and to compare
these properties with the finite element analysis of the tests. 12 specimens
were obtained from 1 year old Ankara curly lambs. Three point bending tests
were conducted using three different compression speeds to assess and compare
bone fracture properties. From the test results bending moments, stresses,
strains and deformations were calculated for three different compression
speeds. Finite Element Analysis results were compared to the test results.
Because of the use fresh bone specimens of an animal part are used like in vivo
tests in biomechanical studies, investigating failure loads of the metacarpus
by bending tests and numerical analysis are guiding for clinical operations and
computer simulations.
