תערוכת פרויקטי גמר 2013 1
•The project “A finite element model of friction
between K wire and bone” engages in
mechanics of physiological systems particularly
in the analysis of friction between the bone and
the K wire.
•K wire is placed in the bone due to
Supracondylar fractures in children.
•A K wire (Kirschner wire) is a stainless steel
pin. These metallic pins or wires are used to
hold bone fragments together or to provide an
anchor for skeletal traction.

Background
The problem
Every surgeon uses the technique he is most comfortable with.
The gripping model between The K wires and the bone is not clear.
3 different K wire fixation methods
Objectives
•To construct a simplified finite element model of a KW inserted into a
bony environment which will include a realistic friction model
•To validate predicted values with existing experimental values
•To conduct result analysis
