Abstract :
Objective: The aim of the present study was to determine whether the
side of application of the plate itself affects the mechanical stability of
the fixation. The specific question addressed is whether or not a lateral
or medial plate application is biomechanically better, for the treatment of
distal diaphysis fractures of the femur. Methods: Stability and stiffness of
medial sided plating relative to the conventional lateral sided plating in
distal diaphysis of the femur were measured by analyzing axial loading
forces leading to implant failure. Sixty synthetic femurs were tested
in physiological bending, to calculate the yield and ultimate load to
displacement following fixation of distal diaphysis fractures of the femur
by either medial or lateral sided plating. Axial loading was applied to
samples using a uniaxial testing machine. Results: There was more
implant deformation in the lateral sided plating group – a difference with
statistical significance. Conclusion: Medial sided plating was found to be
as stiff as lateral plating. Medial plating may be a reasonable treatment
option that can be used safely in selected cases. Level of Evidence I,
