A Biomechanical Comparison of a Novel Expandable Photodynamic
Intramedullary System to a Metal Plate and Screw System in Humerus
and Femur Osteotomy Models
The biomechanical performance of a locking compression
plate system was compared to an intramedullary photodynamic
bone stabilization system in a femur and humerus osteotomy model.
The photodynamic bone stabilization system utilizes.
This system has been in clinical use since 2010.
Synthetic bones engineered to mimic the
biomechanical properties of natural bone were cut to
photodynamic bone stabilization system.
biomechanical parameters measured, the 17 mm intramedullary
photodynamic bone stabilization system exceeded the mechanical
strength and durability of the locking compression
plate system in the femur osteotomy model.
It was found that in all biomechanical parameters measured,
the 15 mm intramedullary photodynamic bone stabilization
system performed equivalently or exceeded the mechanical
strength and durability of the
locking compression plate system.
This testing combined with long-term clinical use, and in
vivo data from a large animal model, suggest that femur fixation
by an intramedullary photodynamic bone stabilization system will
provide equivalent biomechanical properties to a locking
compression plate once implanted.
Internal plate fixation and intramedullary nailing are long-standing methods to provide
fixation of fractures of the femoral and humeral shaft.
Internal fixation needs to provide enough rigidity, compression, and have adequate durability
to promote bone healing.
