VETERINARY AND COMPARATIVE ORTHOPAEDICS AND TRAUMATOLOGY
The equivalent bending stiffness and bending strength of the stainless stee
l DCP and stainless steel LC-DCP were compared. Three plates. of each size.
were tested destructively in 'four point bending'. All of the LC-DCP were
significantly less stiff and less strong than the comparable size DCP. with
the exception of the 4.5 mm narrow LC-DCP which was significantly stronger
and more stiff than the 4.5 mm narrow DCP (p < .01). The design advantages
of the LC-DCP are ease and versatility of plate application and improved c
ortical blood flow which one assumes promotes fracture healing. Also. the l
ower recorded stiffness of the LC-DCP may be advantageous in that it decrea
ses the stress protection of the plated hone. Since optimal strength and st
iffness of bone plates are currently unknown, the clinical relevance of the
decreased strength and stiffness of the LC-DCP has yet to be determined.
