Biomechanical evaluation of strength and stiffness of 2.0 mm and 1.5 mm locking plates with various screw configurations on rabbit tibias.

Objective: The objective of this study was to compare the strength and stiffness of 1.5 mm and 2.0 mm locking plates with various screw fixation configurations applied to the tibia bones of rabbits.

Biomechanical analysis of 3 fixation techniques in rabbit radius and humerus bones.

The objective of this study was to compare the strength and stiffness of various fixation methods applied to the long bones of the rabbit forelimb. Twenty rabbit radius/ulna and 20 rabbit humeri were randomly assigned to 1 of 4 groups. Control bones remained intact, whereas all others were osteotomized to create fracture models that were fixated with locking plate and locking screws (LP), veterinary cuttable plate (VCP) with cortical screws, or external skeletal fixator constructs (ESF), and tested in 4-point bending until failure.
