Ex vivo biomechanical evaluation of a bone-screw-fastener for tibial plateau leveling osteotomy.

Introduction: The objective of this study was to investigate the effect of a novel screw type on stiffness and failure characteristics of a tibial plateau leveling osteotomy (TPLO) construct under cyclic loading conditions. The authors hypothesized that bone-screw-fasteners (BSF) would result in superior biomechanical stability compared with locking buttress screws (LBS).

Materials And Methods: Twelve pairs of canine cadaveric pelvic limbs were included in this biomechanical study.
