Mechanical Evaluation Of Aluminum Oxide Roughened Screws In Equine Third Metacarpal Bone, Petrisor Baia
LSU Master's Theses
ABSTRACT Objectives – To compare the osseointegration of roughened and electropolished 5.5 mm cortical screws used to secure a 4.5 mm broad dynamic compression plate (DCP) in equine third metacarpal (MC3) bones. Study Design – In vivo study Animals – 5 Adult thoroughbred horses (2-7 years old). Methods – For each horse one MC3 was randomly assigned to secure a 4.5 mm broad DCP with 4aluminum oxide (Al2O3) roughened screws on the dorsal mid diaphysis. Four regular electropolished screws used to secure a similar plate on the contralateral limb served as control. They were removed at 12 weeks and the …
