Abstract

Background: This investigation compares the biomechanical properties of one-third tubular and newer anatomically contoured locking plate-and-screw implants for fixation of Danis-Weber Type B (OTA 44B) distal fibula lateral malleolar fractures in Saw-Bones models. Methods: This study utilized fibula Saw-Bones that were osteotomized to simulate a distal fracture and plated with one-third tubular or locking plates. Valgus bending and torsional tests were performed for each plated specimen. Results: A statistically significantly higher (P=0.001) peak load to failure during valgus bending was observed in specimens with anatomical locking plates over one-third tubular plates. There was no significant difference between the stiffness of the two plate constructs during valgus bending. The anatomically contoured plate construct withstood a significantly higher (P
