WebJan 2, 2024 · Biomechanics of Plate Fixation • The screws closest to the fracture see the most forces. • The construct rigidity decreases as the distance between the innermost screws increases. Screw Axial Force. Biomechanics of Plate Fixation • Number of screws (cortices) recommended on each side of the fracture: Forearm 3 (5-6) Humerus 3-4 (6-8 ... WebJun 10, 2024 · 10.1055/b-0035-122010 10 Biomechanics of Fracture Fixation Peter Augat The basic requirements for successful treatment of bone fractures have long been identified by Lorenz Böhler: reposition, retention, and rehabilitation. The fixation of the fracture has to respect these requirements and has therefore to provide sufficient biomechanical stability.
