Threshold screw insertion torque for carbon fibre-reinforced polyetheretherketone and titanium (Ti-6Al-4V) locking plate constructs

Beyond an initial threshold (∼0.5 Nm), increased insertion torque did not consistently enhance construct performance. These findings indicate that moderate torques (∼1.5 Nm) optimise performance while reducing the risk of implant damage, support the mechanical reliability of CFR-PEEK plates.
