Feature Question

(OBQ10-33) A surgeon chooses a periarticular locking plate with unicortical proximal locking screws for an extra-articular distal femur fracture as seen in Figure A. Compared to an identical construct with bicortical unlocked proximal screw fixation, the periarticular locking plate with unicortical locking screws has which biomechanical properties? REVIEW TOPIC
FIGURES: A          

1. Greater torsional and axial fixation strength
2. Less torsional but greater axial fixation strength
3. Equal torsional and axial fixation strength
4. Greater torsional but less axial fixation strength
5. Less torsional and axial fixation strength
