In Paulick 2022 et al., on feline ilial plating, which of the following statements best describes the failure mode observed in **locking plate constructs**?
A. Screw loosening was common in sacral screws
B. Bone slicing occurred in all specimens
C. Implants failed by corrosion
D. Catastrophic screw pull-out was seen in 50%
E. Loosening was rare in locking plates
Answer: Bone slicing occurred in all specimens
Explanation: Locking constructs consistently failed via bone slicing, not screw loosening.
In Paulick 2022 et al., on feline ilial plating, which failure mode occurred in **100% of specimens** using **nonlocking DCP plates**?
A. Implant fracture
B. Plastic deformation
C. Bone slicing
D. Screw loosening
E. Plate bending
Answer: Screw loosening
Explanation: DCP constructs consistently failed by screw loosening, unlike locking plates.
In Paulick 2022 et al., on feline ilial plating, which implant system demonstrated the **lowest bending stiffness** under cyclic loading?
A. ALPS-6.5
B. FIXIN
C. DCP
D. ALPS-5
E. LCP
Answer: ALPS-5
Explanation: ALPS-5 constructs had significantly lower stiffness than all other groups.
In Paulick 2022 et al., on feline ilial plating, what factor most contributed to the **poor performance** of the ALPS-5 system despite it being a locking plate?
A. Incorrect torque application
B. Improper screw insertion
C. Too many empty screw holes
D. Small cross-section of the plate
E. Inferior screw thread design
Answer: Small cross-section of the plate
Explanation: ALPS-5 failed more often due to its reduced moment of inertia, despite angular stability.
In Paulick 2022 et al., on feline ilial plating, which implant groups endured **more cycles** and **greater load** before displacement compared to DCP?
A. ALPS-5 and FIXIN
B. FIXIN and LCP
C. LCP and ALPS-5
D. ALPS-6.5 and ALPS-5
E. DCP and FIXIN
Answer: FIXIN and LCP
Explanation: Only FIXIN and LCP showed statistically superior performance over DCP in load cycles before displacement.
