🔍 Key Findings
- NAS-ILN had significantly greater stiffness in both axial compression and 4-point bending compared to LCP constructs.
- Ultimate load to failure was significantly higher for NAS-ILN in compression (804 N vs 328 N) and bending (25.7 Nm vs 16.3 Nm).
- Torsional stiffness and angular deformation were similar, but NAS-ILN resisted higher torque to failure than LCP (22.5 Nm vs 19.1 Nm).
- No slack was observed with the NAS-ILN construct, unlike older nail designs.
- Failure modes differed: LCPs failed via plate bending; NAS-ILNs failed at the implant or bone near screw holes.
- Titanium alloy and curved design of NAS-ILN provides better anatomic fit and more uniform stress distribution.
- A third, perpendicular locking hole in NAS-ILN may enhance torsional stability but was not utilized in this study.
- The curved, angle-stable design of NAS-ILN is a novel advancement in veterinary orthopedics.
