Summary
Custom 3D-printed guides significantly reduce surgical time and fluoroscopy use for equine navicular bone screw placement. This innovative approach enhances surgical efficiency without compromising screw accuracy in veterinary procedures.
Area of Science:
- Veterinary Surgery
- Biomechanical Engineering
- Orthopedics
Background:
- Cortical bone screw placement in equine navicular bones is a critical surgical procedure.
- Traditional methods for screw placement can be time-consuming and involve significant radiation exposure.
Purpose of the Study:
- To evaluate the efficacy of a custom 3D-printed guide for equine navicular bone screw placement.
- To compare surgical duration and radiation exposure between 3D-printed guides and traditional aiming devices.
Main Methods:
- An ex vivo study utilizing eight pairs of adult equine forelimbs.
- Cortical screws were placed in the navicular bone using either a 3D-printed guide or a traditional aiming device.
- Surgical time, fluoroscopy image count, and screw placement accuracy were assessed.
Main Results:
- The 3D-printed guide significantly reduced surgical duration by an average of 6.6 minutes (p < .01).
- Fewer fluoroscopy images were required with the 3D guide (18 vs. 40, p < .01).
- No significant difference in navicular screw placement accuracy was observed between the two methods.
Conclusions:
- 3D-printed guides offer a more efficient method for placing screws in equine navicular bones.
- This technology reduces operative time and radiation exposure without compromising surgical outcomes.
- 3D-printed guides have potential applications in surgical training and practice for improved efficiency and safety.
