Summary
3D metal printing enables precise anatomical plates for proximal clavicle fractures. This innovative technology offers a new surgical solution with accurate screw placement for improved patient outcomes.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Additive manufacturing
Background:
- Proximal clavicle fractures are common injuries requiring surgical intervention.
- Traditional plates may have limitations in achieving optimal fit and screw placement.
- Virtual design and 3D printing offer potential for patient-specific implants.
Observation:
- A 52-year-old male volunteer's clavicle data was used for virtual design.
- A 1:1 scale clavicle model and anatomical plate were 3D metal printed.
- In vitro testing assessed plate fit and screw accuracy via imaging.
Findings:
- The 3D printed anatomical plate demonstrated excellent fit with the clavicle model.
- Accurate orientation and positioning of locking screws were confirmed by X-ray and CT.
- Fabrication times for the model, nail path design, and plate were recorded as 120, 15, and 300 minutes, respectively.
Implications:
- 3D metal printing provides a viable method for creating patient-specific proximal clavicle plates.
- This technology facilitates precise screw placement, enhancing surgical treatment for clavicular fractures.
- It represents a novel and accurate approach to managing proximal clavicular fractures.
