Summary
Three-dimensional (3D) printed spine models reduce surgical planning time for complex spinal deformities. While not significantly altering operative plans, these models offer valuable practice opportunities for surgeons using implants.
Area of Science:
- Orthopedic Surgery
- Medical Imaging
- Biomedical Engineering
Background:
- Complex spinal deformities present significant challenges for surgical planning.
- Accurate pre-operative assessment is crucial for optimizing surgical outcomes.
Purpose of the Study:
- To evaluate the impact of 3D printed models on pre-operative surgical planning for complex spinal deformities.
- To compare the efficacy of 3D printed models against traditional imaging methods.
Main Methods:
- Five orthopedic surgeons planned surgeries for five patients with severe spinal deformities.
- Planning was conducted using three modalities: X-ray with computed tomography (X-ray-CT), 3D computed tomography (3D-CT), and 3D printed spine models.
- Surgical plans were assessed based on instrumentation levels, osteotomy sites, and decision-making time.
Main Results:
- No statistically significant differences were found in the number of screws or osteotomy scores between the methods.
- Decision-making time was shortest with 3D printed models, followed by 3D-CT, and then X-ray-CT.
Conclusions:
- 3D printed models do not significantly alter the operative plan for complex spinal deformities.
- These models substantially reduce pre-operative surgical planning time.
- 3D models provide a valuable platform for practicing implant placement on patient-specific anatomy.
