3D printing method for next-day acetabular fracture surgery using a surface filtering pipeline: feasibility and 1-year clinical results
Clinical Scorecard: Next-Day Acetabular Fracture Surgery Utilizing 3D Printing with a Surface Filtering Pipeline: Feasibility Study and One-Year Clinical Outcomes
At a Glance
Category
Detail
Condition
Acetabular fractures requiring surgical treatment
Key Mechanisms
Use of semiautomatic 3D printing from CT data to create anatomically accurate, fracture-segmented models for preoperative planning and implant pre-bending
Target Population
Patients with acetabular fractures treated surgically at a level 1 trauma center
Care Setting
Orthopedic trauma surgery with next-day operative scheduling
Key Highlights
3D printed fracture models enable ergonomic haptic exploration, improved understanding, and surgical planning of complex acetabular fractures.
Pre-bent steel reconstruction plates sterilized overnight based on the 3D model reduce intraoperative bending time and potentially improve implant fit.
A semiautomatic, in-house 3D printing workflow using open-source software (3D Slicer) and affordable hardware can produce fracture models within 24 hours.
Guideline-Based Recommendations
Diagnosis
Obtain high-resolution CT imaging with submillimeter slice thickness (0.5–1.25 mm) for detailed fracture visualization.
Use threshold-based segmentation (200–350 HU) to differentiate bone structures from soft tissue.
Management
Utilize 3D printed fracture models to plan fracture reduction strategy and pre-contour osteosynthesis plates.
Sterilize pre-bent plates overnight for use in next-day surgery to streamline operative workflow.
Monitoring & Follow-up
Assess intraoperative parameters such as operation time and blood loss to evaluate clinical benefits of 3D printed model use.
Follow clinical outcomes over one year to validate feasibility and effectiveness.
Risks
Potential inaccuracies in mirrored models may impair reduction and implant placement; thus, fracture-segmented models are preferred.
Labor-intensive model creation may limit routine use without semiautomatic workflows.
Patient & Prescribing Data
Consecutive patients with acetabular fractures undergoing surgical fixation at a level 1 trauma center
3D printed models facilitate preoperative planning and implant preparation, potentially reducing operative time and improving surgical outcomes.
Clinical Best Practices
Implement semiautomatic segmentation and surface filtering pipelines to reduce labor and time in model creation.
Use open-source software (3D Slicer) combined with custom extensions to generate printable fracture models.
Ensure fracture fragments are clearly separated and artifact-free to allow model flexibility and accurate pre-bending of plates.
Produce and sterilize pre-bent implants within 24 hours to enable next-day surgery.
