Summary
Simulated surgery using 3D models accurately corrected complex ankle deformities in Maffucci syndrome. This technique enhances pre-operative planning and improves surgical outcomes for limb deformities.
Area of Science:
- Orthopedic Surgery
- Medical Imaging
- Biomechanical Engineering
Background:
- Maffucci syndrome can cause complex valgus ankle deformities.
- Accurate pre-operative planning is crucial for correcting such deformities.
Observation:
- A 24-year-old male with Maffucci syndrome presented with a complex right ankle valgus deformity.
- Computed tomography (CT) data was used to create a life-size 3D plastic model of the affected ankle.
Findings:
- A simulated osteotomy was performed on the 3D model to understand the anatomical deformity.
- The actual three-dimensional osteotomy and subsequent limb lengthening accurately corrected the valgus and recurvatum deformities.
Implications:
- Simulated surgery using 3D models offers a valuable pre-operative planning tool.
- This approach enhances the accuracy of surgical correction for complex limb deformities.
