Summary
Limb-preserving surgery for pediatric malignant bone tumors is now successful using expandable modular prostheses. Newer electromagnetic field technology offers a promising, less invasive approach for limb lengthening.
Area of Science:
- Orthopedic Surgery
- Pediatric Oncology
- Biomedical Engineering
Background:
- Malignant bone tumors in children pose treatment challenges due to growth plate removal during surgery.
- Limb salvage techniques often face complications like limb expansion and length discrepancies.
- Advancements in modular expandable prostheses offer new solutions for reconstruction.
Purpose of the Study:
- To review current surgical treatments for malignant bone tumors in children.
- To emphasize reconstruction using expandable modular prostheses.
- To present the authors' experience with these devices.
Main Methods:
- Review of current surgical treatments for pediatric malignant bone tumors.
- Emphasis on reconstruction with expandable modular prostheses.
- Presentation of the authors' clinical experience.
Main Results:
- Thirty-seven children with malignant bone tumors underwent resection and reconstruction with modular prostheses.
- Fourteen patients had successful subsequent expansions using modular prostheses.
- A novel prosthesis utilizing an external electromagnetic field for lengthening was discussed.
Conclusions:
- Limb-preserving surgery for pediatric malignant bone tumors is achievable with modern expandable modular prosthetic devices.
- Expandable prostheses employing electromagnetic fields present a promising alternative to surgical interventions for lengthening.
