Customized 3D-printed component-preserving reconstruction for femoral neck fracture revision in a long-term survivor of pediatric osteosarcoma: a case report
Clinical Report: Tailored 3D-printed reconstruction for femoral neck fracture
Overview
Revise to include the significance of limb-length improvement and functional recovery metrics.
Background
Osteosarcoma is a prevalent malignant bone tumor in children, often leading to complex surgical challenges due to skeletal development issues post-treatment. Periprosthetic fractures in survivors with tumor prostheses are particularly difficult to manage, necessitating innovative reconstruction strategies to avoid extensive surgeries like total femoral replacement.
Data Highlights
The patient experienced a limb-length discrepancy reduction from 20 cm to 15 cm postoperatively. The Harris Hip Score improved from 63 at 3 months to 81 at approximately 6 months, indicating significant functional recovery.
Key Findings
Customized component-preserving reconstruction can be a viable alternative to total femoral replacement.
The use of a socket-type prosthesis-to-prosthesis coupling design enhances stability in complex femoral defects.
Hybrid fixation methods, including vancomycin-loaded PMMA cement, improve surgical outcomes.
Long-term follow-up is essential to assess the durability and complications of such innovative reconstructions.
Functional recovery metrics, such as the Harris Hip Score, indicate positive outcomes in this patient population.
Clinical Implications
Surgeons should consider component-preserving techniques in patients with stable distal tumor prostheses to minimize surgical trauma and enhance recovery. This approach may lead to improved functional outcomes and reduced complications compared to traditional total femoral replacement.
Conclusion
The case highlights the potential of tailored 3D-printed reconstructions in addressing complex femoral defects while preserving existing stable components. Further studies are needed to validate these findings and establish long-term efficacy.
