Summary
The Saddle endoprosthesis offers a stable joint for patients with pelvic bone tumors. This study shows good functional outcomes in most patients, with five disease-free survivors.
Area of Science:
- Orthopedic surgery
- Oncology
- Biomedical engineering
Background:
- Pelvic bone tumors require complex surgical management.
- Reconstruction of the pelvis after tumor resection presents significant challenges.
- The Saddle endoprosthesis is designed for pelvic-femoral articulation.
Purpose of the Study:
- To evaluate the safety and efficacy of the custom-made Saddle endoprosthesis.
- To assess functional outcomes in patients undergoing pelvic tumor resection and reconstruction.
- To report oncological results following the use of this endoprosthesis.
Main Methods:
- Six patients with malignant or aggressive benign bone tumors of the pelvis underwent resection.
- Custom-made Saddle endoprostheses were used for reconstruction.
- Surgical margins (wide or marginal) were assessed, and patient follow-up ranged from 24 to 41 months.
Main Results:
- All six patients survived the follow-up period.
- Five patients were disease-free at the end of the study.
- Excellent or good functional results were achieved in five patients.
- One patient experienced deep infection and local recurrence, requiring prosthesis removal.
Conclusions:
- The Saddle endoprosthesis can provide stable and functional pelvic-femoral articulation after tumor resection.
- It offers a viable reconstructive option for selected patients with pelvic bone tumors.
- Careful patient selection and surgical technique are crucial for optimal outcomes.
