Summary
This study shows a modular intramedullary fixation system provides good outcomes for limb salvage surgery in diaphyseal bone tumors. The system demonstrated satisfactory functional and oncological results in most patients.
Area of Science:
- Orthopedic Oncology
- Surgical Innovation
- Bone Tumor Treatment
Background:
- Diaphyseal bone tumors necessitate limb salvage surgery.
- Segmental bone defects pose reconstruction challenges.
Purpose of the Study:
- To evaluate the efficacy of a modular intramedullary diaphyseal segmental defect fixation system.
- To assess functional and oncological outcomes in patients undergoing limb salvage for diaphyseal bone tumors.
Main Methods:
- Six patients with primary or metastatic diaphyseal bone tumors underwent resection and reconstruction.
- A modular intramedullary diaphyseal segmental defect fixation system was utilized.
- Patients were followed for a mean of 17 months, with Enneking scores assessed.
Main Results:
- Five of six patients were disease-free at follow-up; one patient died with distant disease.
- One patient required revision surgery for proximal fixation loosening.
- A mean 87.8% increase in the Enneking rating score was observed postoperatively.
Conclusions:
- The modular intramedullary diaphyseal segmental defect fixation system offers satisfactory functional and oncological outcomes.
- This system is a viable option for limb salvage after wide resection of diaphyseal bone tumors.
