Summary
Giant cell tumors require complete excision to prevent recurrence. Microsurgical reconstruction with vascularized iliac crest bone grafts offers excellent functional outcomes and joint stability.
Area of Science:
- Orthopedic Oncology
- Microsurgery
- Bone Reconstruction
Background:
- Giant cell tumors are locally aggressive bone neoplasms with a high recurrence rate.
- Complete surgical excision is crucial for preventing recurrence.
- Tumor location near joints presents reconstruction challenges.
Purpose of the Study:
- To evaluate the efficacy of microsurgical reconstruction using vascularized iliac crest bone grafts for giant cell tumors.
- To assess recurrence rates and functional outcomes following aggressive tumor resection and reconstruction.
Main Methods:
- Retrospective analysis of 44 patients treated over 10 years.
- Complete tumor excision followed by reconstruction with vascularized iliac crest bone grafts.
- Application of microsurgical techniques for enhanced bone-to-bone incorporation.
Main Results:
- Low recurrence rate of 4.5% (2 out of 44 patients).
- Highly satisfactory functional results with excellent joint stability.
- Successful reconstruction of large bone defects, including juxtaarticular regions.
Conclusions:
- Microsurgical reconstruction with vascularized bone grafts is an effective method for managing giant cell tumors.
- Aggressive tumor resection combined with this technique leads to low recurrence and good function.
- This approach preserves joint integrity and stability, even in complex cases.
