Pasteurized intercalary autogenous bone graft combined with vascularized fibula

Area of Science:

• Orthopedic Surgery
• Oncology
• Regenerative Medicine

Background:

• Reconstruction after wide bone tumor resection presents challenges.
• Optimal methods for restoring bone integrity and function are debated.

Purpose of the Study:

• To evaluate the efficacy of pasteurized intercalary autogenous bone graft combined with vascularized fibula graft.
• To assess bone union rates and functional outcomes in patients with malignant bone tumors.

Main Methods:

• Retrospective review of 15 patients undergoing reconstruction with pasteurized autogenous bone and vascularized fibula grafts.
• Analysis of bone union duration, complications, and Musculoskeletal Tumor Society (MSTS) scores.

Main Results:

• Mean union time for pasteurized bone was 13.5 months; for vascularized fibula, 7.7 months.
• Complete union achieved in 86.7% of patients; infection complicated union in two cases.
• MSTS scores averaged 80.6%, comparable to alternative reconstructive techniques.

Conclusions:

• Pasteurized autogenous bone graft with vascularized fibula graft is a promising option for selected patients with large bone defects.
• This combined approach can achieve satisfactory bone union and functional results.
• Careful patient selection is crucial for successful outcomes.
