Summary
Free latissimus dorsi flaps successfully reconstructed knee defects after malignant tumor removal. This surgical technique facilitated early patient ambulation and satisfactory knee function, demonstrating its efficacy in limb salvage surgery.
Area of Science:
- Orthopedic Oncology
- Microsurgery
- Reconstructive Surgery
Background:
- Malignant tumors of the distal femur pose significant reconstructive challenges.
- Limb salvage surgery aims to preserve function while removing tumors.
- Free tissue transfer offers a versatile option for complex defect coverage.
Purpose of the Study:
- To evaluate the efficacy of free latissimus dorsi flaps in reconstructing distal femur defects after malignant tumor resection.
- To assess the functional outcomes and success rates of this reconstructive technique.
Main Methods:
- Three patients with distal femur malignant tumors underwent tumor resection and knee prosthesis insertion.
- Free latissimus dorsi flaps were used to cover the knee prosthesis in all patients.
- Histopathological analysis confirmed osteosarcoma or fusiform cell sarcoma.
Main Results:
- Free latissimus dorsi flaps were successfully transferred in all three cases, despite prior neoadjuvant therapy.
- Prosthesis coverage was achieved immediately in two patients and delayed in one.
- Patients achieved ambulation at 6 weeks post-surgery with satisfactory knee function at 1-year follow-up.
Conclusions:
- Free latissimus dorsi flaps are a viable and effective method for reconstruction after distal femur tumor resection and knee prosthesis implantation.
- This technique supports early functional recovery and satisfactory outcomes in limb salvage surgery for lower extremity sarcomas.
