Case:
An 18-year-old woman with osteosarcoma of the left distal femur underwent resection and limb-salvage surgery with compressive osseointegration endoprosthetic reconstruction and experienced tumor recurrence 1 year after index surgery. A transfemoral amputation was performed preserving the existing compressive osseointegration device, and limb lengthening was achieved using intercalary and distal femoral segments. 3.5 years after amputation and lengthening, the implant remains well integrated and the patient is ambulatory.
Conclusion:
Compressive osseointegration with distal femoral endoprosthesis is a viable option for adding length and lever arm mechanics in patients with short stump above knee amputations.
