Lengthening the Transfemoral Amputation Stump Using Vascularized Flap From Amputated Limb: A Case Report.

CASE

A 10-year-old male patient was diagnosed with osteosarcoma and initially underwent prosthetic reconstruction following an extra-articular resection. Local recurrence with extensive neurovascular invasion necessitated the decision to perform a transfemoral amputation. To maximize functional outcome through lengthening the stump, a tibial osseocutaneous vascularized flap from the amputated limb was integrated into amputation stump, utilizing plate-and-screw fixation. At the final follow-up, the patient was independently ambulatory using a custom-made prosthesis.

CONCLUSION

We present a patient operated with a novel technique to increase transfemoral amputation stump length for recurrent osteosarcoma by using an osseocutaneous flap reconstruction.
