Hemipelvectomy for massive malignancy can result in large soft tissue defects that cannot be reconstructed using conventional posterior flaps. For such cases, reconstruction methods, including a latissimus dorsi flap or a rectus abdominis myocutaneous flap, may be applied, resulting in donor site morbidity. Recent innovations in plastic surgery have resulted in the development of novel reconstruction modalities based on "the spare part concept," applying tissues from amputated limbs. ⋯ The femoral artery-based myocutaneous flap and the free fillet lower leg flap are both useful, safe options for reconstruction of the large defect following extensive hemipelvectomy for malignant bone and soft tissue tumors. The present data support the continued application of these flap reconstruction techniques based on the spare part concept.
