Composite free fibula flap and bone allograft for calcaneus reconstruction: A rare case.

Calcaneus sarcomas are extremely rare, but often nefarious. Its weight-bearing function makes reconstruction after calcanectomy exceptionally difficult, demanding a solid, stable and well-padded substrate. We report a 69 years-old female with a rare small-round-cell sarcoma in her left ankle, submitted to total calcanectomy and reconstruction with a composite calcaneus allograft and free fibula flap. After 36 months, the bone healed evenly with no limitations in her daily life. This advantageous combination of vascularized bone with allograft, allowed biological integration with the strengthful external construct, representing one of the best limb-sparing options for the calcaneus.
