Case: A 23-year-old woman sustained a skin defect in the anterior ankle involving the extensor retinaculum (ER) and 10 cm of extensor tendons (ETs) after a wide resection of clear cell sarcoma. The skin defect was reconstructed with free latissimus dorsi flap, ER with tensor fascia lata, and ETs with 2-staged tendon reconstruction using silicone rod interposition, followed by semitendinosus and gracilis tendon grafts. Four years postoperatively, she achieved 92% of ankle and 70% of great toe motion of the contralateral side.
Conclusion: This reconstruction technique was useful for a large soft-tissue defect at the anterior ankle.
