Functional reconstruction of acutely burnt achilles tendon with composite anterolateral thigh flap with fascia lata: a case report.

Soft tissue defects in the postero-inferior aspect of the leg are still challenging, especially when they affect the Achilles tendon due to its important functional involvement in the normal movement of the ankle. Dorsiflexion and flexion may be affected if proper reconstruction is not achieved, thus limiting daily activities such as walking, climbing stairs or running. Several techniques, including local or regional flaps, combinations of tendon substitutes with free muscular or fasciocutaneous flaps, and free composite flaps with tendon have been described for the reconstruction of complex defects caused by burn sequelae, tumors, trauma, chronic ulcers, etc. The gold standard treatment for moderate to large defects is the anterolateral thigh (ALT) flap with vascularized fascia lata. The ALT flap is reliable because of a long vascular pedicle and a large donor area. Moreover, the fascia lata mimics the Achilles tendon perfectly when rolled on itself. The aim of this article is to present the application of this technique for the first time in a case of an acute burn. The timing of reconstruction with free flaps is critical in acute burns. In our case, it was performed on the 24th day post-burn and no microsurgical complications appeared. More than six months after surgery, the patient showed a normal gait, was able to lift his own weight against gravity and no complications were detected in the donor area.
