[Cover of the Achilles tendon by peroneus brevis and flexor hallucis longus flaps. Apropos of 5 clinical cases]. / Le recouvrement du tendon calcanéen par les lambeaux de muscles court péronier et long fléchisseur de l'hallux. A propos de cinq cas cliniques.

Exposure of the Achilles tendon may be secondary to injury, trophic ulceration or surgical management of Achilles tendon rupture. We used peroneus brevis (PB) and flexor hallucis longus (FHL) muscle flaps to cover the Achilles tendon. The muscular portion of these muscles extends very distally, allowing their transposition to the Achilles region. PB and FHL are narrow (about 4 centimeters); the use of both muscles increases their possibilities of coverage. We used PB alone in one case and both muscles in four cases. In every case we obtained a good functional and cosmetic result. Various fascio-cutaneous flaps have been described for the reconstruction of the Achilles region. When there is an infection, muscle flaps are preferable to fascio-cutaneous flaps because they provide well vascularized tissue. We consequently suggest the use of PB and FHL to cover the Achilles tendon when it has been exposed for a long time or when it is infected. It seems especially indicated when skin necrosis occurs after surgical management of Achilles tendon rupture.
