[Case report: Great toe dorsal defect reconstruction by cross-toe flap]. / Cas clinique : reconstruction d'une perte de substance de la face dorsale de l'hallux par lambeau cross-toe.

Reconstruction of hallux soft-tissue defects is essential for the locomotor function. Some regional flaps are available and have to be preferred in case of small defect. Here, we present the case of a patient treated by a cross-toe flap in order to cover an exposed hallux proximal interphalangeal joint, after an open fracture. The functional outcome of this reliable and easy flap was very satisfying, with quick wound healing and resumption walk.
