A new approach to heel ulcers: dorsalis pedis neurovascular trans-interosseous island flap.
The most important requisite in the care of ulcers in the heel region is replacement skin cover with adequate sensation. The dorsalis pedis flap appears adequate, but the anterior subcutaneous approach gives a pedicle of inadequate length to enable the flap to reach the most important posterior weight-bearing area. It was therefore decided to short-circuit the course of the pedicle by passing the whole flap through the interosseous membrane between the tibia and the fibula to enable the flap to reach the weight-bearing area without tension. After 10 meticulous cadaver and two post-traumatic limb dissections with angiographic confirmation, it appeared that such a flap was feasible and would satisfy all basic requirements. Clinically this technique was tried in two patients who were provided with sensate, well padded skin cover for the whole of the heel region.
