Heel coverage using a distally based sural artery fasciocutaneous cross-leg flap: report of a small series.

UNLABELLED: One of the goals in the management of severe open injuries of the foot is to obtain adequate soft tissue coverage. In extreme conditions of pedal soft tissue loss, in patients who are not satisfactory candidates for local or free-tissue transfer, the cross-leg flap remains an option for surgical reconstruction. We present the results of 7 patients with multiple lower limb open fractures associated with ipsilateral degloving injuries, and/or secondary pressure ulcers of the hindfoot with exposure of the calcaneus, in which a distally based sural artery island fasciocutaneous flap, elevated from the contralateral leg and crossed to the injured side, was used to repair the soft tissue defect of the recipient heel. All of the flaps survived and the soft tissues healed uneventfully, thereby providing satisfactory and stable coverage of the calcaneal tuberosity. To the best of our knowledge, this is the first report in which this technique has been used to repair hindfoot soft tissue defects associated with complex bone and vascular injuries of the lower limb in polytrauma patients. LEVEL OF CLINICAL EVIDENCE: 4.
