Reconstruction of posttraumatic defects of the foot by flow-through anterolateral or anteromedial thigh flaps with preservation of posterior tibial vessels.
Massive posttraumatic defects of the foot in 4 patients and a tibial malunion in another were repaired by flow-through anterior (anterolateral and anteromedial) thigh flaps. Posterior tibial vessels were used as the recipient vessel just below the level of the medial malleolus. Soft-tissue defects in foot-injured patients were covered with flow-through anterior thigh flaps interposing the descending branch of the lateral circumflex femoral system between the transected posterior tibial vessels. In another patient, a combined anteromedial thigh flap and vascularized iliac bone cross-leg "chimeric" flap were successfully transferred for the reconstruction of a malunion of a tibial fracture, which had been accompanied by severe vascular damage to the thigh. The utilization of derivative branches from the lateral circumflex femoral system facilitates revascularization of ischemic areas and simultaneous transplantation of multiple components, as well as preserves recipient vessels. Owing to the stable blood supply, these flaps can be readily processed into both deepithelialized and thin flaps.
