Massive posttraumatic defects of the foot in 4 patients and a tibial m
alunion in another were repaired by flow-through anterior (anterolater
al and anteromedial) thigh flaps. Posterior tibial vessels were used a
s the recipient vessel just below the level of the medial malleolus. S
oft-tissue defects in foot-injured patients were covered with flow-thr
ough anterior thigh flaps interposing the descending branch of the lat
eral circumflex femoral system between the transected posterior tibial
vessels. In another patient, a combined anteromedial thigh flap and v
ascularized iliac bone cross-leg ''chimeric'' flap were successfully t
ransferred 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 femora
l system facilitates revascularization of ischemic areas and simultane
ous transplantation of multiple components, as well as preserves recip
ient vessels. Owing to the stable blood supply, these flaps can be rea
dily processed into both deepithelialized and thin flaps.
