Methods: We suggest 2 connected free flaps (posterior tibial artery flap and medial plantar flap) pedicled with 1 set of vessels. The medial plantar flap was used to cover the skin defect of the weight-bearing area in the forefoot. The dorsal skin defect of the injured foot was covered with a posterior tibial artery flap and supplied the medial plantar flap with the posterior tibial vessel. The midfoot skin defect was repaired by a full-skin grafting.
Results: Long-term follow-up results showed that the shape and function of the injured limbs recovered almost entirely.
Conclusion: This method of connected flaps is suitable for repairing large skin defects of the fore–mid foot.
