Peroneal artery perforator chimeric flap for reconstruction of composite defects in extremities.
Large bone defects of extremities, especially those associated with soft tissue defects, represent difficult reconstructive problems. Chimeric flap is a suitable option for reconstruction of complex bone and soft-tissue defects. In this report, we present the experience on use of the peroneal artery perforator chimeric flap for the reconstruction of complex bone and soft tissue defects in the extremities in 16 patients. The bone defects were located in the tibia in 8 patients, in both tibia and fibula in 1 patient, in the ulna in 2 patients, in both ulna and radius in 2 patients, and the metatarsal bone in 3 patients. The flap was created with skin paddle and fibula bone segments based on independent perforators. The sizes of flap ranged from 8 x 6 to 20 x 11 cm(2), and the length of fibular grafts ranged from 6 to 22 cm. All flaps survived completely. Bone union was ultimately obtained in all cases at 5 to 11 months, while two cases suffered from stress fractures in 12 month and 18 month after operation, respectively, which eventually healed with external fixation treatment. The follow-up time ranged from 12 to 37 months. The definite bone hypertrophy was observed from X-ray at 18 months after operation. In conclusion, our results show that the peroneal artery perforator chimeric flap is a good option for reconstruction of complex bone and soft-tissue defects of extremities, particularly for those with three-dimensional defects and bone defects exceeding 6 cm in length.
