The skin and soft tissue defects or ulceration of the wight-bearing part of the sole was difficult to repair with medial plantar island flap, but would be treated with retrograde island flap carrying plantar metatarsal arteries as pedicle. Ten flaps were applied in 9 patients. They had either indolent ulcer or skin defect secondary to excision of painful corn or callosities of the front part of the sole. The flaps were 3 cm to 5 cm long and 3 cm to 4 cm wide, and they all survived following retrograde transfer. The patients were followed up for 1 to 10 years. It was found that the patients could bear weight on the operated foot and could walk without pain or lameness. The flaps were resistant to abrasion from long-time walking. It was concluded that this kind of flap was best suitable to repair the ulcers and defects over the front part of the sole despite there were some minor shortcomings such as the size of the flaps available was small and the donor site required split skin graft for coverage.
