    Abstract:
    The medial plantar flap serves as an ideal tissue reserve for reconstructing the weight-bearing plantar areas as these areas require a sensate and glabrous skin. Furthermore, the flap provides tissue that is structurally similar to the plantar foot as it is also composed of thick glabrous plantar skin, shock-absorbing fibro-fatty subcutaneous tissue and plantar fascia. During the past 25 years, 20 patients (10 men, 10 women) with skin and soft-tissue defects over the weight-bearing plantar foot were treated. They ranged in age from 20 to 70 years (mean, 31.5 years). The causes of the defects were trauma (n=14) and malignant tumour (n=6); the defects were localised at the heel (n=16) and plantar forefoot (n=4). The medial plantar flap was transposed to the defects in three different ways: proximally pedicled sensorial island flaps (n =8), distally pedicled sensate island flaps based on the lateral plantar vessel (n =3) and neurovascular free flaps (n =9). Flap size varied from a width of 4-8cm and a length of 6-12cm. The mean size of the medial plantar flap was 49.5cm(2) (range, 28-96cm(2)). The follow-up period ranged from 6 to 80 months (mean, 19.9 months). Partial flap loss was observed in two proximally pedicled sensorial island flaps and one distally pedicled sensate island flap. Two free flaps restored normal sensation within 5 years of surgery. Minor skin graft loss at the donor site was observed in seven patients. However, no revision or re-grafting was performed. Hyperkeratosis was observed in one case. All patients achieved normal gait within 3 months after surgery and none noticed recurred ulceration. Durable, sensate coverage of the defects was achieved in all patients. We advocate variable sensate medial plantar flaps for the reconstruction of moderate-size defects of the weight-bearing plantar subunits.
