Abstract:
Objective:To explore the clinical technique and method of reconstruction large soft tissue defect of plantar by skin soft tissue dilatation combined with thigh cross leg flap to improve the weight-bearing function of plantar standing.Methods:From February 2015 to June 2019, 8 cases with plantar soft tissue defects were repaired with cross leg flap expanded from the healthy side of the thigh. Right foot in 4 cases, left foot in 3 cases and bilateral in 1 case. There were 5 males and 3 females. Ages ranged from 16 to 56, with an average age of 31. Clinical features: scar ulcer in 4 cases, bone-sticking scar in 4 cases, bone exposure in 1 case. After debridement, the area of skin and soft tissue defect was 9 cm×16 cm-12 cm×29 cm, the area of harvest expanded flap was 11 cm×18 cm-14 cm×30 cm. All flaps were fixed by cross-leg with pedicle. The pedicle division were performed one month after the skin flap transmission.Results:Of the 9 flaps transferred, 8 survived, 1 died in the distal part of the flap and was repaired by secondary expanded flap, and the donor site healed in linear scar stage. After 6-24 months follow-up, the plantar flap was in good shape and could walk with weight-bearing, without ulceration, and the protective tactile sensation was gradually restored in 12 months.Conclusions:The large-area soft tissue defect of plantar was repaired with the expanded cross leg flap in the healthy thigh, which also provide sufficient thickness of soft tissue to increase the ability of bearing weight and wearing resistance of the sole. It is a good alternative method to repair large area soft tissue defect of plantar under the condition of limited transfer of perforator flap and free flap.
