Objective  To explore the effectiveness of changeable cross-leg style sural neurovascular flap in repairing contralateral fairly large soft tissue defects on dorsum of forefoot. Methods  Between June 2006 and June 2015, 12 patients with fairly large soft tissue defect on dorsum of forefoot were treated. There were 8 males and 4 females, with an average age of 35.6 years (range, 18-57 years). Defects were caused by traffic accident injury in 4 cases, machine crush injury in 3 cases, and heavy object crush injury in 3 cases, with a median disease duration of 11 days (range, 5 hours to 28 days) in the 10 cases; the defect cause was atrophic scar in 2 cases, with disease duration of 2 years and 3 years respectively. The wound size of soft tissue ranged from 6.2 cm×4.1 cm to 11.5 cm×7.4 cm; combined injuries included tendon exposure in all cases and bone exposure in 6 cases. The changeable cross-leg style sural neurovascular flaps were used to repair defects. The width and length of flap pedicle were increased. The cross-leg position was maintained with the elastic net bandage. The size of flaps was 16 cm×7 cm to 21 cm×11 cm, with a pedicle of 8-16 cm in length and 5-6 cm in width. Results  After operation, 10 flaps survived, and wound healed by first intention. Extravasated blood occurred at the flap edge in 2 cases and was cured after symptomatic treatment. No pressure sore occurred. All patients were followed up 3-24 months (mean, 7 months). The appearance and function of the affected legs were good, and the flaps had soft texture and normal color. Conclusion  Changeable cross-leg style sural neurovascular flap can achieve good effectiveness in repairing fairly large soft tissue defect on dorsum of forefoot. Some drawbacks of single cross-leg style can be avoided.
