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.
