ObjectiveTo investigate the effectiveness of wide fascial and doubly vascularized pedicle posterior cnemis flap in repair of the soft tissue defect of forefoot.MethodsBetween March 2011 and March 2017, 18 cases with severe soft tissue defects of forefeet were repaired with the wide fascial and doubly vascularized pedicle posterior cnemis flaps. There were 13 males and 5 females with an average age of 33 years (range, 11-49 years). Of 18 cases, the defects were caused by trauma in 16 cases with an average disease duration of 15 hours (range, 3-72 hours), by infection after correction of spastic clubfoot in 1 case, and by infection after open fracture fixation in 1 case. The defects were on the planta of forefoot in 11 cases and on the dorsum of forefoot in 7 cases. The size of soft tissue defects ranged from 6 cm×4 cm to 15 cm×9 cm. All defects combined with the bone, joint, and tendon exposures and 4 defects combined with fractures. The size of flaps ranged from 8 cm×5 cm to 17 cm×10 cm. All wounds of donor sites were repaired by skin grafting.ResultsThe operation time was 100-190 minutes (mean, 140 minutes). Seventeen flaps survived and wounds healed by first intention. One flap had partial necrosis and cured after dressing change. Seventeen cases were followed up 5-24 months (mean, 16 months). Both the color and texture of the flaps were satisfactory. But the pedicles of flaps were swollen. The functions of foot and ankle returned to normal.ConclusionThe wide fascial and doubly vascularized pedicle posterior cnemis flap has reliable blood supply and sufficient venous reflux to ensure its survive, which can be used to repair severe soft tissue defect of forefoot.
