  • REVERSED FASCIA PEDICLED PERONEAL PERFORATING BRANCH SURAL NEUROFASCIOCUTANEOUS FLAP FOR REPAIRING SOFT TISSUE DEFECT IN DORSAL PEDIS

    Objective To summarize the cl inical experience of repairing soft tissue defect in dorsal pedis with reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flap, and to explore surgery matters needingattention and measures to prevent flap necrosis. Methods Between August 2000 and April 2009, 31 patients with soft tissue defects in dorsal pedis were treated with reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flaps. There were 23 males and 8 females with a median age of 34 years (range, 3-65 years). Defects were caused by traffic accident in 20 cases, by machine in 2 cases, and by crush in 2 cases. The time from injury to admission was 1-32 days (mean, 15 days). And 6 cases had chronic ulcer or unstable scar excision with disease duration of 6 months to 10 years, and 1 case had squamous carcinoma with disease duration of 5 months. The wounds were located in medial dorsal pedis in 12 cases and lateral dorsal pedis in 19 cases; including 14 wounds near the middle metatarsal and 17 wounds beyond the middle metatarsal (up to the metatarsophalangeal joint in 10 cases). All cases accompanied with bone or tendon exposure. Five cases accompanied with long extensor muscle digits tendon rupture and defect, 1 case accompanied with talus fracture, 1 case accompanied with talus fracture and third metatarsal fracture. The size of the wounds ranged from 6.0 cm × 4.5 cm to 17.0 cm × 10.0 cm. The size of the flaps ranged from 8.0 cm × 5.5 cm to 20.0 cm × 12.0 cm. The donor sites were resurfaced by skin graft. Results Seventeen flaps survived uneventfully, wounds healed by first intention. Distal epidermal or superficial necrosis occurred in 6 flaps at 5-12 daysafter operation, wounds healed by dressing change or skin graft. Distal partial necrosis occurred in 8 flaps (7 in medial dorsal pedis and 1 in lateral dorsal pedis) at 7-14 days after operation, wounds healed by skin graft in 3 cases, by secondary suture in 3 cases, by local flap rotation in 1 case, and by cross leg flap in 1 case. All skin grafts at donor sites survived uneventfully, wounds healed by first intention. Twenty-nine patients were followed up 6-29 months (mean, 19 months). The appearance was sl ightly overstaffed, but wearing shoe function and gait were normal. The texture and color of the flaps in all cases were good. There was no pigmentation and suppuration relapse. There was neither ankle plantar flexion deformity nor hammer toe deformity in 5 cases accompanied with long extensor muscle digits tendon rupture and defect. All fractures healed at 3 months after operation in 2 cases. Conclusion The reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flaps are suitable to repair most soft tissue defects in lateral dorsal pedis. When the flaps are used to repair soft tissue defects in medial dorsal pedis, avoiding tension in flaps and fascia pedicles should be noted so as to improve flap survival.
