[Analysis of the vacuum sealing drainage technique combined with sural neurovascular pedicle fascio-cutaneous flap to repair deep wounds in the foot near the ankle joint with exposed bone and tendons].

Objective:To evaluate the practical method of vacuum sealing drainage(VSD) technique combined with sural neurovasculr pedicle fasciocutaneous flap to repair deep wounds in the foot near the ankle joint with exposed bone and tendons.Methods:From January 2006 to January 2009,79 patients with deep wounds in the foot near the ankle joint with exposed bone and tendons were treated by VSD technique combined with sural neurovasculr pedicle fasciocutaneous flap including 58 males and 21 females with an average age of 34 years old ranging from 7 to 59 years.There were 17 cases in low 1 / 3 part of leg and achilles tendon,28 in lateral malleolus and lateral dorsum of foot,21 in medial malleolus and medial dorsum of foot,13 in heel and pelma.Firstly the wounds were debrided and cultivated by using VSD technique,then the soft tissue defections were re-paired with sural neurovasculr pedicle fasciocutaneous flap.Results:The area of flap was from 6 cm×5 cm to 18 cm × 15 cm;All patients stayed in hospital for 14 to 30 days,18 days in average.Living flaps of all patients were followed up from 6 months to 3 years,the flaps of 2 patients were mostly necrotic,3 were necrotic,5 cases appeared obstacle of venous back streaming.The others survived with no infections.Conclusion:The wound would become fresh and clean as soon as possible with VSD.The sural neurovasculr pedicle fasciocutaneous flap could provide a good covering for the exposed wound.Therefore the wound healed faster with friction resistance and fine appearance.The time of hospitalization were greatly shortened after combined ap-plication.
