Abstract

Abstract:

BACKGROUND: Achilles tendon is placed in superficial position, and blood supply is few offered. Open injury leads to severe contamination, which is difficult to remove by complete debridement. Following the repair surgery, the infection, local skin defects and tendon exposure occur, change of dressing obtains unsatisfactory outcome.
OBJECTIVE: To investigate the clinical application of vacuum sealing drainage technique combined with reversed sural neurovascular pedicle flap to treat post-operative infection and skin of Achilles tendon.
METHODS: From 2009 to 2012, 13 patients with post-operative infection and skin of Achilles tendon were selected from the Second People’s Hospital of Foshan City, China, including 8 males and 5 females. The age of the involved patients was 25-65 years old. The accompanied soft tissue defects after ankle were ranged 4 cm×5 cm to 7 cm×6 cm, and repaired with repeated debridement and vacuum sealing drainage technique, until the wound granulation tissue was clean and the infection was controlled. The skin defects were repaired by reversed sural neurovascular pedicle flap. The healing of the wound was observed during follow-ups.
RESULTS AND CONCLUSION: All the patients were followed for 9-14 months. All the flaps survived completely in 13 patients, with good appearance, blood supply and texture. No secondary necrosis and infection was found. According to the AOFAS evaluation, the excellent rate of ankle joint function was 90% at post-operative 6 months. The wound infection can be effectively controlled by vacuum sealing drainage. The reversed sural neurovascular pedicle flap could provide a good covering for the exposed tendon and a flap with fine appearance, blood supply, texture and elasticity for soft tissue defects. The recovery of ankle joint functions is excellent, without local cicatricial contracture.
