Abstract
Objective: To investigate the effectiveness of self-made limb chronic wound closure device in the treatment of scarred lower limbs and complex skin and soft tissue defects. Methods: Between January 2014 and January 2017, 29 patients with complex fractures of the lower extremities and skin and soft tissue defects were treated. There were 19 males and 10 females with an average age of 31.1 years (range, 21-66 years). The causes of injury included 14 cases of traffic accidents, 5 cases of falling from height, 4 cases of heavy object crushing injury, 4 cases of mechanical crushing injury, and 2 cases of exposed steel plate after fracture. There were 26 cases of calf fracture and skin defect, 3 cases of metatarsal bone fracture and skin defect of the foot. The skin defect ranged from 5 cm×3 cm to 18 cm×8 cm. The time from injury to admission was 5-31 days, with an average of 14.3 days. All patients underwent a thorough debridement, open wound drainage, self-made chronic wound closure device combined with Ilizarov stretching technique for a slow skin and soft tissue traction. After the wound was cleaned up and the granulation tissue was freshened, the skins on both sides were closed, and then proceed to the second stage operation of skin grafting or direct suture closure based on the size of the wound. Results: All patients were followed up 8-20 months, with an average of 13 months. Twenty-nine patients were treated with self-made chronic wound closure device combined with Ilizarov technique for 1-2 times with an average of 1.3 times, then the wound infection was controlled and the granulation tissue grew well. In the course of treatment, the pain was not obvious and the patients had good compliance. All patients' wounds healed clinically without skin traction complications and formed linear or flaky scars. Conclusion: The self-made chronic wound closure device is effective in repairing complex scarred wounds of lower extremities, and it is easy to operate.
