Abstract

Introduction: The fingers are functionally and cosmetically important. Deep burn on the hand frequently exposes joints, bones and tendons. The exposed bone and tendon wounds need to be covered early to avoid progressive necrosis.  Flap procedures are always the standard for managing complex soft tissue defects with exposed bones or tendons. In some areas,  these procedures are not technically possible. Vacuum-Assisted closure has been effectively applied in the treatment of exposed tendons and bone lesions that protect exposed tendons and bones avoiding secondary damage and preparing wounds for lesser reconstructive options. However, with finger bone tendon lesions, it is not easy to place negative pressure suction due to the anatomical characteristics of the finger area, especially children's fingers with small size.
Therefore, this technique has not been widely used on deep-burn hands. In this article, we introduce one of the successful cases when applying this therapy.
 Case presentation: His name is Pham Viet A., the 3-year-old male case was admitted to the pediatric burn department in the National Burns Hospital on August 28^th, 2020 with a diagnosis of 20cm² fifth-degree burn on 4 fingers of his right hand, except the thumb caused by low voltage electricity. He had undergone an operation to move necrosis, then Vacuum-Assisted Closure therapy (VAC therapy) was performed. The wound was closed and covered subsequently with split-thickness skin grafts- medium. The take graft was complete.
Conclusion: Negative pressure suction therapy can be applied effectively on the exposed tendon and bone lesions in children's fingers.
