A new way of repairing special wounds

Abstract

PurposeWound repair has always been the basic method of burn surgery, but not all wounds in clinical work can regain both function and appearance. For relatively small wounds with irreversible functional damage accompanied by necrotic bone, joint and tendon exposure, and the wounds in non-functional sites with necrotic bone, tendon exposure and poor surrounding tissue conditions, the value and significance of tissue flap transplantation for wound repair are debatable. This paper discusses a new repair method as a supplementary choice for tissue flap transplantation: autologous granulation tissue and autologous thin split-thickness skin graft, which not only repairs the wound in a simple way but also avoids the cost of tissue flap transplantation. MethodsA total of 11 patients were collected from June 2019 to July 2022, with a total of 20 exposed wounds of bone, joint and tendon necrosis. During the operation, the necrotic exposed bone tissue and the completely necrotic tendon tissue were removed, and the necrotic soft tissue around the wound was completely excised until the wound appeared bleeding. We cut granulation tissue from other parts of the patient's body with a thickness of about 0.5–0.8 mm, cover the deep wound after thorough debridement with granulation tissue, and transplant autologous thin split-thickness skin to the deep wound covered with granulation tissue. The surgical area was compressed and immobilized. ResultsIn 11 patients, 20 wounds were surgically treated, and the wounds healed 15–25 days after the operation, and no bone tissue, joints, or tendons were exposed. No case underwent secondary surgery after surgery. Some wounds were treated with bedside allograft with the consent of the patient due to a small amount of residual granulation wound healing after transplantation. ConclusionUsing autologous granulation tissue and autologous thin split-thickness skin transplantation to repair some special wounds can not only repair the wounds simply and effectively but also avoid the cost of tissue flap transplantation.
