Clinical Application of Artificial Dermis and Autologous Skin in Repairing Skin and Soft Tissue Defects of Hands and Feet with Bone Exposure Injuries

Patients with skin and soft tissue defects are very common. Mild trauma often causes mild skin damage, while severe injuries are often accompanied by bone and tendon exposure, which brings great pain to patients. For the defect of skin and soft tissue, the traditional treatment methods are mostly medium or full-thickness skin or skin flap transplantation. These methods are effective in wound repair, but there are still many problems. In recent years, with the improvement of tissue engineering technology, the use of artificial skin to repair various skin wounds is gradually becoming clinical, and the key technology of skin tissue engineering lies in the development of dermal substitutes. The appearance of artificial dermis not only solves the shortage of autologous skin source but also makes the operation simple and easy. The purpose of this study was to investigate the clinical effect of artificial dennis combined with autologous skin grafts in repairing hand and foot skin and soft tissue defects with bone exposure. The results show that the use of artificial dennis combined with autogenous blade thick skin to treat patients with hand and foot soft tissue injury with bone exposure has a good clinical effect, and the skin is alive and has fewer complications, which is worthy of promotion.
