Abstract

Background: Skin defects and tissue organization are common injuries due to various causes such as trauma, postoperative removal of skin lesions (bone combination, open fractures, tumors, burns). Due to the anatomical characteristics of the lower legs, ankles often thin skin, poor blood vessels, little stromal tissue and muscle, immediately below is the bone tendon structure, it is very easy to necrotize the skin or lose skin to expose tendons, bones, joints, blood vessels, nerves. This increases the risk of infection, if not treated early, properly will lead to necrosis, tendon sticking, osteoarthritis, arthritis, eventually lost of function. So early coverage is key to success and rehabilitation. Objective: The assessement of results of treament of postrerior tibial artery perforator flap in covering the lower leg and ankle tissue defect (KHPM). Subjects and methods: 35 patients with tissue defects accompanied by tibia and ankle tendon are treated at the Department of Plastic Surgery, Orthopedic Trauma Hospital - Ho Chi Minh City, From January 2018 - December 2023. The tibial artery ferforater flap is used in covering the limb and ankle soft defects. Using Doppler ultrasound determine the posterior tibial transarterial branch based on the path that connects the point between the popliteal fold and the inner ankle. Result: 31 cases were completely alive, 1 case was completely necrotic, 2 cases were sutured skin, and 1 case was grafted skin. Conclusion: The tibial artery ferforater flap is highly reliable, selectable and flexible in flap design. Good coverage results, shortening treatment time.
