Abstract:
Objective:To investigate the efficacy of the nutrient vessel of medial and lateral sural subcutaneous nerve chimeric tissue flap based on posterior perforating branch of peroneal artery to repair the composite tissue defect in the Achilles tendon area.Methods:From January 2016 to June 2021, 12 patients suffering from infectious wound with defect of Achilles tendon were treated in the Department of Trauma and Microscopic Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. The area of soft tissue defect around Achilles tendon was 2.5 cm× 4.5 cm-8.0 cm×12.5 cm, and the length of the defect of Achilles tendon was 3.0-7.0 cm. The defect around the Achilles tendon were repaired with the nutrient vessel of medial and lateral sural subcutaneous nerve chimeric Achilles tendon flap (ATF) and the posterior perforating branch of peroneal artery was used as the vessel of blood supply. The size of flap was 3.0 cm×5.0 cm-9.0 cm×13.0 cm, and the size of the ATF was 3.0 cm×4.0 cm-3.0 cm×8.0 cm. The donor sites were sutured directly (8 cases) or repaired with skin graft (4 cases). External fixation were put on for 6 weeks after surgery. Then the external fixation was removed and the functional exercise gradually started. Outpatient clinic follow-ups were carried out regularly. Thermann Achilles tendon function assessment system was used to evaluate the last follow-up.Results:The chimeric ATF was harvested and the blood supply of each flap was good during the operation. There was no vascular crisis after surgery. The flaps survived smoothly and the wound achieved grade A healing. All patients were entered follow-up that lasted for 10-24 months. There was good appearance of flaps with minor bloating, and the colour of flaps was similar to the skin around the receiving site. The texture was soft with normal function of the lower legs and ankle. Tendon function was evaluated by Thermann Achilles tendon function assessment system, the result were 8 cases in excellent and 4 cases in good.Conclusion:The nutrient vessel of medial and lateral sural subcutaneous nerve chimeric tissue flap based on posterior perforating branch of peroneal artery can accurately repair a composite tissue defect in the Achilles tendon area, and it is one of the effective methods for the repair of a composite soft tissue wound with Achilles tendon defect.
