Abstract
Objective: To observe the effects of sural nerve nutrition vessels-supported flap for reconstruction of distal lower leg and ankle soft tissue defects. Methods: From June 2014 to June 2017, 37 patients with calf distal and ankle soft tissue defect were repaired with sural nerve nutrition vessels-supported flap, of them 12 cases with calf distal soft tissue defect wounds and 25 cases with ankle soft tissue defect wounds.The scope of flaps was 9 cm×4 cm to 18 cm×9 cm, anti-infection, anti-freezing and dressing treatments were carried out after operation.The results of two-point discrimination among reexamination were recorded. Results: All the flaps survived without ulcer and effusion, only 1 flap for reconstruction of medial malleolus swelled and deactivated at the beginning while it recovered with proper dressings.During the follow-up periods, all the flaps kept favorable feelings, aspects and functions, and the two-point discrimination was 5 to 15 mm [averaged (11.2±1.7) mm]. Conclusion: Sural nerve nutrition vessels-supported flap brings significant effects with excellent safety and reliability in repairing calf and ankle soft tissue defects.
