Abstract：Objective To investigate the therapeutic effect of TiNi memory alloy suture fractional stretching combined with vacuum sealing drainage(VSD)in repairing chronic lower limb skin defect wounds.Methods Clinical data of 30 patients with chronic full-layer skin defect wounds of lower limbs treated in the Fifth Affiliated Hospital of Guangzhou Medical University from June 2019 to December 2022 were retrospectively analyzed.TiNi memory alloy suture fractional traction combined with VSD was used to repair the defect wounds(the defect area,1.5 cm×2.0 cm to 3.0 cm×13.0 cm).Postoperative wound healing was observed,and the complications and follow-up results were recorded.Results Average of hospital stay was 16.8 d(8 to 35 d).Wound healing was good in all patients,with healing time of 19 to 31 d(average,24.5 d).Good appearance was also found in 30 cases.No wound dehiscence or infection was found at postoperation and during the follow-up.Conclusion Being a simple and convenient surgical procedure,TINi memory alloy suture fractional stretching combined with VSD is effective in the treatment of chronic wounds of small full-layer skin defects of lower limbs which cannot be sutured in the first stage,and has the advantages of short healing time and good appearance.
