    Abstract:
    Objective: To investigate the clinical effects of antibiotic bone cement combined with free anterolateral thigh flap in sequential treatment of diabetic foot ulcer (DFU) wounds. Methods: A retrospective observational study was conducted. From August 2018 to August 2021, 15 patients with DFU who met the inclusion criteria were admitted to the Affiliated Hospital of Zunyi Medical University, including 12 males and 3 females, aged 42-65 years, with a history of type 2 diabetes for 5-19 years. All the wounds of patients were complicated with local bone, muscle, or tendon defects or exposure. The wounds were covered with antibiotic bone cement after debridement in stage Ⅰ+free anterolateral thigh chimeric perforator flap (perforator flap+muscle flap) or simple free anterolateral thigh flap grafting in stage Ⅱ. The defect area of the wound after bone cement removal and debridement was 9.0 cm×5.0 cm-20.0 cm×7.0 cm, the incision area of the flap was 10.0 cm×5.0 cm-22.0 cm×7.0 cm, and the incision area of the muscle flap was 5.0 cm×3.0 cm-8.0 cm×4.0 cm. The donor sites of flaps were sutured directly. During follow-up, the situations of donor site healing and flap survival were observed. At the last follow-up, the texture and shape of the flap, the presence of new ulcers on both limbs, and the walking ability of the patient were observed. Results: During the follow-up of 8 to 21 months after operation in stage Ⅱ, the donor sites healed well with only residual linear scar; flaps in 14 patients survived completely, and the flap in 1 patient developed partial necrosis at 3 weeks after stage Ⅱ surgery, which was healed after debridement and skin grafting. At the last follow-up, the flaps were good in texture and appearance, there were no new ulcers in the affected limb or opposite limb, and the patients had no obvious impairment in daily walking function. Conclusions: To repair DFU wounds with antibiotic bone cement combined with free anterolateral thigh flap can rapidly control the infection, achieving a high survival rate of flap after operation with no obvious impairment in daily walking function of patients. 目的： 探讨抗生素骨水泥联合游离股前外侧组织瓣序贯治疗糖尿病足溃疡（DFU）创面的临床疗效。 方法： 采用回顾性观察性研究方法。遵义医科大学附属医院于2018年8月—2021年8月收治15例符合入选标准的DFU患者，其中男12例、女3例，年龄42~65岁，2型糖尿病病史5~19年。患者创面均合并局部骨骼、肌肉或肌腱缺损或外露，创面均于Ⅰ期清创后行抗生素骨水泥覆盖+Ⅱ期游离股前外侧嵌合穿支皮瓣（穿支皮瓣+肌瓣）或单纯游离股前外侧穿支皮瓣移植修复，拆除骨水泥并清创后的创面面积为9.0 cm×5.0 cm~20.0 cm×7.0 cm，皮瓣切取面积为10.0 cm×5.0 cm~22.0 cm×7.0 cm，肌瓣切取面积为5.0 cm×3.0 cm~8.0 cm×4.0 cm。组织瓣供区均直接缝合。随访时观察供区愈合情况、皮瓣成活情况。末次随访时，观察组织瓣质地、外形，双侧肢体有无新发溃疡，患者行走能力。 结果： Ⅱ期术后随访8~21个月，供区均愈合良好，仅残留线性瘢痕；14例患者组织瓣完全成活，1例患者在Ⅱ期术后3周出现皮瓣部分坏死，经扩创+植皮后愈合。末次随访时，组织瓣质地良好、外形佳，患肢及对侧肢体无新发溃疡，患者日常行走功能无明显障碍。 结论： 采用抗生素骨水泥联合游离股前外侧组织瓣修复DFU创面，可快速控制感染，术后皮瓣成活率较高，患者日常行走功能无明显障碍。.
