研究目的:

1.主要目的:探讨TTT干预组(创面清创+胫骨横向骨搬移术)治疗TexasⅡ~Ⅲ级糖尿病足是否比对照组(创面清创+标准负压封闭引流+二期植皮治疗)具有更高的1年保肢率。 2.次要目的:评估胫骨横向骨搬移技术治疗TexasⅡ~Ⅲ级糖尿病足是否比VSD结合二期植皮方法的临床效果(6个月溃疡愈合率;溃疡愈合时间;1年溃疡复发率;CT血管造影评估下肢微血管变化情况;溃疡足部肌肉血流速率和血流量(CT灌注成像);末梢供血情况;足部VAS评分;足部神经筛查;(AOFAS)踝与后足功能评分量表;实验室检查;生物标志物;不良事件)更好  

Objectives of Study:

1. Main objective: To investigate whether the TTT intervention group (wound debridement + transverse tibial bone transport surgery) has a higher one-year limb salvage rate for the treatment of Texas II-III diabetic foot compared to the control group (wound debridement + standard negative pressure wound therapy + two-stage skin grafting). 2. Secondary objectives: To evaluate the clinical efficacy of transverse tibial bone transport technique in the treatment of Texas II-III diabetic foot compared to VSD combined with two-stage skin grafting method (6-month ulcer healing rate; ulcer healing time; one-year ulcer recurrence rate; assessment of lower limb microvascular changes using CT angiography; ulcer foot muscle blood flow rate and blood flow volume (CT perfusion imaging); peripheral blood supply condition; foot VAS score; foot nerve examination; AOFAS ankle and hindfoot functional score; laboratory tests; biomarkers; adverse events) better.

随机方法(请说明由何人用什么方法产生随机序列):

本试验由不参与临床试验的统计师,在计算机上通过SPSS统计软件采用单纯随机分组的方法生成随机号和分组信息,以1:1比例将受试者随机分入干预组或对照组,产生随机的种子数以及随机结果作为盲底保存。统计师通过网络反馈研究者该研究对象被分入干预组或对照组。研究者接到随机分组结果后,按照相应组别给研究对象进行相应治疗,接受干预组治疗或对照组治疗。

Randomization Procedure (please state who generates the random number sequence and by what method):

This experiment was conducted by a statistician who was not involved in the clinical trial. Using SPSS statistical software on a computer, the statistician used a simple random grouping method to generate random numbers and grouping information. The participants were randomly assigned to the intervention or control group in a 1:1 ratio. The random seed number and random results were kept blind. The statistician provided feedback to the researchers through the internet on which group each participant was assigned to. After receiving the random grouping results, the researchers administered the respective treatments to the participants according to their assigned group, either the intervention or control group.
