Objective To investigate the effect of body mass index (BMI) on the healing of limb fractures. Methods 320 patients with open reduction and internal fixation of limb closed fractures between March 2013 and March 2016 were divided into ideal group,overweight group and obese group according to BMI. The body temperature,Line time,antibiotic use time,postoperative hemogram index and incision infection rate and other statistical were studied. Results There were no statistically significant differences in sex,age,fracture type,operation time and operation time among the three groups (P>0.05). There was no significant difference between the ideal group and the other two groups (P>0.05). There was no significant difference between the overweight group and the obese group in blood parameters (P>0.05),and the differences of the other indexes were statistical significance (P<0.05). Conclusions BMI has a certain effect on the healing of incision of closed limb fracture. BMI higher patients, surgical incision healing more slowly and the higher the infection rate.%目的 探讨患者体重指数(BMI)对四肢骨折手术切口愈合情况的影响.方法 选取2013年3月至2016年3月行四肢闭合骨折切开复位内固定术的患者共320例,根据患者BMI分为理想组、超重组、肥胖组,对三组患者术后体温、拆线时间、抗生素使用时间、术后血象指标及切口感染率等情况进行统计研究.结果 三组患者在性别、年龄、骨折类型及手术方式、手术时间等一般情况上的差异均无统计学意义(P>0.05).在各个指标上理想组与其他两组比较,差异均有统计学意义(P<0.05),超重组与肥胖组在术后血象指标上差异无统计学意义(P>0.05),其余指标差异均有统计学意义(P<0.05).结论 体重指数对四肢闭合骨折手术切口的愈合有一定的影响,BMI越高的患者,手术切口愈合越慢,感染率越高.
