目标：分析跖骨Weil截骨扩大跖骨头间隙对跖间神经炎的疗效； 方法： 选取2015年02月01日至2019年03月31日来本院就诊,且确诊为跖间神经炎(或趾总神经炎)的病人,采用随机的方法分为手术组和对照组,手术组行Weil截骨扩大跖骨头间隙,对照组仅做临床观察,在术前、术后分别确定各足趾麻木范围,将术前和末次随访时足趾麻木范围进行对比。 结果：本次入选病人共31例(共43足),平均年龄为21岁,左足共14例,右足共15例,双足共7例,其中36足为第3、4趾麻木,7足为第2、3趾麻木。手术组和对照组病人均完成随访,随访12-24个月,平均随访时间为18.5个月。手术组共23例,其中治疗有效者20例,其有效率为86.7%；对照组共20例,其中治疗有效者为3例,其有效率15.0%；P值小于0.05,差异有统计学意义。 结论：经Weil截骨扩大跖骨头间距可有效缓解趾总神经卡压引起的神经炎症状,因在研究期间未能收集到Morton神经瘤患者,故无法证实该术式在Morton神经瘤治疗中的有效性。1、

Objectives: To analyze the curative effect of Weil osteotomy of metatarsal bones on metatarsal neuritis；Method: From February 1, 2015 to March 31, 2019, patients with interphalangeal neuritis (or total digital neuritis) were randomly divided into operation group and control group. In operation group, Weil osteotomy was performed to expand the space between metatarsal heads. In control group, only clinical observation was performed. The numbness range of toes was determined during the pre operation and post operation follow-up respectively, and the numbness range of toes at the last follow-up was compared with the pre operation .Results: 31 patients (43 feet) with an average age of 21 years were enrolled in this study, including 14 left feet, 15 right feet, 7 double feet, 36 third and fourth toes, 7 second and third toes. Patients were followed up for 12-24 months in both groups, and the average is 18.5 months.There were 23 cases in operation group, 20 cases’ treatment of them is effective, the rate of effective was 86.7%; There were 20 cases in control group, 3 cases’ treatment is effective , the rate of effective was 15.0%; P value was less than 0.05, the difference was statistically significant.Conclusion: Weil osteotomy can effectively relieve the neuritis caused by the compression of the total toe nerve, because Morton neuroma patients were not collected during the study period, it can not confirm the effectiveness of the operation in the treatment of Morton neuroma.
