摘要
目的 探讨拇外翻合并第2趾锤状趾的原因,为临床预防和治疗提供理论依据.方法 测量121例（167足）拇外翻合并或不合并第2趾锤状趾患者（均为女性,年龄40～83岁）的负重位X线片,将其分为拇外翻组（51例,76足）,半脱位组（47例,68足）,脱位组（23例,23足）.将3组的拇外翻角（HVA）,1、2跖骨间角（M1M2）,1、5跖骨间角（M1M5）,2、5跖骨间角（M2M5）、第2跖骨的突出度（M2.1）、拇外翻角与1、2跖骨间角的差值（HVA-M1M2）,应用单因素方差分析进行统计学分析.结果 拇外翻组、半脱位组、脱位组的HVA分别为（31.0±7.7）°、（38.5±9.7）°、（44.2±6.0）°,M1M2分别为（12.4±2.5）°、（13.6±2.9）°、（15.4 4±4）°,HVA-M1M2分别为（18.6±6.5）.、（24.9±8.9）°、（28.8±5.5）°,各指标的总体检验差异均有统计学意义（P〈0.01）,同时经post hoe（KSD）统计检验,发现各组间也有统计学差异.3组的M1M5、M2M5、M2-1各指标的总体差异均无统计学意义（P〉0.05）.结论 拇外翻伴发第2趾锤状趾的主要原因是由于拇外翻角渐进增大,拇趾对第2趾向外挤压的应力逐渐增大,最终形成第2趾锤状趾.
Objective To analyze the radiographic films of hallux valgus to find out the etiology of hammertoe deformity in the second toe,furthermore,to prevent and treat this deformity clinically.Methods According to the 2nd metatarsophalangeal joint congruence in weight-bearing radiographics,121 halhx valgus patients（167 feet） were divided into three groups：hal]ux valgus group（51 patients,76 feet）,subluxation group（47 patients,68 feet）and dislocated group（23 patients,23 feet）.The hallux valgus angle（HVA）,interfirst and second metatarsal angle （M1M2）,inter first and fifth metatarsal angle（M1M5）,inter second and fifth metatarsal angle（M2M5）,protrude degree of$econd metatarsal（M2-1）,divergence HVA and M1M2（HVA-M1M2）were recorded and analyzed statieally in One-way ANOVA.Results HVA record in Hallux valgus group,subluxation group and dislocated group were（31.0±7.7）°,（38.5±-9.7）°,（44.2±6.0）°respectively.M1M2 in 3 groups were （12.4±2.5）°,（13.6±2.9）°,（15.4 ±3.4）°.HVA-M1M2 in 3 groups was（12.4±2.5）°,（13.6±2.9）°,（15.4 ±3.4）°.Post hoc（LSD）test wag significant among HVA.M1M2,HVA-M1M2.There were no significant differences among M1M5,M2M5,M2-1（P〉0.05）.Conclusions Hammer-toe deformity of the second toe in hallux valgus patients is correlated with the severity of HVA.When the hallux abducts.it pushes second toe laterally and gradually the second hammer-toe deformity are formed.
