Abstract：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.
