Objective To evaluate the physiological function and the anatomic structure of the first metatarsophalangeal joint for the patient withhallux valgus after a remodeling operation with the Keller’s method. Methods From April 2004 to November 2006, the first metatarsophalangeal joints in 11 patients (22 feet) with hallux valgus were remodeled with the Keller’s operation. There were 3 males and 8 females, aged 5173 years. Accordingto the Piggot typing standard, there were 17 feet of type Ⅱ (deflexion) and 5 feet of type Ⅲ (semiluxation). The hallux valgus angles(HVAs) were 2449° (average, 37°). The intermetatarsal angles (IMAs) were 90135° (average, 115°). The curative effect and the anatomic structure were evaluated by the followup and the Xray examination. Results All the cases werefollowed up for 6 to 30 months after operation (average, 14 months). According to the standard of ZHU Li Hua, et al, the results were excellent in 18 feet,good in 3 feet, and poor in 1 foot. The Xray films showed that the first meta tarsophalangeal joint of 14 feet developed mortarlike false articulation, and 8 feet developed partial false articulation. HVAs were 716° (average, 11°).IMAs were 90135° (average, 11.5°). According to the Piggot typing standard, there were 12 feet of typeⅠ(fitter) and 10 feet of type Ⅱ (deflexion). Conclusion For the patients with hallux valgus, the remodeling ofthe first metatarsophalangeal joint by the Keller’s operation can rectify HVA, improve the stability of the joints, and prevent occurrence of the insufficient muscle strength after operation.
