BACKGROUND: The aim of this study was to determine whether excessive medial deviation of the first metatarsal (excessive intermetatarsal angle) is present in the initial phase of hallux valgus. METHODS: The intermetatarsal angle between the first and second metatarsals (1-2 IMA) was radiographically studied in 49 normal feet and in 49 feet with mild hallux valgus deformity. RESULTS: The results demonstrated a statistically significant difference in the mean intermetatarsal angle between the two groups (8.76 degrees in normal feet; 9.98 degrees in affected feet). However, we believe that is not clinically significant. Other authors, comparing the 1-2 IMA in patients with or without more advanced hallux valgus, reported greater differences than those obtained in this study. CONCLUSIONS: Excessive medial deviation of the first metatarsal is not a causal factor but rather a consequence of hallux valgus deformity.
