Hallux valgus with second metatarsalgia: Is second metatarsal Weil osteotomy necessary?

ABSTRACT

BACKGROUND: The role of concomitant Weil osteotomy to address second toe metatarsalgia during hallux valgus correction is unclear. We aimed to critically analyse outcomes of an additional Weil osteotomy versus isolated Scarf osteotomy.in the management of hallux valgus and second metatarsalgia. METHODS: Patients with second toe metatarsalgia who underwent first metatarsal Scarf osteotomy for hallux valgus were enrolled retrospectively. Demographics, radiographic measurements and functional outcomes were assessed at baseline, 6-months and 2-years postoperatively. Between-group significance was established with Fisher exact test, Chi-square or Mann-Whitney U test. Within-group changes from baseline were assessed with paired t-test and Wilcoxon signed-rank test. RESULTS: 48 feet (34 isolated Scarf, 14 concomitant Weil osteotomy) were included. Both cohorts demonstrated significant improvements across all measures of functional outcome. However, patients with additional Weil osteotomy reported poorer short-term outcomes. CONCLUSION: Superiority of additional Weil osteotomy versus isolated Scarf osteotomy in addressing second toe metatarsalgia or improving functional outcomes was not demonstrated.
