The clinical photograph and radiograph demonstrate hallux valgus with a large first intermetatarsal angle. Metatarsus primus varus and hypermobility of the first ray are both indications for including metatarsocuneiform arthrodesis in the surgical correction of hallux valgus. Anatomic plantarflexion of the first metatarsal is crucial to prevent loading of the lesser metatarsals following surgery. Myerson et al reports the results of 53 patients treated with metatarsocuneiform arthrodesis for hallux valgus and metatarsus primus varus. They found that 92% acheived clinical satisfaction despite numerous complications including 7 superficial pin tract infections, 3 dorsal bunions, 7 nonunions, 1 hallux varus, and 3 neuromas of the deep peroneal nerve. Only 1 of the complications needed secondary surgery. Sangeorzan et al reports the results of metatarsocuneiform arthrodesis in 33 patients with hallux valgus and a hypermobile first ray and 7 patients with previous failed bunion surgery. Successful union occurred in 90%, and 75% were considered successful clinical results. Best results were achieved with bone grafting, multiple screw fixation, and accurate plantarflexion of the first metatarsal. Incorrect Answers: 1,2,4,5: These are all associated with improved clinical outcomes.
