Several factors associated with metatarsalgia in patients with hallux valgus

TORONTO — Achilles shortening, excessive weight and associated lesser toe deformity were associated with metatarsalgia among patients with hallux valgus, according to results presented at the American Orthopaedic Foot & Ankle Society Annual Meeting.

“Our findings question the assumption that both the magnitude of hallux valgus deformity and an increased length of the lesser metatarsal by themselves act as etiologic factors,” Gaston Slullitel, MD, said in his presentation. “Metatarsalgia was associated with gastro-shortening and excessive weight and associated lesser toe deformities, so these factors should be addressed in order to treat this disorder adequately.”

Slullitel and colleagues analyzed 121 patients (184 feet) with non-arthritic hallux valgus and categorized patients into two groups: those with metatarsalgia; and those without the condition.

According to results, 45.6% of feet had metatarsalgia. Slullitel noted a correlation between increased weight, gastrocnemius shortening, lesser toe deformities and metatarsal index. He added the metatarsal index had an inverse statistical relationship in which metatarsal pain was less likely among index minus patients.

“The main outcome was that we did not observe a statistical relationship between the magnitude of hallux valgus and the occurrence of metatarsalgia, and the same happened with the metatarsal index,” Slullitel said. – by Casey Tingle
