Abstract

The aim of this study was to associate structural forefoot surgical correction with theories related to the etiology of structural forefoot pathology. All forefoot surgical cases performed at the Inova Fairfax Hospital Ambulatory Surgery Center over a 76-month period (January 2001 through April 2007) were reviewed and classified according to the following surgical categories: hallux abductovalgus, hallux limitus, lesser digital deformity, and combinations of these categories (N = 1684 procedures in 1592 patients). The results suggested that the etiology of lesser digital deformity was associated with the etiology of hallux abductovalgus more so than it was with hallux limitus. In fact, a patient undergoing surgical correction of a hallux abductovalgus deformity displayed 4.63 times greater odds of undergoing surgical correction of a digital deformity, or deformities, compared to a patient undergoing surgical correction of hallux limitus (OR = 4.63, 95% CI 2.81–7.71, P < .0001). Furthermore, medial (second or second and third) toe deformity correction was statistically significantly associated with hallux abductovalgus surgery (OR = 3.34, 95% CI 2.52–4.44, P < .0001), whereas lateral (fifth or fourth and fifth) toe deformity correction was statistically significantly associated with cases that did not involve hallux abductovalgus surgery (OR = 0.27, 95% CI 0.20–0.37, P < .0001). The concept of flexor hallucis longus stabilization is introduced as a possible mechanical explanation for these results. Level of Evidence: 2
