Calcaneocuboid malalignment in clubfoot.

Abstract

In a series of 179 clubfeet treated surgically with a follow-up of 3 to 14 years, the clinical significance of calcaneocuboid malalignment was assessed on the basis of a standardized anteroposterior radiograph. The revision rate was 15% and the clinical requirement for a further soft tissue release was related to the talocalcaneal and calcaneocuboid angles. Calcaneocuboid malalignment does not have an adverse effect on the good prognosis of an otherwise well-corrected foot and does not alter the surgery needed to improve a clearly uncorrected foot. When talocalcaneal correction is doubtful, calcaneocuboid malalignment should tilt the balance toward a revision and is of value when the navicular has yet to ossify. Surgical release of the calcaneocuboid joint is unnecessary, particularly the lateral dissection, provided that the medial and subtalar dissection is complete.
