Foot size asymmetry following Ponseti treatment versus comprehensive surgical releases for unilateral clubfeet.

Using age and height matched cohorts with unilateral idiopathic clubfeet (n=40 each), we retrospectively reviewed pedobarographic studies to determine the impact of treatment, Ponseti versus comprehensive surgical releases (CSR), on the foot length, width, and contact area. The foot pressures were determined by self-selected walking across a force plate. Ponseti treatment results in more symmetrical foot lengths, widths, and total contact areas with an improvement of 1.3 shoe sizes difference compared with treatment with CSR. This suggests that there is improved growth in the clubfoot in those treated with Ponseti management compared with those treated with CSR.
