A 12-year-old boy presented with bilateral flexible flatfoot characterised by talar plantarflexion, talonavicular uncoverage and loss of the medial longitudinal arch. The right foot had undergone successful subtalar arthroereisis approximately one year previously. The current procedure addressed the unoperated left foot, permitting direct clinical and radiographic comparison with the corrected contralateral side.

Be the first to ask the faculty about this procedure.

Subtalar arthroereisis can restore talar alignment and medial-arch mechanics in carefully selected flexible flatfoot, but success depends on accurate sinus-tarsi placement and sizing that corrects excessive pronation without eliminating normal subtalar motion.

Key takeaway

Subtalar arthroereisis can restore talar alignment and medial-arch mechanics in carefully selected flexible flatfoot, but success depends on accurate sinus-tarsi placement and sizing that corrects excessive pronation without eliminating normal subtalar motion.
