Which way does a Dwyer osteotomy slide the calcaneus?

Explanation:
The Dwyer osteotomy is a lateral closing‑wedge procedure of the calcaneus aimed at correcting hindfoot varus by shifting the posterior part of the heel laterally. A wedge is taken out from the lateral aspect of the calcaneus behind the subtalar joint, and when the osteotomy is closed, the posterior fragment slides toward the lateral side. This lateral shift realigns the hindfoot into valgus, which is the corrective goal for varus deformity.
