The current literature shows that proper alignment of the lower extremity allows for greater function throughout the gait cycle. Therefore, realignment should be one of the primary goals in the surgical management of lower-extremity deformities and pathology. Multiplanar radiographic angular relationships should be critically evaluated to appropriately identify the level and extent of the deformity before performing realignment procedures. This article describes a systematic approach to deformity evaluation through a comprehensive radiographic assessment of the rearfoot, ankle, and lower leg.
