A lateral heel wedge is used for which condition?

• A. Excessive pes varus or genu varum
• B. Pes planus
• C. Metarsalgia
• D. Trunk extensor spasms

Answer: (A)

Using a lateral heel wedge changes how the hindfoot is loaded by lifting the outside of the heel. This tends to push the calcaneus toward valgus (eversion), counteracting excessive hindfoot varus and the related bowing seen in genu varum. By encouraging a more neutral or valgus alignment during stance, the wedge redistributes forces laterally and can alleviate symptoms associated with varus conditions like pes varus.

This choice is not aimed at pes planus (flat foot), which typically requires arch support or medial reinforcement to lift and support the medial column. It also won’t address forefoot pain from metarsalgia, which calls for forefoot off-loading strategies such as metatarsal pads or cushioning, nor would it address trunk extensor spasms, which are neurological/muscle control issues unrelated to heel alignment.
