Which statement best describes the Coleman block test's purpose?

• A. To distinguish forefoot-driven cavus from rearfoot-driven cavus
• B. To assess plantar fascia tension
• C. To measure hindfoot valgus angle
• D. To evaluate tibial torsion

Answer: (A)

The Coleman block test is used to determine whether a cavus foot deformity is driven by the forefoot or by the hindfoot. By placing a block under the forefoot so the hindfoot bears most of the weight and the first ray can plantarflex, you’re isolating the forefoot’s influence on hindfoot alignment. If the hindfoot moves toward neutral when the forefoot is unloaded, the deformity is forefoot-driven (a flexible forefoot deformity causing secondary hindfoot varus). If the hindfoot remains in varus despite blocking the forefoot, the hindfoot itself is the primary driver (hindfoot-driven cavus). This distinction guides planning, since forefoot-driven deformities often improve with forefoot correction, while hindfoot-driven deformities may require hindfoot-focused treatment.
