When a foot is placed on a wooden block during the Coleman block test, what should occur with flexible rearfoot varus?

• A. The rearfoot should remain fixed
• B. The forefoot will plantarflex
• C. The rearfoot will evert
• D. The forefoot will remain in varus

Answer: (C)

The Coleman block test is utilized to assess flexible rearfoot varus, specifically by observing the rearfoot's behavior when the forefoot is positioned on an elevated surface, such as a wooden block. During this test, if there is a flexible rearfoot varus present, the rearfoot is expected to evert when the forefoot is allowed to stay in a fixed position on the block. The underlying mechanics involve the position of the subtalar joint and the relationship between the rearfoot and forefoot. By elevating the forefoot, the test removes the impact of forefoot positioning on the rearfoot's alignment. In a flexible rearfoot varus, when the forefoot is supported, the rearfoot compensates by everting, which indicates that the varus condition can be corrected with the proper positioning of the forefoot. In contrast, if the rearfoot were to remain fixed, this would suggest rigidity and a non-flexible condition. Similarly, a plantarflexed forefoot indicates a different set of biomechanical adjustments that do not align with the flexible nature of rearfoot varus. Hence, the expected outcome of eversion during the Coleman block test supports the diagnosis of flexible rearfoot varus.
