Purpose[edit | edit source]

The Coleman Block Test which Sherman Coleman, MD, and William Chestnut, MD first described in 1977 is used on patients with a Cavo varus foot deformity to determine whether the hindfoot varus deformity is fixed or flexible.

It helps to determine the type of orthotics and surgical management is required.[1]

Technique[edit | edit source]

Positioning-The foot is placed on a block high enough to avoid touching the ground when placing the plantar-flexed first metatarsal over the block’s edge. The medial metatarsals are put off the edge while the rest of the foot remains on the block. This way, the plantar-flexed first metatarsal cannot tilt the foot into the varus.

Result- If the heel deformity is correct while weight bearing during this manoeuvre, the deformity is flexible. If the heel deformity does not correct, there is a fixed hindfoot deformity.[1]


Evidence[edit | edit source]

Level of Evidence - V.

It has been mentioned by experts to use in diagnosing Cavo varus foot in Charcot Marie Disease and the level of evidence is relatively low.
