Utility of the Coleman block test

Area of Science:

• Orthopedic surgery
• Podiatry
• Pediatric orthopedics

Background:

• The Coleman block test is a crucial part of the foot and ankle physical examination.
• It is used for both pediatric and adult patients.

Purpose of the Study:

• To describe the Coleman block test.
• To summarize its implications in surgical decision-making.
• To discuss its limitations.

Main Methods:

• The test involves placing a block under the lateral foot column to isolate hindfoot alignment.
• It assesses if hindfoot varus corrects to valgus when the plantarflexed first ray is removed.
• Modifications include radiographic assessment and adaptations for children.

Main Results:

• The test differentiates flexible cavovarus deformities (requiring only cavus correction) from rigid ones (needing additional calcaneal osteotomy).
• Flexible deformities indicate that only the cavus component requires surgical correction.
• Rigid deformities necessitate further surgical intervention, such as a lateral displacement osteotomy of the posterior calcaneus.

Conclusions:

• The Coleman block test is a straightforward clinical evaluation.
• It should be routinely performed when assessing cavovarus deformities.
• It aids in developing the most appropriate surgical plan.
