What is the normal Boehler's angle range?

• A. 20-40 degrees
• B. 0-20 degrees
• C. 40-60 degrees
• D. 5-15 degrees

Answer: (A)

Boehler's angle on a lateral calcaneal radiograph is an angle formed by the superior contour of the calcaneus and is used to assess the height and integrity of the calcaneus, especially the posterior facet. The normal range is about 20 to 40 degrees, with most people landing in the low-to-mid 30s. When the posterior facet collapses due to a fracture, the angle decreases toward the lower end of this range or below, indicating loss of height. Values far outside this range are not typical in a healthy calcaneus.
