Final answer:
Bohler's angle is a measurement used in radiology to assess calcaneus fractures. An abnormal Bohler's angle can indicate various types of fractures.
Step-by-step explanation:
Bohler's angle is a measurement used in radiology to assess the severity of a fracture in the calcaneus bone, which is located in the heel. It is measured by drawing two lines on an X-ray to determine the angle formed by the lines.
The normal Bohler's angle range is between 20 and 40 degrees. An abnormal Bohler's angle can indicate a fracture or injury to the calcaneus bone.
If the angle is below the normal range, it may suggest a displaced or comminuted fracture. If the angle is above the normal range, it may indicate more subtle forms of fracture or a stress fracture.
