Humerotrochlear Angle
Summary:
- The humerotrochlear angle is one of several radiographic lines used in the evaluation of a supracondylar fracture on a lateral radiograph of the elbow.
- It should be about 40 degrees.

- Drawing a line down the midshaft of the humerus
- Drawing a line along the axis of the condyles
- The angle is between the humeral shaft line and the axis of the condyles and should be ~40 degrees.

How to Measure
While looking at a lateral elbow radiograph (x-ray), the humerotrochlear angle is measured by:
Clinical Application
The humerortrochlear anlge is used in conjunction with other radiographic lines used in assessing for the presence of a supracondylar fracture (a fracture involving the distal end of the humerus):
