The trochlea is an important landmark of the humerus because it is the articulating surface for the humerus of the humeroulnar joint that articulates with the trochlear notch of the ulna. This is a hinge joint allowing for flexion/extension. Some refer to the trochlea as the medial condyle. Dr. J recommends that you call it the trochlea as it articulates with the trochlear notch, which makes it a Grant thing.
