The medial epicondyle is the most medial structure of the humerus. The trochlea is the second.
Medial Epicondlye
Medial epicondyle of humerus and ulna <3
Any explanation always starts with the body in anatomical position. The hands/forearms are supine (palm facing up like you're holding a cup of soup). This would make the pinky (and ulnar bone) medial with the thumb (and radius bone) lateral. At the elbow joint there is a lateral and medial epicondyle (a projection of the humerus where the forearm extensor and flexor muscles attach respectively). For lateral and medial positions this only really affects the forearm/hand since everything else is straightforward.
Lateral epicondyle of the humerus.
The medial epicondyle (on the humerus) is located closet to the body when in the anatomical position and the trochlea (on the humerus) is located slightly laterally and inferior to the medial epicondyle.
I think you are asking about the medial epicondyle not the medical epicondyle. The medial epicondyle is a small bony bump on the end of the humerus kind of making the elbow joint
Swelling at the Medial Epicondyle
An avulsion fracture is when you pull a ligament or tendon from a bone and a piece of that bone comes with it. It is not actually a "fracture". A fracture is a break.

They control the elbow.
The trochlea is the medial process of the humerus. The humerus articulates with the ulna at the trochlea.

fracture involving the presence of an isolated bone fragment. This is also frequently called an avulsion fracture.
