What is the distal humerus?

Distal humerus refers to a part of Humer's bone in the upper arm, which is furthest from the tribe of the body and closest to the elbow joint. The term relative placement, "distal" is used in anatomy in opposition to the term "proximal". Thus, the distal humerus is far away or the lower end of the bone, while the proximal humerus is the end closest to the shoulder. This part of the bone, also known as the lower limb of the humerus, has the two most important features: lateral and media epicondyles. Epicondyles are two known rounded bony pardonings on both sides of the bottom of the bone, with a side towards the outside of the arm and the center on the inside of the arm closest to the fuselage. As prominent of them, the media epicondyle can be felt just above and on the front sideline and serves as a point of origin for the muscles of the pronator teres in the forearm, as well as for the normal tendon of several forearm bending muscles. On the contrary, the lateral epicondyle is on the opposite side of the elbow and is a point of connection for tendons of supinator muscle and some muscles of the extensor beforeelbow.

Between and slightly below the epicondyles on the distal humerus are the joint surfaces of the bone, which are places where humerus forms joints with ulna and radius bones in the forearms. The side or farthest of them is the chapter that is on the front or front of the humerus and whose rounded surface is articulated with the cavity on the bones of the radius. Another joint surface, this little depression found just above the chapter, is called a radial fossa, which connects to the radius when the elbow is bent.

Medial to the chapter is a trochlea, a cavity found on the front, lower and rear surfaces of the bottom of the distal humerus. This is where the semilunar notch of the ulna, the inside of the large curved structure that resembles the key, wings around the humerus base to form the elbow joint. Above the trochlea on the front and back of the humerus are fossae, cavities on both sides that receive dependent eminence ulna during flexion and extendelbow. During flexion, the coronoid process on the front of the ulna is pushed into a minor depression on the front of the humer known as the coronoid fossa. Similarly, during the elbow extension, a larger triangular depression on the back of the distal humer, known as Olecranon Fossa, is a large olecranon process of the ulna, dirty projection felt on the elbow joint.
