What causes the carrying angle of the elbow joint? What functional purpose does the carrying angle serve?

Question

Quizplus · Accepted Answer

The Answer is The carrying angle is created by the obliquity of the humeral condyles and elbow joint axis.Although the elbow is a hinge joint,the axis is tilted slightly (down on the medial side).Thus,as the elbow flexes,the forearm moves medially on the humerus (like folding a piece of paper on a crooked fold).The effect is that elbow flexion brings the hand closer to the mouth (a very functional movement)without any glenohumeral rotation.
