Comprehension: X-Rays of Elbow
Study frontal and lateral radiographs of the elbow. Identify the capitulum, the trochlea, the coronoid and olecranon fossae, as well as the medial epicondyle. The lateral epicondyle is not as prominent as its medial counterpart. Note the olecranon, trochlear notch, and coronoid process of the ulna. Identify the head, neck and radial tuberosity on the radius. In the lateral film, the radial tuberosity is pointing anteriorly (up in the radiograph). How might one determine if the hand was supinated or pronated in a radiograph of the elbow?
Arterial and Venous Anatomy- Elbow Joint
Arterial and venous anatomy at the elbow joint are shown in digital subtraction studies. The digital subtraction arteriogram has been made after injection of contrast material in the subclavian artery. Note the prominent collateral circulation about the elbow. The superficial veins of the elbow are well delineated with the subtraction technique after injection of contrast material in a hand vein. There is considerable variation in the anatomy of the veins in the antecubital fossa. This patient has a fairly typical arrangement of veins including the position of the median antecubital vein.
