Distal Humerus AP Acute flexion view.

Also known as tangential view, inferior-to-superior projection, or Jones view.

It is indicated in fractures and moderate dislocations of the elbow in acute flexion; and allows to see the olecranon, ulnar groove, trochlea, and radial head.

It is also useful for detecting intra-articular loose bodies and degenerative osteophytes in the olecranon-trochlear joint compartment.

To perform it, patient is seated alongside the radiographic table with acutely flexed elbow. (unless contraindicated). The central ray is perpendicular to the humerus, approximately 5 cm above to the olecranon process.

Evalutation Criteria: The following should be clearly shown:

• Forearm and humerus should be superimposed
• No rotation
• Olecranon process and distal humerus
• Soft tissue outside the olecranon process and bony trabecular detail
