The oblique cord is a ligament between the ulnar and radius bones in the forearm near the elbow.It takes the form of a small, flattened band, extending distally and laterally, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity.

Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation. The image acquisition is generally performed by radiographers , and the images are often examined by radiologists .
Awareness of normal anatomic features is crucial for the interpreter to be able to detect subtle signs of fracture. Fat pads should be carefully examined for convexity, which implies joint effusion (e.g., in the hip and elbow). However, the radiographic technique (positioning in particular) must be optimal for this evaluation to be valid.
The interosseous membrane is composed of 5 ligaments:- Central band (key portion to be reconstructed in case of injury)- Accessory band- Distal oblique bundle- Proximal oblique cord- Dorsal oblique accessory cord. Severe forearm injuries involving separation of the radius and ulna may be due to rupture of the interosseous membrane.
The ulna forms part of the wrist joint and elbow joints. Specifically, the ulna joins (articulates) with: trochlea of the humerus, at the right side elbow as a hinge joint with semilunar trochlear notch of the ulna. the radius, near the elbow as a pivot joint, this allows the radius to cross over the ulna in pronation.
X-ray of the forearm (AP and lateral) should also be obtained for because of the common association of supracondylar fractures with the fractures of the forearm. Ideally, splintage should be used to immobilise the elbow at 20 to 30 degrees flexion in order to prevent further injury of the blood vessels and nerves while doing X-rays. Splinting ...
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
Waters' view (also known as the occipitomental view or parietoacanthial projection) is a radiographic view of the skull. It is commonly used to get a better view of the maxillary sinuses. An x-ray beam is angled at 45° to the orbitomeatal line. The rays pass from behind the head and are perpendicular to the radiographic plate.
