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.
Antero-posterior (AP) and lateral view of the elbow joint should be obtained. Any other sites of pain, deformity, or tenderness should warrant an X-ray for that area too. 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.
The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. [1] The elbow includes prominent landmarks such as the olecranon , the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus .
The joint capsule of the elbow attaches to the humerus just proximal to the olecranon fossa. [3] [4] Function

Studies generally use the x-ray appearance of the arm to determine how displaced a fracture is. The definition of ‘displaced fractures' are variable, with anything from 2mm to more than 15mm; [4] however x-rays on which this assessment is made are known to be hugely misleading with fractures showing little displacement having >10mm displacement using CT scans.
Because intra-articular fractures cause a joint effusion, the dorsal fat pad sign is a reliable parameter for diagnosis of elbow fractures. [17] If a joint effusion is depicted in the ultrasound, two-plane X-ray imagery is necessary to diagnose the fracture. The standard procedure is the elbow-SAFE algorithm. [18]
The humeroulnar joint (ulnohumeral or trochlear joint [1]) is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. [1] It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction.
