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.
A fat pad sign is an elevation of the anterior and posterior fat pads of the elbow joint, and suggests the presence of an occult fracture. Buccal fat pad can be seen in nursing babies. [1] The fat pad of the labia majora, which can be used as a graft, often as a so-called "Martius labial fat pad graft", which can be used, for example, in ...
The elbow joint has three different portions surrounded by a common joint capsule. These are joints between the three bones of the elbow, the humerus of the upper arm, and the radius and the ulna of the forearm. Is a simple hinge-joint, and allows for movements of flexion and extension only.
On lateral view of the elbow, there are five radiological features should be looked for: tear drop sign, anterior humeral line, coronoid line, fish-tail sign, and fat pad sign/sail sign (anterior and posterior). [3] [8] Tear drop sign - Tear drop sign is seen on a normal radiograph, but is disturbed in supracondylar fracture. [8]
The radius is a long bone, prism -shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
Radial head fractures are diagnosed from a clinical assessment and diagnostic imaging. Clinical assessment may include pain or tenderness at the radial head, bruising, swelling, and a limited range of motion of the injured elbow. [2] Diagnostic imaging may include ultrasound, plain radiography (x-ray imaging), Computed tomography scan (CT), and ...
Olecranon. The olecranon (/ oʊˈlɛkrənɒn /, from Greek olene 'elbow' and kranon 'head'), is a large, thick, curved bony process on the proximal, posterior end of the ulna. It forms the protruding part of the elbow and is opposite to the cubital fossa or elbow pit (trochlear notch). The olecranon serves as a lever for the extensor muscles ...
Cross-section through the middle of the forearm. (Muscles of mobile wad visible at center left.) The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1] It is also sometimes known as the "wad of three", [2] "lateral compartment", [3] or "radial group" [4] of the forearm.
