The olecranon (/ oʊ ˈ l ɛ k r ə n ɒ n /, 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 ).
Olecranon fractures are rare in children, constituting only 5 to 7% of all elbow fractures. This is because in early life, olecranon is thick, short and much stronger than the lower extremity of the humerus. [5] However, olecranon fractures are a common injury in adults. This is partly due to its exposed position on the point of the elbow.
Elbow fractures are any broken bone in or near the elbow joint and include olecranon fractures, supracondylar humerus fractures and radial head fractures. [1] The elbow joint is formed by three different bones: the ulna, radius, and humerus that permit the joint to move like a hinge and allow a person to straighten and bend their arm and these bones are connected by tendons, ligaments, and ...
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 elbow joint is a hinge joint between the arm and the forearm ; [ 2 ] more specifically between the humerus in the upper arm and the radius and ulna in the ...
Size compared to a human. Huaxiazhoulong is a large ankylosaurid, with an estimated body length of 6 metres (20 ft). The holotype specimen likely represents a mature individual, as evidenced by the fusion of the neural arches to the vertebral centrum, the co-ossified scapula and coracoid, high olecranon process of the ulna, and proximal fusion of the anterior and greater trochanters on the femur.
Olecranon bursitis is a condition characterized by swelling, redness, and pain at the tip of the elbow. [ 1 ] [ 2 ] If the underlying cause is due to an infection , fever may be present. [ 2 ] The condition is relatively common and is one of the most frequent types of bursitis .
The olecranon fossa is a deep triangular depression on the posterior side of the humerus, superior to the trochlea. It provides space for the olecranon of the ulna during extension of the forearm .
The Hume fracture is an injury of the elbow comprising a fracture of the olecranon with an associated anterior dislocation of the radial head which occurs in children.It was originally described as an undisplaced olecranon fracture, [1] but more recently includes displaced fractures and can be considered a variant of the Monteggia fracture.
