  3. Ulna fracture - Wikipedia

    en.wikipedia.org/wiki/Ulna_fracture

    An ulna fracture is a break in the ulna bone, one of the two bones in the forearm. [2] It is often associated with a fracture of the other forearm bone, the radius. [1] [3]An ulna fracture can be a single break as in a so called nightstick fracture, which can be caused by someone being hit on the inside of the forearm often by a stick, notably when they are holding their arm up to protect ...

  4. Ulna - Wikipedia

    en.wikipedia.org/wiki/Ulna

    Near the elbow, the ulna has two curved processes, the olecranon and the coronoid process; and two concave, articular cavities, the semilunar and radial notches. [ 4 ] The olecranon is a large, thick, curved eminence, situated at the upper and back part of the ulna.

  5. Elbow fracture - Wikipedia

    en.wikipedia.org/wiki/Elbow_fracture

    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 ...

    Between these two bands a few intermediate fibers descend from the medial epicondyle to blend with a transverse band which bridges across the notch between the olecranon and the coronoid process. This ligament is in relation with the triceps brachii and flexor carpi ulnaris and the ulnar nerve , and gives origin to part of the flexor digitorum ...

    en.wikipedia.org/wiki/Trochlear_notch

    The trochlear notch (/ ˈ t r ɒ k l ɪər /), [1] also known as semilunar notch and greater sigmoid cavity, is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint. It is formed by the olecranon and the coronoid process.

  8. Supracondylar humerus fracture - Wikipedia

    Bleeding from the fracture expands the joint capsule and is visualized on the lateral view as a darker area anteriorly and posteriorly, and is known as the sail sign. [8] Coronoid line - A line drawn along the anterior border of the coronoid process of the ulna should touch the anterior part of the lateral condyle of the humerus. If lateral ...

  9. Tuberosity of the ulna - Wikipedia

    en.wikipedia.org/wiki/Tuberosity_of_the_ulna

    The tuberosity of the ulna is a rough eminence on the proximal end of the ulna. It occurs at the junction of the antero-inferior surface of the coronoid process with the front of the body. It provides an insertion point to a tendon of the brachialis [1] [2] (the oblique cord of the brachialis is attached to the lateral border).
