  2. Radial collateral ligament of elbow joint - Wikipedia

    en.wikipedia.org/wiki/Radial_collateral_ligament...

    The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...

  3. Trochlea of humerus - Wikipedia

    en.wikipedia.org/wiki/Trochlea_of_humerus

    During elbow flexion, the vertical anterior part of the trochlea keeps the upper arm and forearm aligned (when viewed in front). During elbow extension, however, the oblique posterior part makes contact with the trochlear notch on the ulna so that this obliquity forces the main axis of the forearm to form a small angle with that of the upper arm.

  4. Fat pad sign - Wikipedia

    en.wikipedia.org/wiki/Fat_pad_sign

    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.

  5. Cubital fossa - Wikipedia

    en.wikipedia.org/wiki/Cubital_fossa

    The cubital fossa, antecubital fossa, chelidon, or inside of elbow is the area on the anterior side of the upper part between the arm and forearm of a human or other hominid animals. It lies anteriorly to the elbow (antecubital) (Latin cubitus) when in standard anatomical position. The cubital fossa is a triangular area having three borders. [1]

  6. Elbow - Wikipedia

    en.wikipedia.org/wiki/Elbow

    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 .

  7. Supracondylar humerus fracture - Wikipedia

    en.wikipedia.org/wiki/Supracondylar_humerus_fracture

    It is more often occurs in males, accounting of 16% of all pediatric fractures and 60% of all paediatric elbow fractures. The mechanism of injury is most commonly due to fall on an outstretch hand. [3] Extension type of injury (70% of all elbow fractures) is more common than the flexion type of injury (1% to 11% of all elbow injuries). [4]

  8. Mobile wad - Wikipedia

    en.wikipedia.org/wiki/Mobile_wad

    These three muscles act as flexors at the elbow joint. [5] The extensor carpi radialis brevis and longus are both weak flexors at the elbow joint. Brevis moves the arm from ulnar abduction to its mid-position and flexes dorsally. Longus is a weak pronator in the flexed arm and a supinator in the outstretched arm.

  9. Osborne's ligament - Wikipedia

    en.wikipedia.org/wiki/Osborne's_ligament

    Osborne's ligament, also Osborne's band, Osborne's fascia, Osborne's arcade, arcuate ligament of Osborne, or the cubital tunnel retinaculum, refers to either the connective tissue which spans the humeral and ulnar heads of the flexor carpi ulnaris (FCU) or another distinct tissue located between the olecranon process of the ulna and the medial epicondyle of the humerus.
