  2. Pulled elbow - Wikipedia

    en.wikipedia.org/wiki/Pulled_elbow

    A pulled elbow typically results from a sudden pull on an extended arm. [2] This may occur when lifting or swinging a child by the arms. [2] The underlying mechanism involves slippage of the annular ligament off of the head of the radius followed by the ligament getting stuck between the radius and humerus. [1] Diagnosis is often based on ...

    en.wikipedia.org/wiki/Annular_ligament_of_radius

    The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna. [ 1 ] Per Terminologia Anatomica 1998 , the spelling is "anular", [ 2 ] but the spelling "annular" is frequently encountered.

    There is calcification of annular ligament, which can be seen as early as 2 weeks after injury. [29] Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. [30]

  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 ...

    The acute rupture occurs in collisions when the elbow is in flexion such as that in a wrestling match or a tackle in football. The ulnar collateral ligament distributes over fifty percent of the medial support of the elbow. [16] [17] This can result in an UCL injury or a dislocated elbow causing severe damage to the elbow and the radioulnar joints.

  7. Head of radius - Wikipedia

    en.wikipedia.org/wiki/Head_of_radius

    The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament.

    A fracture within the capsule of the elbow joint results in the fat pad sign or "sail sign" which is a displacement of the fat pad at the elbow. Illustration showing radius shaft fracture Essex-Lopresti fracture – a fracture of the radial head with concomitant dislocation of the distal radio-ulnar joint with disruption of the interosseous ...

  9. Radial tunnel syndrome - Wikipedia

    en.wikipedia.org/wiki/Radial_tunnel_syndrome

    The radial nerve provides sensation to the skin of posterior arm, posterior and lateral forearm and wrist, and the joints of the elbow, wrist and hand. The nerve also provides sensory branches that travel to the periosteum of the lateral epicondyle, the anterior radiohumeral joint, and the annular ligament.
