  2. Annular ligament of radius - Wikipedia

    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.

  3. Proximal radioulnar articulation - Wikipedia

    en.wikipedia.org/wiki/Proximal_radioulnar...

    It occurs between the circumference of the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament. [2] The interosseous membrane of the forearm and the annular ligament stabilise the joint. [2] A number of nerves run close to the proximal radioulnar joint, including: median nerve; musculocutaneous nerve ...

  4. Ulnar neuropathy - Wikipedia

    en.wikipedia.org/wiki/Ulnar_neuropathy

    Ulnar neuropathy is a disorder involving the ulnar nerve. Ulnar neuropathy may be caused by entrapment of the ulnar nerve with resultant numbness and tingling. [3] It may also cause weakness or paralysis of the muscles supplied by the nerve. Ulnar neuropathy may affect the elbow as cubital tunnel syndrome.

  5. Flexor retinaculum of the hand - Wikipedia

    en.wikipedia.org/wiki/Flexor_retinaculum_of_the_hand

    The ulnar artery and ulnar nerve, and the cutaneous branches of the median and ulnar nerves, pass on top of the flexor retinaculum. On the radial side of the retinaculum is the tendon of the flexor carpi radialis, which lies in the groove on the greater multangular between the attachments of the ligament to the bone.

  6. Ulnar neuropathy at the elbow - Wikipedia

    en.wikipedia.org/wiki/Ulnar_neuropathy_at_the_elbow

    Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...

  7. Ulnar nerve - Wikipedia

    en.wikipedia.org/wiki/Ulnar_nerve

    The ulnar nerve is a nerve that runs near the ulna, one of the two long bones in the forearm. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest in the human body unprotected by muscle or bone, so injury is common. [ 1 ]

  8. Pulled elbow - Wikipedia

    en.wikipedia.org/wiki/Pulled_elbow

    In this movement the ulna, which is connected to the humerus by a simple hinge-joint, remains stationary, while the radius rotates, carrying the wrist and hand with it. To allow this rotation, the proximal (elbow) end of the radius is held in proximity to the ulna by a ligament known as the annular ligament.

  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.
