  2. Axillary nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Axillary_nerve_palsy

    An injury to the axillary nerve normally occurs from a direct impact of some sort to the outer arm, though it can result from injuring a shoulder via dislocation or compression of the nerve. The axillary nerve comes from the posterior cord of the brachial plexus at the coracoid process and provides the motor function to the deltoid and teres ...

  3. Axillary nerve dysfunction - Wikipedia

    en.wikipedia.org/wiki/Axillary_nerve_dysfunction

    Axillary nerve dysfunction is any disorder caused by damage to the axillary nerve. [1] The axillary nerve is a branch of the brachial plexus that innervates the deltoid and teres minor muscles. This nerve can be injured or damaged in a variety of ways - penetrating injury such as knife or gunshot wounds, surgical trauma, stretch injury (common ...

  4. Brachial plexus block - Wikipedia

    en.wikipedia.org/wiki/Brachial_plexus_block

    The axillary block is also the safest of the four main approaches to the brachial plexus, as it does not risk paresis of the phrenic nerve, nor does it have the potential to cause pneumothorax. [12] In the axilla, the nerves of the brachial plexus and the axillary artery are enclosed together in a fibrous sheath which is a continuation of the ...

  5. Shoulder injury related to vaccine administration - Wikipedia

    en.wikipedia.org/wiki/Shoulder_injury_related_to...

    SIRVA is caused by improper insertion of the needle used in injections. It is "a preventable occurrence caused by the injection of a vaccine into the shoulder capsule rather than the deltoid muscle. As a result, inflammation of the shoulder structures causes patients to experience pain, a decreased range of motion, and a decreased quality of life."

  6. Injury of axillary nerve - Wikipedia

    en.wikipedia.org/wiki/Injury_of_axillary_nerve

    Injury of axillary nerve (axillary neuropathy) is a condition that can be associated with a surgical neck of the humerus fracture. It can also be associated with a dislocated shoulder [ 1 ] or with traction injury to the nerve, which may be caused by over-aggressive stretching or blunt trauma that does not result in fracture or dislocation. [ 2 ]

  7. Deltoid muscle - Wikipedia

    en.wikipedia.org/wiki/Deltoid_muscle

    Site of the intramuscular injection in deltoid: The intramuscular injections are commonly given in the lower half of the deltoid to avoid injury to the axillary nerve, which [15] winds around the surgical neck of the humerus.

  8. Axillary nerve - Wikipedia

    en.wikipedia.org/wiki/Axillary_nerve

    The nerve lies at first behind the axillary artery, [4] and in front of the subscapularis, [1] and passes downward to the lower border of that muscle.. It then winds from anterior to posterior around the neck of the humerus, in company with the posterior humeral circumflex artery, [2] through the quadrangular space (bounded above by the teres minor, below by the teres major, medially by the ...

  9. Intramuscular injection - Wikipedia

    en.wikipedia.org/wiki/Intramuscular_injection

    The most frequent complications of a deltoid injection include pain, redness, and inflammation around the injection site, which are almost always mild and last only a few days at most. [ 11 ] The dorsogluteal site of injection is associated with a higher risk of skin and tissue trauma, muscle fibrosis or contracture , hematoma , nerve palsy ...
