Axillary nerve palsy is characterized by the lack of shoulder abduction greater than 30 degrees with or without the loss of sense in the low two thirds of the shoulder. Normally the patients that have axillary nerve palsy are involved in blunt trauma and have a number of shoulder injuries. Surgery is not always required to solve the problem ...
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 ]
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 ...
As cutaneous nerves cover all areas of the skin, and any surgery which requires incisions may inadvertently cause injury or scarring, now entrapping a cutaneous nerve. [15] A common tradeoff when electing to a neurectomy is that numbness along the nerve distribution is expected.
Symptoms include shoulder pain and instability. [2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve. [1] A shoulder dislocation often occurs as a result of a fall onto an outstretched arm or onto the shoulder. [3] Diagnosis is typically based on symptoms and confirmed by X-rays. [2]
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...
Parsonage–Turner syndrome, also known as acute brachial neuropathy, neuralgic amyotrophy and abbreviated PTS, is a syndrome of unknown cause; although many specific risk factors have been identified (such as; post-operative, post-infectious, post-traumatic or post-vaccination). [4]
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 ...
