What Innervates the regimental badge area?
axillary nerve
The axillary nerve also carries sensory information from the shoulder joint. It also innervates the skin covering the inferior region of the deltoid muscle, known as the regimental badge area. This is innervated by the superior lateral cutaneous nerve branch of the axillary nerve.
What happens if the axillary nerve is damaged?
Axillary nerve dysfunction is nerve damage that can lead to a loss of movement or sensation in the shoulder. Conditions associated with axillary nerve dysfunction include fracture of the humerus (upper arm bone), pressure from casts or splints, and improper use of crutches.
How long does it take for axillary nerve to heal?
Full recovery occurs 85% to 100% of the time with conservative management within 6 to 12 months. Muscle weakness due to the axillary nerve lesion may recover spontaneously as the tissues from the shoulder dislocation heal.
What does the axillary nerve Innervates?
Usually, the axillary nerve contains fibers from the C5 and C6 ventral rami. This nerve innervates the teres minor and deltoid muscles, the skin over the shoulder (upper lateral brachial nerve), and the glenohumeral joint.
What does the axillary artery innervate?
The axillary artery is a large muscular vessel that travels through the axilla. It is responsible for carrying oxygen-rich blood to the upper limb, as well as to parts of the musculocutaneous system of the scapula and upper lateral thorax.
Can an injection hit the axillary nerve?
Injections that occur below the deltoid muscle can hit the radial nerve and injections that are too far to the side of the deltoid muscle can hit the axillary nerve. If a nerve is hit, the patient will feel an immediate burning pain, which can result in paralysis or neuropathy that does not always resolve.
Is radial nerve palsy permanent?
Many patients with radial nerve palsy will see complete recovery or symptom relief after treatment. In some cases, complications may occur, including: Partial or complete loss of feeling in the hand: If the radial nerve doesn’t heal completely, numbness may be permanent.
Is axillary nerve damage permanent?
Recovery following axillary nerve injury The majority of nerve injuries are temporary neuropraxias, which typically resolve within 6-12 months of injury. However, permanent axillary nerve deļ¬cit can occur(8,14).
What is the main function of the axillary nerve?
The axillary nerve’s primary purpose is to supply nerve function to the shoulder joint and three muscles in the arm, but it also innervates some skin in that region, as well.
