What nerve can be damaged with a clavicle fracture?
Conclusion. Clavicle fractures and/or shoulder surgeries can injure the lateral, intermediary or medial branches of the supraclavicular nerve and cause alteration of sensibility in the anterior aspect of the thorax. Knowledge of the anatomy of the nerve branches helps avoid problems in this region.
What does supraclavicular nerve do?
The supraclavicular nerve is a superficial sensory nerve originating from the C3 and C4 nerve roots of the superficial cervical plexus. This nerve arborizes proximal to the clavicle and provides sensation over the clavicle, anteromedial shoulder, and proximal chest [5, 8].
Where is the supraclavicular nerve located?
The Supraclavicular Nerves (nn. supraclaviculares; descending branches) arise from the third and fourth cervical nerves; they emerge beneath the posterior border of the Sternocleidomastoideus, and descend in the posterior triangle of the neck beneath the Platysma and deep cervical fascia.
What is a cutaneous nerve?
A cutaneous nerve is a nerve that provides nerve supply to the skin.
Where do cutaneous nerves come from?
Cutaneous innervation of the shoulder and upper limb comes from multiple peripheral nerves originating from cervical and thoracic nerve roots, with most of the nerves originating from the brachial plexus.
What is plexus palsy?
Brachial plexus palsy is weakness or paralysis in parts of the arm as a result of significant injury to the brachial plexus, which can happen during childbirth. The most common type of brachial plexus palsy is called Erb’s palsy. Brachial plexus palsy may be caused during childbirth.
What is an axillary nerve?
The axillary nerve arises from the fifth and the sixth cervical nerves that is C5–6. The axillary nerve is a branch of the posterior cord. It is found anterior to the subscapularis, posterior to the brachial artery, and lateral to the radial nerve.
Which main nerve of the upper limb gives off the upper lateral cutaneous nerve of the arm?
Medial Brachial Cutaneous Nerve After branching from the medial cord of the brachial plexus with C8 and T1 contributions, this purely cutaneous nerve courses along the medial side of the upper arm, and pierces the deep fascia and supplies innervation to the cutaneous medial upper arm.
What happens if you damage a cutaneous nerve?
Effects of Injury Injury to the nerve may result in meralgia paresthetica. Meralgia paresthetica is an altered sensation of the lateral cutaneous nerve of the thigh that manifests clinically as numbness, burning, itching, or pain over the anterior and lateral aspects of the thigh.
How long does it take for Meralgia Paresthetica to go away?
It can take some time for your pain to go away. Some people will still feel numbness even after treatment. In most cases, though, you should be able to recover within 4 to 6 weeks.
What is cutaneous nerve damage?
Meralgia paresthetica is a condition characterized by tingling, numbness and burning pain in the outer part of your thigh. The condition is caused by compression of the lateral femoral cutaneous nerve, which supplies sensation to your upper leg.
