What does the medial cutaneous nerve of the arm supply?

[1] Specifically, the medial antebrachial cutaneous nerve provides sensory innervation of the medial forearm as well as the skin overlying the olecranon. [2] It emerges from the medial cord of the brachial plexus and has sensory cell bodies located in C8 and T1.

What is a median nerve block?

Definition. A median nerve block uses local anaesthetic to block the nerve at the wrist, allowing procedures on the radial side of the palm, palmar surface and tip of the thumb, index and middle finger and (variably) the ring finger.

Where is the medial cutaneous nerve?

forearm
The medial cutaneous nerve of the forearm, also known as the medial antebrachial cutaneous nerve, is a branch of the medial cord of the brachial plexus and supplies the anterior and medial aspects of the forearm as far distal as the wrist.

What is an Interscalene nerve block?

Interscalene nerve block refers to the placement of local anesthetic around the roots or trunks of the brachial plexus at the level of the C6 vertebral body between the anterior and middle scalene muscles. The procedure was first well described and popularized by Alon Winnie in 1970.

Where are the cutaneous nerves located in the arm?

Cutaneous nerves of right upper extremity. The medial brachial cutaneous nerve ( lesser internal cutaneous nerve; medial cutaneous nerve of arm) is distributed to the skin on the medial brachial side of the arm.

Is the medial cutaneous nerve part of the brachial plexus?

As such, it is not a component of the brachial plexus and is, therefore, not anesthetized by any brachial plexus approach. Along with the medial cutaneous nerve of the arm (an intermediary branch of the medial cord), the intercostobrachial nerve provides cutaneous sensation to the upper half of the medial/posterior arm.

Where does the medial antebrachial cutaneous nerve ( MABC ) branch?

Medial Antebrachial Cutaneous Nerve (MABC) Course: The medial antebrachial cutaneous (MABC) nerve branches from the medial cord or the brachial plexus at a point just distal to where the medial brachial cutaneous nerve branches off. They course through the arm in close proximity to each other as well as the basilica vein.

How are blocks of the antebrachial cutaneous nerve injected?

Blocks of the lateral and medial antebrachial cutaneous nerve. Anesthesia for lateral antebrachial cutaneous nerve requires two injections. The first deposits 5 mL local anesthetic just lateral to the border of the biceps tendon. A second 5 mL is then injected subcutaneously and lateral from the first injection site.
