Understanding The Supraclavicular Block: An In-Depth Guide To Nerve Blockade
The supraclavicular block targets nerves within the supraclavicular fossa, which lies above the clavicle and below the first rib. The block targets the suprascapular nerve, innervating the supraspinatus and infraspinatus muscles; the axillary nerve, supplying the deltoid, teres minor, and teres major muscles; the radial nerve, extending the elbow and controlling forearm and hand movements; the musculocutaneous nerve, innervating the biceps brachii and brachialis muscles; the median nerve, supplying the thenar eminence and forearm pronators; and the ulnar nerve, innervating the hypothenar eminence and intrinsic hand muscles.
