LKnative - Superficial cervical plexus block
2 – Indicated for analgesia after clavicular fracture surgery?
The innervation of the clavicle is controversial (ref. Tran et al, 2013)
Apparently, the supero-anterior aspect of the clavicle is innervated by the supraclavicular nerve from the superficial cervical plexus while the other parts of the clavicle are innervated by nerve branches from the brachial plexus: the suprascapular nerve and the long thoracic nerve (both from the superior trunk of the brachial plexus) – and maybe also the subclavian nerve
The sclerotomal innervation of the clavicle is traditionally ascribed to the C4 spinal nerve root
In 2/3 of human beings the C4 root contributes to the upper trunk of the brachial plexus; or maybe the sclerotomal innervation to the clavicle comes from the C4-C6 nerve roots
