Disadvantages of the axillary block include inadequate anesthesia in the distribution of the musculocutaneous nerve.
2.
The most commonly involved nerves are the suprascapular nerve, musculocutaneous nerve, and the axillary nerve.
3.
For example, the musculocutaneous nerve supplies the elbow joint of humans with pain and proprioception fibres.
4.
The resulting palsy has been clinically treated using the phrenic nerve as a donor for neurotization of the musculocutaneous nerve and the median nerve.
5.
Compared to the interscalene block, the supraclavicular block despite eliciting a more complete block of the musculocutaneous nerves does not improve postoperative analgesia.
6.
It contributes to the phrenic nerve, long thoracic nerve, and dorsal scapular nerve before joining cervical spinal nerve 6 to form the upper trunk, a trunk of the brachial plexus, which then forms the lateral cord, and finally the musculocutaneous nerve.
