Summary
Reinnervating the brachial plexus after root avulsion can utilize the spinal accessory nerve. This study analyzes its effectiveness in 13 patients, with supplementary nerve transfers in some cases.
Area of Science:
- Neurosurgery
- Peripheral Nerve Surgery
- Reconstructive Surgery
Background:
- Brachial plexus root avulsion causes paralysis, necessitating reinnervation strategies.
- The spinal accessory nerve is a potential donor for restoring function.
- Evaluating reinnervation outcomes is crucial for surgical planning.
Purpose of the Study:
- To analyze the efficacy of spinal accessory nerve transfer for brachial plexus reinnervation.
- To assess outcomes in patients with total and partial root avulsions.
- To compare surgical techniques and outcomes.
Main Methods:
- Retrospective analysis of 13 patients undergoing brachial plexus reinnervation.
- Utilized the spinal accessory nerve as the donor nerve.
- Allieu's technique was employed, with supplementary transfers (intercostal or medial pectoral nerves) in 7 cases.
Main Results:
- Successful reinnervation of the musculocutaneous or axillary nerve was observed.
- Outcomes varied based on the extent of avulsion (total vs. partial).
- Supplementary nerve transfers potentially improved functional recovery.
Conclusions:
- Spinal accessory nerve transfer is a viable option for brachial plexus reinnervation post-avulsion.
- Combined techniques may enhance functional restoration in complex cases.
- Further comparison with intercostobrachial anastomosis is warranted.

01:23Spinal Nerves: Anatomy
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:12Arteries of the Upper Limbs
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
