Summary
Phrenic neurotization successfully restored function in most brachial plexus patients with root avulsions. This nerve transfer surgery showed significant recovery and no adverse respiratory effects long-term.
Area of Science:
- Neurosurgery
- Orthopedics
- Regenerative Medicine
Background:
- Brachial plexus injuries, particularly root avulsions, often result in significant upper extremity dysfunction.
- Restoring function requires innovative surgical techniques like nerve transfers.
Purpose of the Study:
- To evaluate the efficacy of phrenic neurotization for brachial plexus root avulsion injuries.
- To assess functional recovery and long-term outcomes after phrenic nerve transfers.
Main Methods:
- A retrospective review of 164 patients undergoing phrenic neurotization to brachial plexus components.
- Recipient nerves included the musculocutaneous, median, and other nerves.
- Follow-up data, including functional recovery (M-3 grade or better) and respiratory function, were analyzed.
Main Results:
- Phrenic neurotization was performed on 164 patients with brachial plexus root avulsions.
- The musculocutaneous nerve was the most common recipient (125 patients).
- In patients with ≥2 years follow-up (65), 84.6% achieved M-3 or better motor recovery, with no negative impact on respiratory function.
Conclusions:
- Phrenic neurotization is an effective treatment for brachial plexus root avulsions.
- The procedure yields high rates of functional recovery without compromising respiratory function.
- This nerve transfer technique offers a viable option for managing severe brachial plexus injuries.
