Nerve Transfers in Tetraplegia

Area of Science:

• Neurosurgery
• Rehabilitation Medicine
• Spinal Cord Injury Research

Background:

• Hand and upper extremity function are crucial for daily living and independence in individuals with cervical spinal cord injury (SCI).
• Restoring function in SCI is a significant challenge, impacting independence and quality of life.
• Nerve transfer surgery presents a promising, albeit complex, avenue for functional restoration.

Purpose of the Study:

• To provide a comprehensive overview of nerve transfer surgery for cervical spinal cord injury (SCI).
• To discuss the biological underpinnings, patient selection, management strategies, and surgical techniques involved.
• To highlight recent advancements and ongoing challenges in the field.

Main Methods:

• Review of current literature on nerve transfers in SCI, including case reports and series.
• Discussion of the biological rationale for nerve transfers in the context of SCI.
• Outline of patient evaluation, pre-operative, intra-operative, and post-operative management protocols.

Main Results:

• Nerve transfer surgery is an evolving technique with increasing interest and application in SCI.
• The procedure aims to reroute functional nerves to reinnervate muscles affected by SCI.
• Evidence from recent studies suggests potential for functional improvement, though challenges remain.

Conclusions:

• Nerve transfer surgery offers a viable option for restoring hand and upper extremity function in cervical SCI.
• Optimizing functional gains and minimizing complications are key challenges requiring further research and refined techniques.
• The principle of 'primum non nocere' (first, do no harm) is paramount in the application of this technique.
