Abstrakt:	Background: Contralateral cervical seventh (cC7) nerve to C7 transfer has been proven effective for treating spastic upper limb. However, for those whose major impairment is not in the C7 area, cC7 nerve transfer to other nerves may achieve a better outcome. The aim of this study was to explore the optimal surgical approach for transferring cC7 to 1 or 2 nerves in a cadaveric study, and to evaluate possible applications for patients with hemiplegia. Methods: Modified cC7 transfer to 1 (5 procedures) or 2 nonadjacent (3 procedures) nerve roots was proposed, and success rates of direct coaptation through 2 surgical approaches-the superficial surface of longus colli (sLC) and the deep surface of longus colli (dLC) approach-were compared. The length, diameter, and distance of relevant nerves were also measured in 25 cadavers. Results: Compared with the sLC approach, the distance of the dLC approach was 1.1 ± 0.3 cm shorter. The success rates for the sLC and dLC approaches were as follows: cC7 to C5 surgery, 94%, and reached 98%; cC7 to C6 surgery, 54% and 96%; cC7 to C7 surgery, 42% and 94%; cC7 to C8 surgery, 34% and 94%; cC7 to T1 surgery, 24% and 62%; cC7 to C5C7 surgery, 74% and 98%; cC7 to C6C8 surgery, 54% and 98%; and cC7 to C7T1 surgery, 42% and 88%. Conclusions: The dLC approach greatly improved the direct coaptation rate for cC7 nerve transfer. The modified cC7 nerve transfer procedures are technically feasible for further application in clinic. (Copyright © 2023 by the American Society of Plastic Surgeons.)
