Objective To observe the effect of superficial radial nerve transplanting to repair musculospiral nerve defection and using end-to-side neurorrhaphy to reconstruct the function of the donor site. Methods Thirtyfour cases underwent superficial radial nerve transplanting to repair musculospiral nerve defection and end-to-side neurorrhaphy was performed to reconstruct the function of the donor site. Results All cases were followed-up for 6 to 18 months,the functional recovery of the recipient of musculospiral nerve was excellent in 23 cases and good in 5 cases,with an excellent and good rate of 82. 53 %. Sensory recovery of donator nerve was excellent in 27 cases and good in 5 cases,with an excellent and good rate of 94. 12%. Conclusions Superficial radial nerve transplanting to repair musculospiral nerve defection and functional reconstruction of donor site is a better choice in treating neurologic defect.
