Application of the self-made nerve bundle with 3 mm of spatial distance between the two ends in repair of median nerve rupture of the wrist
Objective To investigate the application effect of the self-made nerve bundle with 3 mm of spatial distance between the two ends in repair of median nerve rupture of the wrist.Methods A total of 24 patients with median nerve rupture of the wrist from July 2014 to August 2020 were included.The self-made nerve bundle with 3 mm of spatial distance between the two ends was applied,and then the epineurium was anastomosed continuously,and no nerve bundle was exposed.After 4 weeks of plaster external fixation,functional exercise was gradually strengthened.The median nerve recovery was evaluated according to Burchiel efficacy evaluation criteria.Results At the last follow-up,the sensory recovery of the middle finger reached S4 level,the functions of thumb to palm and finger to finger recovered,and the thenar eminence was full without atrophy.At the last follow-up,the median nerve recovery was excellent in 18 cases,good in 6 cases,and the excellent and good rate was 100% .Conclusion The epineural anastomosis of self-made nerve bundle with 3 mm of spatial distance between the two ends can achieve accurate counterpoint,prevent scar compression,avoid neuroma,and effectively restore the function of the median nerve.
