A method is presented to reinforce normal suturing techniques in median and ulnar nerve repairs at the level of the forearm or wrist. If the distance between the stumps does not exceed 20 to 30 mm the coaptation can be protected from tension by two ribbons of polydioxanone (PDS) which are sutured to the epineurium bridging the site of the suture of the nerve. PDS ribbons proved to give remarkable support to experimental nerve repairs using epineural, perineural or Tsuge suture techniques. In further experiments with tibial nerves of rats the PDS ribbon did not interfere with the nerve function or with axon sprouting. Follow-up investigations of thirty-two median and ulnar nerve injuries treated with primary or secondary interfascicular sutures using PDS ribbons of 20 mm length and 1 mm width to protect the suture line revealed satisfactory reinnervation. The late results with this method were superior to a comparable group treated with autografts.
本文介绍了一种在前臂或腕部正中神经和尺神经修复中强化常规缝合技术的方法。如果神经残端之间的距离不超过20至30毫米，可通过两条聚二氧六环酮（PDS）带保护神经吻合处免受张力，这两条带缝合于神经外膜，跨越神经缝合部位。事实证明，PDS带对采用神经外膜、神经束膜或津下缝合技术的实验性神经修复提供了显著支持。在大鼠胫神经的进一步实验中，PDS带未干扰神经功能或轴突萌发。对32例采用20毫米长、1毫米宽的PDS带进行一期或二期束间缝合以保护缝合线的正中神经和尺神经损伤病例的随访研究显示，神经再支配效果令人满意。该方法的远期效果优于采用自体移植的对照组。
