Summary

End-to-side nerve suture (ETSNS) facilitates axon sprouting for nerve repair. This technique shows promising results in restoring motor and sensory function in patients with peripheral nerve injuries.

Area of Science:

  • Neurosurgery
  • Peripheral Nerve Regeneration

Background:

  • Axon lateral sprouting into recipient nerves via end-to-side suture is documented.
  • The precise mechanisms require further investigation.
  • Extensive primate research and clinical application of end-to-side nerve suture (ETSNS) since 1996.

Purpose of the Study:

  • To evaluate the efficacy of ETSNS in clinical practice for peripheral nerve repair.
  • To analyze outcomes in patients undergoing ETSNS for various nerve conditions.
  • To discuss the indications, technique, and rehabilitation for ETSNS in human patients.

Main Methods:

  • Application of the end-to-side nerve suture (ETSNS) technique in 56 patients.
  • Inclusion of diverse conditions: brachial plexus avulsion to digital nerve lesions.

  • Continuous involvement in primate research alongside clinical practice.
  • Main Results:

    • Successful proximal motor re-innervation (e.g., biceps).
    • Effective distal sensory re-innervation (e.g., volar hand skin).
    • ETSNS restores function in previously challenging cases.

    Conclusions:

    • ETSNS is a valuable addition to peripheral nerve surgery armamentarium.
    • The technique can potentially replace nerve grafting in numerous scenarios.
    • ETSNS offers a viable solution for complex nerve injuries, improving patient outcomes.
