Reinnervation of spinal cord anterior horn cells after median nerve repair using transposition with other nerves

This study investigates nerve regeneration and motor function recovery following different nerve transposition techniques for median nerve defects in rats. The researchers compared epineurial neurorrhaphy with several nerve transposition methods, assessing wrist flexion, nerve fiber characteristics, and muscle recovery. The findings suggest that nerve translocation from different anterior horn motor neurons can effectively repair median nerve injuries and restore some motor function.

• 1
  Wrist flexion function was restored in all three nerve transposition groups and the epineurial neurorrhaphy group.
• 2
  The magnification of proximal to distal nerves was 1.80, 3.00, 2.50, and 3.12 in epineurial neurorrhaphy group, musculocutaneous nerve transposition group, medial pectoral nerve transposition group, and radial nerve muscular branch transposition group, respectively.
• 3
  Donor nerve translocation from different anterior horn motor neurons can effectively repair the target organs innervated by the median nerve.
