Summary

Reoperation for cubital tunnel syndrome after initial neurolysis yielded satisfactory outcomes in approximately half of the cases. Submuscular transposition may be beneficial as a second reoperation when prior subcutaneous transposition failed.

Area of Science:

  • Orthopedic Surgery
  • Neurosurgery
  • Hand Surgery

Background:

  • Cubital tunnel syndrome, a common entrapment neuropathy, can necessitate reoperation if initial treatments like neurolysis fail.
  • Recurrent or persistent symptoms after primary ulnar nerve decompression present a surgical challenge.

Purpose of the Study:

  • To evaluate the efficacy of reoperation for cubital tunnel syndrome in patients with prior unsuccessful neurolysis.
  • To compare outcomes of different surgical techniques (subcutaneous vs. submuscular transposition) during reoperation.

Main Methods:

  • Retrospective analysis of 16 arms in 14 patients undergoing 22 reoperations for cubital tunnel syndrome after failed neurolysis.
  • First reoperations involved subcutaneous transposition (10 arms) or submuscular transposition (6 arms).
  • Submuscular transposition was performed as a second reoperation in 6 arms with prior failed neurolysis and subcutaneous transposition.

Main Results:

  • Overall, reoperation provided satisfactory results (cure or improvement) in approximately 50% of cases.
  • Initial reoperation with subcutaneous transposition led to improvement in 7/10 arms, while submuscular transposition improved 6/6 arms.
  • Second reoperation with submuscular transposition after failed neurolysis and subcutaneous transposition resulted in improvement in 5/6 arms.

Conclusions:

  • Reoperation for cubital tunnel syndrome following failed neurolysis offers moderate success rates.
  • Submuscular transposition appears to be a potentially effective option for second reoperation, particularly after failure of subcutaneous transposition.
