Effectiveness of the hypothenar fat pad flap in revision surgery for recurrence of carpal tunnel syndrome.

This study compared open decompression and the hypothenar fat pad flap for recurrent carpal tunnel syndrome. Both techniques led to significant improvements in pain (Visual Analog Scale), the DN4 neuropathic pain questionnaire and QuickDASH scores, with no statistically significant differences between the groups at a long-term 10-year follow-up.
