“…Regarding the improvement size between the hypothenar fat pad flap group, the decompression-only group, the autologous fat transfer group, and the “other” group, there was a trend toward a greater improvement when using the hypothenar fat pad flap to treat recurrent CTS. 4 Likewise, in the meta-analysis of Soltani et al, 17 the flap group, which included the hypothenar fat pad flap and other pedicled and free flaps, demonstrated a success rate of 86%, significantly higher than the non-flap group. Factors associated with worse outcomes after a hypothenar fat pad flap include involvement of the nondominant hand, recurrence within a year from the previous surgery, scar tissue in the carpal tunnel, obesity, diabetes mellitus, and cervical spine problems.…”
