Twenty-six thumb deformities in 16 children with a mean age of 6.2\u00a0years were treated with a mean follow-up of 89.6\u00a0months. Following reconstruction with the Spinner flap, the mean angle of the first and second metacarpal axis (M1M2) showed significant improvement from 42\u00b0 to 61\u00b0 indicating a wider first web space, and the postoperative mean angle of the thumb proximal phalanx to its metacarpal axis (M1P1) was reduced from 41\u00b0 to 18\u00b0, indicative of a straighter thumb. Following reconstruction with a double-opposing Z-plasty, the mean M1M2 and M1P1 also improved from 38\u00b0 to 52\u00b0 and 18\u00b0 to 9\u00b0, respectively. Rerouting of the APB with first web deepening is an efficient and reproducible procedure in improving thumb position.<\/jats:p>\n                  <jats:sec>\n                    <jats:title>Level of
