The inclusion criterion was 2 years or more of follow\u2010up. The exclusion criterion was less than 2 years of follow\u2010up. Outcomes were assessed using the visual analog scale (VAS) for pain and the Japanese Society for Surgery of the Foot (JSSF) score.

The mean follow\u2010up duration was 3.2 years (SD \u00b1 0.8 years). One patient had fracture nonunion in the fibular sesamoid and a hypoplastic tibial sesamoid. Another patient had fracture nonunion in the distal part of the congenital bipartite sesamoid. The other patients had fracture nonunion in the normal tibial sesamoids. The mean duration until bone union was 2.9 months (SD \u00b1 0.8 months). The mean duration until returning to sports was 5.3 months (SD \u00b1 3.6 months). The VAS score improved from 72.1 (SD \u00b1 15.2) preoperatively to 12.0 (SD \u00b1 26.7) postoperatively. The JSSF score improved from 58.7 (SD \u00b1 15.8) preoperatively to 95.0 (SD \u00b1 11.0) postoperatively (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.01, respectively).
