PD is reportedly effective for ANs in skeletally immature children. However, no reports have described the foot alignment after PD in skeletally immature children. This study was performed to compare the radiographic parameters between the preoperative period and the final follow-up after PD for symptomatic ANs in skeletally immature children. From October 2013 to December 2020, PD was performed on 13 feet in 10 skeletally immature children. The patients comprised 5 boys and 5 girls with a mean age at surgery of 11.9 years. The mean follow-up period was 14.8 months. We measured 5 radiographic findings preoperatively and at the final follow-up: calcaneal pitch angle (CPA), talocalcaneal angle (TCA), talonavicular coverage angle (TNCA), anteroposterior talo-first metatarsal angle (ATMA), and lateral talo-first metatarsal angle (LTMA). Ten feet were assessed as excellent, 1 as fair, and 2 as poor. Ten unions (76.9%) were achieved among the 13 feet. The mean CPA improved from 16.4\u2005\u00b1\u20054.1\u2009degrees preoperatively to 18.2\u2005\u00b1\u20053.4\u2009degrees at the final follow-up, the TCA improved from 43.0\u2005\u00b1\u20053.7 to 45.2\u2005\u00b1\u20054.4\u2009degrees, and the TNCA improved from 19.9\u2005\u00b1\u20054.4 to 15.4\u2005\u00b1\u20055.0\u2009degrees (<jats:italic toggle=\"yes\">P\u2005&lt;\u2005<\/jats:italic>.05). The ATMA and LTMA were not significantly different between the preoperative period and final follow-up. We found that PD for symptomatic ANs in skeletally immature children was effective treatment, and some radiographic parameters showed significant differences between the preoperative period and final follow-up.<\/jats:p>","DOI":"10.1097\/md.0000000000036643","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T19:01:38Z","timestamp":1703271698000},"page":"e36643","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Radiologic
