Background The purpose of this study was to evaluate the clinical, functional and radiological outcome of calcaneal lengthening osteotomy for the treatment of symptomatic flatfoot deformity in skeletally immature patients. Methods A retrospective review was led on 31 prospectively enrolled patients with symptomatic flatfoot. Twenty-seven out of 31 patients met the inclusion criteria, for a total of 38 operated feet. Mean age at time of surgery was 13.3 ± 2.2 years (range 7.8–17). Mean BMI at time of surgery was 19.3 ± 4.9 (range 12.3–32). In order to assess clinical and functional outcome, all patients were evaluated according to Yoo et al., Mosca and AOFAS clinical criteria before surgery and at last follow-up visit. Moreover, all patients underwent anteroposterior and lateral weight-bearing foot radiographs preoperatively, at 3–4-month post-surgery and at last follow-up visit. Results Average Yoo et al. score was 3.3 ± 1 (range 0–4) preoperatively and improved to 9.8 ± 2.1 (range 3–12) at last follow-up ( p
