Preliminary evaluation of the calcaneo-stop technique for flexible flatfoot in children

Resumo

Objectives: this study aimed to evaluate the clinical and radiographic outcomes, as well as caregiver satisfaction, in children who underwent the calcaneo-stop procedure. Methods: patients aged 11 to 13 years were included in the study. The changes in the American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot and Ankle Evaluation Scale, reference radiographic angles (Calcaneal Pitch, Kite Angle (AP View), Kite Angle (Lateral View), Meary’s Angle, and Giannestras Angle), caregiver satisfaction, and sample characteristics regarding age, sex, and family history were assessed. The pre- and postoperative results were compared. Statistically significant improvement was observed in the AOFAS scale score and favorable radiographic correction. Results: the mean age of the cohort was 11.5 years, and a positive family history of flexible flatfoot was identified in 62.5% of cases. Based on the Smith–Millar criterion, surgical outcomes were classified as good in 86.7% of patients and excellent in 13.3%. Postoperative complications were uncommon, with 93.3% of patients remaining complication-free. Significant functional improvement was observed, demonstrated by increased AOFAS scores, enhanced foot function, and radiographic correction of the Kite, Meary, Giannestras, and Calcaneal Pitch angles. Conclusion: the calcaneo-stop technique demonstrated safety and efficacy, providing significant clinical and radiographic improvement and yielding high levels of caregiver satisfaction.
