Serum Calcium, Vitamin D Levels in Pediatric Flatfoot Patients That were Brought to Clinic with or without in-Toeing Complaint

INTRODUCTION: This study aims to evaluate the serum levels of calcium and Vitamin D in pediatric patients with flatfoot, who were brought to clinic with or without in-toeing compliants.
METHODS: Flatfoot patients who were followed up between November 2017 and December 2019 were divided into four groups. Group A included patients who had flatfoot with in-toeing. Group B included patients who had flatfoot without in-toeing. Group C included patients who had in-toeing without flatfoot. Group D was the control group and it included patients who had neither flatfoot nor in-toeing. Group D had no other acquired or congenital diseases via to the pediatric age. Serum levels of calcium and Vitamin D were detected by biochemical assays on study and control groups.
RESULTS: In this study, four study groups included 204 children who were divided in to four groups as Group A, B, C and D. All groups included 51 (%25.0) patients. According to test results, in the serum calcium levels, there was a significant difference between Group A and Group D in favor of the control group (p=0.040). There was no significant difference between serum vitamin D levels and foot deformities (p=0.457). The relationship between calcium values and foot deformities was significant (p=0.004). The relationship between vitamin D values and foot deformities was not significant (p=0.457).
DISCUSSION AND CONCLUSION: The coexistence of flatfoot and in-toeing may be related to lower serum calcium levels. Flatfoot with or without in-toeing has no relationship with serum Vitamin D levels.
