Longitudinal postnatal growth of the first metatarsal bone
Abstract
Background: while prenatal and postnatal growth of the foot has been documented several years ago, longitudinal growth of the first metatarsal has not been previously evaluated. The aim of the study is to determine the postnatal longitudinal growth pattern of this bone and compare it with the foot and lower limb long bones.Methods: through a computerized image search, we identified patients <18 years old with radiographs reported as “normal” by the radiologist. A sample of 886 patients was divided into 18 groups according to age (0-11 months, 1 year, 2 years, etc.) and sex. Analysis was performed using Kodak Carestream imaging software PACS.Results: the average length in the first group was 19.91 mm (3.20, 15.22-25.62). The average length in the last group was 66.13 mm (5.33, 52.50-77.18). Annual growth rate was 2.71 mm. The average age at the time of physeal closure was 14.85 years (± 1.64) for boys and 14.77 years (± 3.63) for girls.Conclusion: longitudinal growth of the first metatarsal mimics the growth of foot but not that of the long bones of the lower limb. Growth curves described in this article can be applied to conditions that affect foot development or require corrective surgery on the first metatarsal, as well as a standard reference in future studies.Downloads
