Hindfoot Alignment in Pediatrics: The Relationship Between Hindfoot Moment Arm and Hindfoot Alignment Angle.
Background: Various measurements are used to evaluate hindfoot alignment and determine appropriate treatment, though the best tool is not known. Few studies have examined the relationship between these measurements in pediatric patients. This study sought to compare Hindfoot Moment Arm (HMA) and Hindfoot Alignment Angle (HAA) in evaluation of pediatric hindfoot deformity.
Methods: This was a retrospective cohort study of pediatric patients by age: school-aged (7 to 10 years old), preadolescents (11 to 14), and adolescents (15 to 18). A total of 10 males and 10 females were randomly selected for each cohort from patients with available hindfoot radiographs. HMA and HAA were measured by 2 independent reviewers. Pearson correlation of HMA and HAA was performed by age cohort. Multivariable linear regression was used to investigate the association of HMA and HAA adjusting for age, sex, height, and weight.
Results: Sixty participants were analyzed. Interrater reliability was found to be excellent for HMA and HAA (ICC=0.996 and 0.992, respectively). HMA was 8.7±9.4 mm in school age, 5.7±6.7 mm in preadolescents, and 2.5±13.0 mm among adolescents ( P =0.153). HAA was 6.3±9.7 degrees in school age, 6.7±8.6 degrees in preadolescents, and 6.0±14.5 degrees among adolescents ( P =0.983). The Pearson correlation coefficient was 0.78 (CI: 0.51-0.91) for school-aged, 0.92 (CI: 0.81-0.97) for preadolescents, and 0.86 (CI: 0.67-0.94) for adolescents. Using multivariable regression, each degree increase in HAA, increased HMA by 0.77 mm. Age, height, and weight were not found to be independent predictors of HMA.
Conclusions: HMA and HAA were both found to be reliable measurements across all age cohorts. When comparing across age cohorts, neither HMA nor HAA differed significantly ( P =0.153 and 0.983, respectively). Furthermore, Pearson correlation demonstrated a linear relationship between HMA and HAA. When evaluating hindfoot deformity, surgeons may assess hindfoot alignment via either HMA or HAA regardless of patient age. The authors support the use of HMA for clinical and academic purposes as HMA is considerably simpler to measure.
