Normal values and ranges of the lateral capitello-humeral angle in healthy children

Research output: Contribution to journalArticlepeer-review

Abstract

The lateral capitello-humeral angle (LCHA), which is an index of sagittal alignment of the elbow, has gradually been adopted for the postoperative assessment of radiographic results. However, the normal values and ranges of the LCHA remain unclear. A retrospective cohort study was performed to evaluate the normal values and ranges of the LCHA in a sample of healthy children with even distributions of age, sex and laterality. A total of 168 radiographs of the elbows of healthy children (age range, 0-11 years) with even distributions of age, sex and laterality were reviewed. The primary aim was to analyze the normal values and ranges of the LCHA categorized by age, sex and laterality. The secondary aim was to assess the association of the LCHA with increasing age. The LCHA between sex or laterality in each age category was also compared. The mean LCHA of the 168 patients was 47.1° (range, 27°-63°). There was a weak association between the LCHA and increasing age (r = 0.41). The mean LCHA in females (49.1°) was significantly larger than that in males (45.1°). Significant sex-related differences were observed in age categories between 2 and 7 years. Results of this study will be useful in the postoperative radiographic assessment of sagittal alignment of the elbow in children.
