ABSTRACT

Introduction: slipped capital femoral epiphysis (SCFE) is a common condition in pediatric patients that can lead to severe complications if not properly treated. Bone remodeling is crucial for successful recovery, but the factors contributing to complete remodeling (e.g., alpha angle on radiography) are not fully understood. Objectives: to investigate the factors contributing to failed remodeling in patients with SCFE and to describe the diagnostic capability of the alpha angle to predict complete remodeling. Material and methods: 83 patients with SCFE were included. Parameters such as age, laterality, nutritional status, Lodder's classification, and the Southwick angle were evaluated. Comparisons between groups were made to identify factors associated with complete remodeling. Results: complete remodeling was found in 43 patients (51.8%). The presence of an open triradiate cartilage and a lower pre-surgical alpha angle were significantly associated with complete remodeling (p < 0.05). A cut-off value of the alpha angle of 87° showed an AUC of 0.712 (95% CI 0.6-0.82), a sensitivity of 72.5%, and a specificity of 62.8% for predicting complete remodeling. Conclusion: this study identifies the presence of an open triradiate cartilage and a lower alpha angle as important factors in complete remodeling in patients with SCFE. These findings can guide clinical decision-making and emphasize the need for careful evaluation in the treatment of SCFE.
