Background: After stopping the slip progression, hips undergo a remodeling complex phenomenon. Meanwhile femoro-acetabular shock causes irreversible joint cartilage damage. The purpose of the study is to determine if remodeling is sufficient to prevent joint deterioration in the short-term. Methods: A retrospective cohort study of patients with moderate and severe landslides, treated with in situ fixation was designed. Remodeling capacity was evaluated with Southwick angle and alpha angle. Functional and radiological impairment was evaluated with the Hip Harris Score and Tonnis scale, respectively. Minimum follow-up: 4 years. Results: Seventeen patients, median follow-up 63 months (IR 55-81). The pre-surgical Southwick angle 57o (IR 50-72) versus the postoperative one 48o (IR 45-74) significantly decreased (p 0.023). The same happened with the complementary angle alpha. The radiological deterioration was statistically significant (p 0.012). Functional results showed no statistically significant differences (p 0.49). Conclusions: In this series, moderate and severe slipped capital femoral epiphysis fixed in situ showed radiological deterioration during a 63-month follow-up. However, the functionality is not deteriorating as quickly.

Keywords : Slipped capital femoral epiphysis; In situ fixation; Remodeling.
