Summary:

Objective: to evaluate the effectiveness of surgery in children with secondary proximal hip deformity and acetabular dysplasia. Material and methods. The study included 60 children (65 joints) of 9-16 years old (the average age was 12.5 years old). We divided all patients into two age groups: group 1 — children aged 9 to 12 years old (35 joints), group 2 — children aged 13 to 16 years old (30 joints). We used various surgical tactics; the choice depended on the examination methods and results. Long-term results were followed up to 7 years after the intervention. We assessed the treatment outcomes using Tschauner-Hempel equations and McKay scale. Results. Group 1 featured excellent outcomes in 48.6% of cases, good outcome in 42.8%, satisfactory outcome in 8.6% of cases. Group 2 featured two unsatisfactory outcomes, excellent outcomes in 36.6%, good outcomes in 32.3% and satisfactory outcomes in 24.5% of cases. Conclusion. According to the long-term results of radiometric and functional indicators, surgical correction of residual deformations in hip dysplasia in children and adolescents is a highly effective tool for preventing the development of early coxarthrosis. In order to obtain good and satisfactory treatment outcomes, surgery tactics should rely on a thorough analysis of the anatomical-functional state of the hip joint, taking into account the age of the patient. More optimal for surgical prevention of early hip osteoarthritis is 9 to 12 years of age.
