Epidemiology and demographics of slipped capital femoral epiphysis in South Korea: A nationwide cohort study

Abstract

Background This study investigated the epidemiology and demographics of slipped capital femoral epiphysis (SCFE) in South Korea using a nationwide population-based database. Methods Information on sex, age at onset, endocrine comorbidities, history of growth hormone therapy, history of radiation therapy, surgical methods, and complications in patients with SCFE aged younger than 18 years between 2007 and 2019 was retrieved from the Korean Health Insurance Review and Assessment Service database. Results Data were available for 586 children (429 boys, 157 girls). The average age at onset was 11.1 ± 1.8 years (boys, 11.3 ± 1.9; girls, 10.6 ± 1.5). Five hundred and twenty-nine (90.3%) patients were aged 9–14 years; the incidence rate in this age group was 6.0/100,000 (95% confidence interval, 5.5–6.6) and significantly higher in boys (8.4 vs 3.5, p<0.001). There was a significant increase in the annual incidence rate from 0.96/100,000 in 2009 to 2.05/100,000 in 2019 (p = 0.006). Ninety-five patients (16.2%) had endocrine comorbidities or a history of hormone/radiation therapy. Osteotomy and internal fixation were performed in 59 patients and in situ pinning in 527. Seventy-six patients developed postoperative complications. Conclusion The annual incidence rate of SCFE in South Korea has increased since 2009.

Slipped capital femoral epiphysis in an adolescent with congenital adrenal hyperplasia: A case report

“…Slipped capital femoral epiphysis (SCFE) is a complication of the proximal femur commonly seen in adolescents. It is defined as the displacement of the metaphysis relative to the epiphyses 1 A previous study regarding SCFE in the Asian population indicated that the incidence in children 9 to 14 years of age was 6.0/100,000, 2 with obesity and puberty being important risk factors. 3 In recent years, endocrine disorders such as hypothyroidism, hyperparathyroidism, hypogonadism, and hypopituitarism have increasingly been reported as causes of SCFE.…”
