【 摘 要 】

BackgroundSlipped capital femoral epiphysis (SCFE) is the most common hip disorder in children 9–15 years old. This is a population-based study in Sweden presenting the epidemiology for SCFE.MethodsIn a prospective cohort study, we analysed pre- and postoperative radiographs, medical records for all children treated for SCFE in Sweden 2007–2013, demographic data, severity of slip and surgical procedures performed.ResultsWe identified 379 Swedish children with primary SCFE 2007–2013; 162 girls, median age 11.7 (7.2–15.4) years, and 217 boys, median age 13 (3.8–17.7) years. The average annual incidence was 4.4/10000 for girls and 5.7/10000 for boys 9–15 years old. Obesity or overweight was found in 56% of the girls and in 76% of the boys. As an initial symptom, 66% of the children had hip/groin pain and 12% knee pain. At first presentation, 7% of the children had bilateral SCFE. Prophylactic fixation was performed in 43%. Of the remaining children, 21% later developed a contralateral slip.Fixation with implants permitting further growth was used in >90% of the children. Femoral neck osteotomy was performed for 11 hips.ConclusionsThe annual average incidence 2007–2013 in Sweden showed a mild increase for girls. The male-to-female ratio was lower than previous regional data from Sweden. Overweight or obesity is one major characteristic for boys with SCFE but to a less extent for girls. Knee pain as initial symptom cause a delay in diagnosis. Most hospitals in Sweden treat <2 children annually.
