Slipped 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.
In 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.
We 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.
The 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.
股骨头骨骺滑脱（SCFE）是9至15岁儿童中最常见的髋关节疾病。这是一项在瑞典开展的基于人群的研究，呈现了SCFE的流行病学情况。
在一项前瞻性队列研究中，我们分析了2007年至2013年期间瑞典所有接受SCFE治疗儿童的术前和术后X光片、病历、人口统计学数据、滑脱严重程度及所施行的外科手术。
我们确定了2007年至2013年期间379例患有原发性SCFE的瑞典儿童；其中162例为女孩，中位年龄11.7（7.2 - 15.4）岁，217例为男孩，中位年龄13（3.8 - 17.7）岁。9至15岁女孩的年平均发病率为4.4/10000，男孩为5.7/10000。56%的女孩和76%的男孩存在肥胖或超重情况。作为初始症状，66%的儿童有髋部/腹股沟疼痛，12%有膝关节疼痛。初次就诊时，7%的儿童为双侧SCFE。43%的儿童接受了预防性固定。在其余儿童中，21%后来出现对侧滑脱。超过90%的儿童使用了允许进一步生长的植入物进行固定。对11例髋关节施行股骨颈截骨术。
2007年至2013年瑞典的年平均发病率显示女孩略有上升。男女比例低于瑞典之前的地区数据。超重或肥胖是患有SCFE男孩的一个主要特征，但在女孩中程度较轻。以膝关节疼痛作为初始症状会导致诊断延迟。瑞典的大多数医院每年治疗的儿童少于2例。
