“…In latitudes north of 40° SCFE presents more frequently in the late summer and autumn months ( Figure 7(a) ) [ 34 , 58 , 59 , 61 , 62 , 106 , 107 ]. Subtracting symptom duration from the time of presentation demonstrates that the SCFE onset is in the early summer/late spring months ( Figure 7(b) ).…”

The Epidemiology and Demographics of Slipped Capital Femoral Epiphysis

2011

The etiology of slipped capital femoral epiphysis (SCFE) is unknown with many insights coming from epidemiologic/demographic information. A systematic medical literature review regarding SCFE was performed. The incidence is 0.33/100,000 to 24.58/100,000 children 8 to 15 years of age. The relative racial frequency, relative to Caucasians at 1.0, is 5.6 for Polynesians, 3.9 for Blacks, and 2.5 for Hispanics. The average age is 12.0 years for boys and 11.2 years for girls. The physiologic age when SCFE occurs is less variable than the chronologic age. The average symptom duration is 4 to 5 months. Most children are obese: >50% are >95th percentile weight for age with average BMI is 25–30 kg/m2. The onset of SCFE is in the summer when north of 40°N. Bilaterality ranges from 18 to 50%. In children with bilateral involvement, 50–60% present with simultaneous SCFEs and those who present with a unilateral SCFE and subsequently develop a contralateral SCFE do so within 18 months. The age at presentation is younger for those who present with a unilateral SCFE and later develop a contralateral SCFE. The age-weight, age-height, and height test are useful to differentiate between an idiopathic and atypical SCFE.

Abstract. This paper investigates the relation between metaphyseal zone fragility and growth rate. It is concluded that there are two sites of weakness, the hypertrophic zone of the plate and the metaphysis. From a study of the age incidence of traumatic plate fractures compared with that of shaft fractures, it is deduced that fragility of both zones is a non-linear function of growth rate. It is concluded that this correlation explains the occurrence and age incidence of a range of diseases in which plate fractures occur in shear, and of central Schmorl's node which is a metaphyseal fracture in compression. The mechanism of plate fragility appears to be an increase in thickness of the hypertrophic zone from any cause, including rickets as well as increased growth. No evidence is found to implicate endocrine imbalance as a necessary factor in the normal transient fragility of the growth spurt.Key words: Growth plate --Bone growth --Plate fracture -Metaphysis Battered child --Epiphysidysis --Scheuermann's disease. rate, and to determine if possible which of the three mechanisms is the most likely.

“…Low socioeconomic Season Summer season and hours of sunshine are correlated with childhood fracture rates. While slipped capital femoral epiphysis, a Salter I fracture, may be more prevalent in the summer season, 26 Landin's 2 1983 series did not show any significant seasonality in physeal injuries. 24,25 Additionally, the days with above-average sunshine have double the fracture admission rate than days with below-average sunshine.…”

Despite public health measures to prevent childhood injuries, the incidence of pediatric fractures is increasing. This fracture incidence is dependent on many demographic factors, the various contributors to bone health, and an individual's risk-taking behavior. Although traditional play activities continue to be the prevalent causes for fractures, there is an evolving array of new sport and recreation activities that carry significant fracture risk. The following review article outlines the developing epidemiology of pediatric fractures by analyzing some of the individual risk factors that influence fracture incidence as well as the variety of activities that are associated with these fractures.
