Final answer:
SCFE generally occurs in early adolescence between 10 to 16 years of age, often in obese children or those undergoing a growth spurt, while Legg-Calve-Perthes Disease usually affects younger children aged 4 to 10, with the average onset at 7 years.
Step-by-step explanation:
Age of Onset: SCFE vs Legg-Calve-Perthes Disease
The age of onset for Slipped Capital Femoral Epiphysis (SCFE) and Legg-Calve-Perthes Disease varies and is key in differentiating between the two conditions. SCFE typically occurs in early adolescence, with most cases presenting in patients aged 10 to 16 years, and it is more common in obese children and during the growth spurt associated with puberty. On the other hand, Legg-Calve-Perthes Disease often appears in children aged 4 to 10 years, with the average being around 7 years of age. Both conditions affect the hip, with SCFE involving a displacement of the upper part of the femur and Legg-Calve-Perthes Disease involving a loss of blood supply to the femoral head, leading to bone necrosis.
