Aetiology
The aetiology is unclear and is thought to be multifactorial. It includes: (1)
- obesity -
- 63% of the children who are diagnosed with SCFE have a weight in the 90th percentile or higher
- growth surges
- endocrine disorders
- less common
- related disorders include - hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism
- in patients with unusual presentations (e.g. - patients who are younger than eight years, older than 15 years, or underweight), an endocrine disorder should be considered as the cause of SCFE.
Note:
- trauma causes fracture in a different part of the bone, and it has been variously suggested that it may be caused by hormonal (hypothyroidism and treatment with growth hormone have been implicated) or calcification abnormalities.
- obese children with delayed secondary sexual development, or tall thin boys, appear particularly susceptible to this condition. (2)
