Classification
The risk factors for a fractured NOF can simplistically be divided into:
- Falls
- Osteoporosis
Note however that there are some things, such as alcohol or immobility, which may be risk factors for both.
Osteoporosis can be classified as:
Primary
- Type 1 (post menopausal)
- Type 2 (senile) age-related osteoporosis which occurs in males and females
- Idiopathic
Secondary
- Endocrine: e.g. Cushing’s syndrome, thyrotoxicosis, hypogonadism, hyperparathyroidism
- Gastrointestinal e.g. malabsorption
- Drugs e.g. corticosteroids, long-term heparin
