Background:
Osteoporotic fractures are a major public concern as a serious, fatal condition. We aimed to investigate the differences in the incidence and types of osteoporotic fractures between people with and without disabilities, including both mental and physical disabilities.
Methods:
This is a serial cross-sectional study using the National Disability Registration and National Health Insurance claims data. After excluding individual with Paget's disease and cancer that damages bone, we analyzed trends and associated factors of osteoporotic fractures between 2008 and 2017.
Results:
The age-standardized incidence rate (ASIR) of osteoporotic fractures was higher in the disabled than in the non-disabled for 10 years (41.3 and 24.0 per 10 000 persons, respectively, in 2017). Vertebral fractures were the most common. However, the incidence of non-vertebral fractures was about twice as high in the disabled as in the non-disabled. In multivariate analysis, the highest odds ratios were observed for epilepsy (OR = 3.80; 95% confidence intervals = 2.40-5.99), liver disease (OR = 2.38), and intellectual disability (OR = 1.95) in men and for epilepsy (OR = 3.19), liver (OR = 1.64), and respiratory (OR = 1.49) disease in women.
Conclusion:
Given the preventability and high incidence of fracture in disabled people, health systems should be designed to ensure timely and appropriate prevention and intervention for disabled people.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
