Vitamin D deficiency is common in children with fractures. Supplementation with vitamin D3 significantly improved levels during healing, highlighting the importance of testing and treatment for pediatric fracture patients.
Area of Science:
- Pediatric Orthopedics
- Endocrinology
- Nutritional Science
Background:
- Vitamin D plays a crucial role in bone health and fracture healing.
- Prevalence of vitamin D deficiency and insufficiency in pediatric populations is a growing concern.
- Optimal vitamin D levels are essential for effective bone repair in children.
Purpose of the Study:
- To assess vitamin D levels in children undergoing treatment for fractures.
- To evaluate the impact of vitamin D supplementation on fracture healing in pediatric patients.
- To determine the prevalence of vitamin D deficiency and insufficiency at the time of injury in children.
Main Methods:
- A four-year prospective study involving 63 healthy children with diaphyseal femur or forearm fractures.
- Vitamin D levels, along with P1NP, ALP, GGT, and parathormone, were measured at injury, and at 1, 3, and 5 months post-injury.
- Participants were randomized into two groups: one receiving vitamin D3 supplementation, the other not.
Main Results:
- At injury, 42% of children had vitamin D deficit, 36.5% insufficiency, and 21.5% normal levels.
- Children supplemented with vitamin D3 showed statistically significant increases in vitamin D levels within one month, which were sustained.
- Supplemented groups demonstrated better outcomes regardless of initial vitamin D status or fracture type.
Conclusions:
- A high prevalence of vitamin D deficiency/insufficiency exists in healthy children presenting with fractures.
- Vitamin D3 supplementation is effective in normalizing vitamin D levels in pediatric fracture patients within one month.
- Routine vitamin D testing and supplementation are recommended for children treated for fractures to support optimal healing.

Role of Vitamins in Maintaining Bone Health
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...
Fractures: Bone Repair
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...
Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
