Bone biopsies and serum vitamin-D levels in patients with hip fracture
1Department of Orthopedics, Ichilov Hospital and Sackler School of Medicine, Tel-Aviv University, Israel.
Abstract:
To assess the correlation between osteoid and vitamin D in patients with a proximal femoral fracture, bone biopsies of the fracture site and the iliac crest were studied; and vitamin-D levels were measured in fasting blood taken on the day of admission. No osteomalacia was found at either site in any of the 95 patients investigated. In 65/95 patients, levels of 25-hydroxy-vitamin D (25-OHD) and 24,25-dihydroxy-vitamin D (24, 25-OH2D) were within the normal range, whereas 30/95 patients were deficient. Because there was no correlation between the amount of osteoid and vitamin-D metabolites in our patients, we concluded that osteomalacia was not a contributory factor in the pathogenesis of the hip fracture.

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 D3(cholecalciferol).
Bone Disorders
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.
