The study was carried out at the University of Eastern Finland Bone compositional changes in children with vertebral fractures and after different types of organ transplantation have not been reported previously.
Bone samples were investigated using bone histomorphometry, a microscopic method that provides information about bone metabolism and remodelling. In children with vertebral fractures, there were changes in bone composition, such as lower carbonate-to-phosphate-ratio and increased collagen maturity, which could explain the increased fracture risk. The results also suggest that in children who have undergone kidney, liver or heart transplantation, the various changes related to bone microarchitecture and turnover may be more important predictors of fracture risk than lowered bone mineral density alone. Early detection of such changes in bone quality could help prevent fractures.
