Bone density and geometric properties of the distal radius in displaced and undisplaced Colles' fractures: Quantitative CT in 70 women

We examined cortical and trabecular bone density and geometric properties of the unfractured distal radius in 70 women with recent Colles' fractures, using multilayer peripheral quantitative computed tomography (pQCT). We found that cortical volumetric density, cortical area and mean cortical t...

Description
Summary:We examined cortical and trabecular bone density and geometric properties of the unfractured distal radius in 70 women with recent Colles' fractures, using multilayer peripheral quantitative computed tomography (pQCT). We found that cortical volumetric density, cortical area and mean cortical thickness were lower in the displaced than in the undisplaced fractures, suggesting that the cross-sectional volumetric density and geometric properties of cortical bone may be essential in determining the severity of a Colles' fracture. We also compared lumbar spine and femoral neck bone mineral density (BMD) and the occurrence of osteoporosis in the displaced and undisplaced fracture groups and found no significant difference, which suggests that displacement of a Colles' fracture is not associated with general osteoporosis.
