LATERAL LUMBAR VERTEBRAL SHAPE RELATED TO BONE MINERAL DENSITY AT L1L4

British Orthopaedic Research Society (BORS) Annual Conference



Abstract

The shape of the vertebral bodies from L1 to L4 was assessed from lateral dual-energy x-ray absorptiometry (DXA) images using an active shape model. The output from the model was compared to measurements of areal bone mineral density in L1 to L4 (aBMD) using a stepwise linear regression model. A significant relationship was found between aBMD and vertebral shape that suggests that the method may be useful for correcting artefacts such as osteophytes.
