Research

Research in the bone group focuses on osteoporotic fragility fractures and osteoarthritis by examining bone structure, shape and biology in health and disease. As part of a team lead by imaging experts Graham Treece and Andrew Gee from the University Engineering department, we developed a way of assessing the 3D structure and shape of cortical bone structure in life called Cortical Bone Mapping (CBM). We have used CBM, histology and microCT to discover that there are defined patches of focal osteoporosis in older people’s femurs that predispose them to hip fracture. CBM measurements from clinical CT predict hip fracture well. Analysing separate clinical trials, we found that teriparatide PTH1-34 and denosumab anti-RANK ligand antibody treatment of osteoporotic women improved bone in patches of the femur at risk of fracture. Older men undertaking high-impact short-duration exercise (the HIPHOP study) also responded well, with focal patches of cortical bone improving on CT.

Within the Department of Medicine, we represent the Division of Rheumatology and within Cambridge NIHR Biomedical Research Centre we represent the 'Metabolism, Endocrinology and Bone'  theme. Evelyn Trust funding allowed us to purchase the UK’s first high resolution Xtreme CT scanner, and have supported clinical radiology researcher Dr Tom Turmezei to carry forward the shape and image analysis techniques into the field of osteoarthritis. He has published key papers on the assessment of hip osteoarthritis with novel CT techniques. We make use of the Wellcome Trust Clinical Research Facility (WTCRF) for our clinical studies. Our clinical trials research includes an investigator-led  proof of concept study demonstrating that a single dose of intravenous zoledronate prevents bone loss after stroke.

Arthritis Research UK, the Medical Research Council, the Evelyn Trust, the National Osteoporosis Society, Addenbrooke's Charitable Trust and the Cambridge NIHR Biomedical Research Centre support our current research program.
