@article{Frysz2019, abstract = {Hip shape is an important determinant of hip osteoarthritis and osteoporotic hip fracture; however, little is known about its development in childhood and adolescence. While previous studies largely focused on individual geometrical indices of hip geometry such as neck-shaft angle or femoral neck width, statistical shape modelling offers the means to quantify the entire contour of the proximal femur, including lesser trochanter and acetabular eyebrow. We describe the derivation of independent modes of variation (hip shape mode scores) to characterise variation in hip shape from dual-energy X-ray absorptiometry (DXA) images in the Avon Longitudinal Study of Parents and Children (ALSPAC) offspring, using statistical shape modelling. ALSPAC is a rich source of phenotypic and genotypic data which provides a unique opportunity to investigate the environmental and genetic influences on hip shape in adolescence, as well as comparison with adult hip shape.}, author = {Frysz, Monika and Gregory, Jenny S. and Aspden, Richard M. and Paternoster, Lavinia and Tobias, Jonathan H.}, doi = {10.12688/wellcomeopenres.15092.1}, journal = {Wellcome Open Research}, month = {feb}, pages = {24}, title = {Using statistical shape modelling of DXA images to quantify the shape of the proximal femur at ages 14 and 18 years in the Avon Longitudinal Study of Parents and Children}, url = {https://doi.org/10.12688/wellcomeopenres.15092.1}, volume = {4}, year = {2019} }
