Under a Wrist

Computer modelling of wrist bones will help understand injury and disease

03 March 2019

Under a Wrist

From typing to eating, driving to lifting, our wrists play a vital role in our daily lives. Here a 3D computer model helps to predict how wrist bones work together. Magnetic resonance imaging scanned the wrists of 18 healthy people, capturing how the bones inside re-organise and collaborate as the joint bends and twists. Pooling information from men and women of different ages produced this general model of ten interlocking bones, but also revealed a strong similarity between left and right wrists, and that male wrist bones are generally larger. The model may now help to make predictions about the effects of injury or disease to our overall manoeuvrability – helping to understand painful conditions such as carpal tunnel syndrome.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
