Spiral CT Analysis of the Effect of Long-Term Heavy-Load Wrist Movement on Metacarpal Bone Structure

Abstract

In order to analyze the influence of long-term heavy-load wrist exercise on metacarpal structure based on spiral CT, the metacarpal data of five groups of long-term heavy-load wrist athletes and volunteers are compared. The measurement parameters are cancellous bone volume, cortical bone volume, cancellous bone volume percentage and cortical bone volume percentage. After three-dimensional reconstruction and three-dimensional image cutting of metacarpal CT images and comparing the measured parameters, the volume of cancellous metacarpal bone in the experimental group is larger than that in the control group, which indicates that long-term and heavy-load wrist exercise can produce stress stimulation on metacarpal bone, which can reconstruct bone tissue and change its composition.
