Morphological Study of the Anterior Surface of the Distal Radius

الملخص EN

The shape of the anterior surface of the distal radius is important for designing a distal radius plate for wrist fracture surgery.

The aim of this study was to describe the shape of the anterior surface of the distal radius and to compare the results between female and male.

We used 90 sides from three-dimensional radial models based on computer tomography images from Korean adult cadavers for this study.

The anterior surface was measured in two dimensions in the coronal view, and we sectioned the anterior surface of the models to obtain intermediate and radial sections to measure the curved shape of the anterior surface in sagittal view.

Several parameters were statistically different between females and males; however, there were no differences between the right and left sides for any parameters.

The width of the anterior surface in the coronal view was larger in males than females, and the curved part of the anterior surface of the males was longer and more concave than that of females.

In both the female and male specimens, the intermediate section was longer and more concave than the radial section.

Our results are useful for anthropological studies and for designing distal radial plates.
