This page is a study of the radiology and anatomy of the distal radius. It is my opinion that we need to study the prepared bone directly, not just rely on studying xrays of fratures. One interesting aspect of studying the dried bone is to examine xrays of isolated distal radii.

This is a dried bone along with its xray in as similar a rotation as possible. Note the thickness of the volar cortex especially as compared to the thin dorsal cortex. Also, the bone projecting volarly of the volar cortex, but proximal to the volar lunate lip, is the volar radial ridge (for more information, see Anatomy Notes. The scaphoid facet and the lunate facets are seen clearly as distinct structures in the xray. The portion of the scaphoid facet that projects distally to that portion that is seen tangentially in Fig 2 is probably not weight bearing, which probably has some relevance as to whether or not it needs as much reduction as the weight bearing portion.

Remember the admonition from the Patient Education Links Page: the Internet has a lot of information, much of it incorrect. I have reviewed the sites that I have linked to, and have only linked to sites when I personally know the surgeon who posted it, or am a member of the organization that posted it. However, I may not agree with all that is on that site, and it may have changed since I reviewed it. If any of the information is not consistent with what I have told you, please download the material and bring it in.
