    SDN Members don't see this ad. (About Ads)
    I have read different answers from different texts (unless I am missing something). Is it volar or dorsal!

    Thanks!

    You're missing something.

    Dorsal angulation. Or apex volar.

    could you explain a little more about the difference between dorsal angulation and volar apex.

    My understanding is angulation is defined by which way the angle apex points. and therefore a dorsal angulation would have the apex angle point dorsally. Could you help me better understand?

    Thanks! appreciate it

    What Tired said...the concept of apex volar angulation I find easier to show and draw then describe with words...it's just a different concept

    Ironically, the best description I found of this was in a Radiology text.

    From Juhl's Essentials of Radiologic Imaging:

    "When describing displacement of fracture fragments, it is customary to refer to the displacement of the distal fragment in relation to the proximal, the latter being considered as the stationary part. Therefore, one speaks of a posterior displacement of the distal fragment of the tibia in relation to the proximal fragment rather than an anterior displacement of the proximal in relation to the distal. The same method is used in describing dislocations, the distal portion of the extremity being considered to be the dislocated part. For example, all dislocations of the elbow joint are displacements of the bones of the forearm on the humerus. In describing angular deformity, the distal fragment should be considered as being angled in relation to the proximal fragment. Therefore, a fracture of the distal tibia with lateral displacement of the foot would be described as lateral angulation of the distal fragment. As an alternative, the angulation may be defined at the fracture site. In the case described with lateral displacement of the foot, there would be medial angulation at the fracture site. The more common method is to describe the angulation of the distal fragment. Apposition, overlap or overriding, and number of fragments are other important observations."

    Or, since I'm not too smart, I think of it like this: The "angulation" is the direction that the distal aspect of the distal fragment is pointing.

    The ironic part was that I couldn't find anything about this in Wheeless, Rockwood, Chapmans, or Koval. Yet it was bashed into my head from the moment I started interacting with the 'pods. Weird.

    Yep the first orthopod I worked for beat this into my head until I understood it, and described everything via apex angulation...the second one I worked for not so much...but I understand the head beating.
