View Full Version : Wrist anatomical coordinate system

07-08-2005, 05:32 AM
Dear Biomch-L subscribers,

I am trying to create a 3D model for the wrist/hand rotations. I have done a
literature search trying to find how to define the anatomical coordinate
system for the wrist using magnetic tracking device and define anatomical
coordinate system by digitizing anatomical landmarks. The ISB proposal is
using a volume data of the 3rd metacarpal bone to define this coordinate
system (we donít have this option in our lab)and defining neutral position.
Most of the articles I have found are using 3D scanning devices (MRI etc.)
or just using one marker to define the hand without calculating the
rotational axes. Does anyone have any experience in creating an anatomical
coordinate system for the wrist/hand by digitizing bony landmarks? I will
appreciate any ideas or thoughts on this issue.
I will post a summary of the responses.
