Original post
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.

Thanks

An interesting article to consider is written by HJ Sommer. Here's the
pubmed abstract:

A technique for kinematic modeling of anatomical joints.
Sommer HJ 3rd, Miller NR.

Department of Mechanical Engineering, Pennsylvania State University,
University Park 16802.

This paper describes a general technique for fitting a spatial kinematic
model to an in-vivo anatomical joint under typical physiological loading
conditions. The method employs a nonlinear least squares algorithm to
minimize the aggregate deviation between postulated model motion and
experimentally measured anatomical joint motion over multiple joint
positions. Estimation of the parameters of a universal joint with
skew-oblique revolutes to best reproduce wrist motion was used as an
example. Experimental motion data from the right wrists of five subjects
were analyzed. The technique performed very well and produced repeatable
results consistent with previous biomechanical wrist findings.
