region was then used as the outer layer for the cancellous bone.
The 3D models of the wrist were constructed using AMIRA software (Mercury
Computer Systems, Inc., San Diego, CA) where an automatic compilation through
the software's marching cubes algorithm was applied, which generates a 3D tri-
angular surface mesh. An average element size of 0.4 mm was chosen which
resulted in an accurate geometric description of the bone geometry. The created
models were compared with an anatomy software [ 2 ], and were considered
acceptable to mimic the healthy wrist joint. Boolean operations were occupied to
check for any intersecting bodies.
