Kinematic analysis of relative motion within the proximal carpal row
|
abstract
|
The motions of the scaphoid and triquetrum relative to the lunate
have been studied on cadaver specimens. The helical axis concept was
applied. The wrist motions performed were flexion-extension and
radial-ulnar deviation. The results showed increased relative motion
of the scaphoid towards terminal extension, and to a lesser amount
in the case of the triquetrum, towards terminal flexion. The lunate
might be considered as a keystone in the proximal carpal row when
wrist stability is considered. It is doubly intercalated:
longitudinally and transversely. Wrist ligaments co-ordinate the
positioning of the bones in the mid-range of carpal motions, and
restrict further motion in extreme positions of the wrist joint.
