Abstract
Objective. The purposes of the present study were to investigate the feasibility of using a
skin sensor to represent the first and third metacarpal bone, to verify that there
was no significant relative motion between the skin of the third metacarpal bone and
trapezium bony segment and to measure thumb metacarpal motion with respect to the
hand (third metacarpal).
Design. Eight hands from fresh-frozen human cadavers were disarticulated 4 cm proximal to
the wrist joint and used in this experiment.
Background. Recently, magnetic-tracking systems have been developed for the measurement of joint
kinematics. Based on the concept of the three-dimensional space within which the thumb
metacarpal bone can move, the current study proposes a 3D method for evaluating the
relationship between the skin and bony segment.
Methods. An electromagnetic tracking system was used to provide quantitative measurement
and evaluation of the relationship between the skin and bony segment while moving
the trapeziometacarpal joint.
Results. The adjusted coefficient of multiple determination, Ra2, values of the kinematic waveforms between the sensors were larger than 0.84. The
angular differences and displacements of the center of sensors between the skin and
bony sensors were less than 4.9° and 2.8 mm.
Conclusion. These data revealed that the similarities of the two sensors throughout the motion
cycle were high. The differences between the two sensors were also within the clinically
allowable range of ±5°. Therefore, it is feasible to collect motions of the first
metacarpal by attaching the skin sensors at the metacarpal head to measure the bony
segment.
