Purpose.
We have observed worsening thumb pain following carpal tunnel release (CTR) in some patients.
Our purpose was to determine the effect of open CTR on thumb carpometacarpal (CMC) biomechanics.
Methods.
Five fresh-frozen cadaver arms with intact soft tissues were used.
Each specimen was secured to a jig which fixed the forearm at 45° supination, and the wrist at 20° dorsiflexion, with thumb pointing up.
The thumb was axially loaded with a force of 130 N.
We measured 3D translation and rotation of the trapezium, radius, and first metacarpal, before and after open CTR.
Motion between radius and first metacarpal, radius and trapezium, and first metacarpal and trapezium during loading was calculated using rigid body mechanics.
Overall stiffness of each specimen was determined.
Results.
Total construct stiffness following CTR was reduced in all specimens but not significantly.
No significant changes were found in adduction, pronation, or dorsiflexion of the trapezium with respect to radius after open CTR.
Motion between radius and first metacarpal, between radius and trapezium, or between first metacarpal and trapezium after open CTR was not decreased significantly.
Conclusion.
From this data, we cannot determine if releasing the transverse carpal ligament alters kinematics of the CMC joint.
