Abstract
Cadaver forearms were tested to measure carpal bone separation and wrist ligament tension in response to MTS-based incremental wrist distraction. Distraction of 2 mm separated the proximal carpal row from the radius and transmitted an average tension of 8 N. The midcarpal joint also began to widen at this level of distraction. Distraction of 4 mm resulted in an average tension of 20 N. At this level of distraction, radioscaphoid separation started to exceed radiolunate separation. A transition from low-to high-stiffness response was observed over a range of 4–8 mm distraction for the 12 specimens tested, with an average tension of 80 N associated with 8 mm distraction. Average values of carpal height ratio, revised carpal height ratio, and carpal height index were found to be poor indicators of distraction, owing to their high variability between specimens.
