Direct measurement of ligament length in the wrist is difficult due to constrained space and short length of many ligaments. No prior studies have reported measurements of ligament length between the carpal bones of the wrist. In this presentation, we have combined high precision motion analysis of the carpal bones, subsequent manual digitization of the ligament attachment regions, and a simulated ligament wrapping model, to generate predictions of carpal ligaments’ length and implied strain during wrist motion.
