T. Hashimoto et S. Inokuchi, A KINEMATIC STUDY OF ANKLE JOINT INSTABILITY DUE TO RUPTURE OF THE LATERAL LIGAMENTS, Foot & ankle international, 18(11), 1997, pp. 729-734
Kinematic analysis of patients who have ruptured the ligaments of the
ankle joint was performed to evaluate the function of those ligaments.
Ten patients with ruptured lateral collateral ligaments and 10 normal
volunteers were examined. Patients' ages ranged from 17 to 29, averag
ing 20.9 years old, We performed kinematic evaluation by a three-dimen
sional optical analytic technique using surface markers. According to
our results, the ankles with lateral ligament injury abnormally pronat
ed and rotated externally at the time of heel strike and abnormally su
pinated and rotated internally during the acceleration phase.
