Ankle fractures, clinical and experimental studies. [free PhD. thesis]
The role of talar rotation in supination external rotation injuries is examined in a cadaver study. A clear medial space widening of more than 2 mm on the mortise radiograph is considered to represent an ‘unstable’ fracture displacement that requires surgical reduction and internal fixation. Experimental studies revealed that a lateral talar dislocation of only 1 mm reduces the contact area between talus and tibia in such a way that the strongly increased peak loads will damage the carilage, which might finally result in symptomatic osteoarthritis. It is assumed that tibio-talar joint congruity is almost solely determined by the deltoid ligament > from Christian Donken (2013). All rights reserved to the author and Radboud Universiteit Nijmegen.
