Abstract
|
|
|
Purpose:The aim of this study was to investigate the usefulness of mortise angle and fibular length measured in radiologic findings in predicting the ankle stability.
Material and Methods : One hundred cases fifty cases were randomly selected volunteers with normal ankle function and the other fifty cases were randomly selected patients whose ankle were treated in our hospital and who were followed for over 1 years with good results. A specific experimental fixture were made to get the even AP and lateral view and objective stress view.
Results: The mortise angle and fibular length was not statistically significant to the degree of talar tilt angle under valgus or varus stress and that of displacement under anterior or posterior stress.
Conclusions: The mortise angle and fibular length was not the objective predicting factors on the ankle stability. Maintenance of constrained talus in dynamic status is most important factors in determining the ankle stability.
