MRI STUDY OF ANKLE: TALAR LENGTH AND MALLEOLAR INDEX
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2014, Vol 1, Issue 10
Abstract
Ankle instability has been correlated with many factors such as peroneal muscle weakness, varus hind foot. However knowledge of the measurement of malleolar index and maximum talar length and their correlation with each other may draw better picture of ankle instability in routine MRI studies of ankle joint. Since very minimal studies are reported till date, this study was taken up. This study was done on 30 MRI films of adult individual ankles. Malleolar index ranged from 8.8º to 32º. Mean malleolar index was found to be 18.46º. Maximum talar length ranged from 46mm to 63mm. Mean talar length was found to be 52.31mm. There was positive correlation between malleolar index and talar length as per Pearson’s correlation test with R value being 0.97. Thus, talar length may be correlated with the fibular position. An ankle mortise with a more posteriorly positioned fibula has less structural stability and is more susceptible to sprain.
