Comparison of Radiologic Parameters between Weight Bearing Affected Both Ankle and Single Ankle in Ankle Exam

Abstract

This study was performed to analyze the results of radiologic parameters compared both leg weight bearing position to single leg weight bearing position in ankle osteoarthritis.Between January 2016 and June 2016, 25 patients (50 ankles) who visited our Hospital to treat ankle pain. In radiographic assessment, We masured tibial anterior surface angle(TAS), tibial medial malleolar angle(TMM), talar tilting angle(TT), joint space width(JSW), tibiotalar joint space, fibulotalar joint space of ankle as radiologic parameters.On the right leg of the both leg weight bearing position, TAS was 87.24°, TT was 6.44°, TMM was 26.76°, fibulotalar joint space was 0.98mm. Right leg of the single leg weight bearing position, TAS was 88.93°, TT was 2.41°, TMM was 19.77°, fibulotalar joint space was 1.6mm. And then, on the left leg of the both leg weight bearing position, TAS was 87.25°, TT was 5.71°, TMM was 23.92°, fibulotalar joint space was 1.22 mm and left leg of the single weight bearing position, TAS was 88.75, TT was 3.19°, TMM 21.45°, fibulotalar joint space was 1.22 mm. There are unsimilarity between measure values of TAS and tibiotalar joint space.As the result of test of weight bearing ankle study, it would be more exact to examine to measure one side in the first time rather than both to conclude on accurate measurement.
