Purpose: There are controversies regarding the measurement method and normal
range on stress radiographs for evaluation of chronic lateral ankle instability. This
study was performed to research radiologic values measured in normal Korean
adults and to analyze differences by age and gender. Materials and Methods: Sixty
Korean adults (20 in twenties, 20 in thirties, 20 in forties) were recruited and each of
these three groups was comprised of 10 males and 10 females. The selection criteria
of candidate were no history of ankle injury and no evidence of ankle instability.
Radiologic measurement of talar tilt and anterior talar translation was performed
through stress radiographs using Telos, and repeated two times by three
researchers. Results: Ankle stress radiographs had good intraobserver reproducibility
and interobserver reliability. Talar tilt and anterior talar translation were average 3.7°
and 3.5mm in his twenties, 5.1° and 4.2mm in her tw enties, 3.9° and 4.1mm in his
thirties, 4.8° and 3.8mm in her thirties, 3.4° and 3.6mm in his forties, 4.5° and 4.1mm
in her forties. There was no significant difference in talar tilt and anterior talar
translation by age. But, there was significant difference in talar tilt by gender.
Conclusion: On ankle stress radiographs in normal Korean, talar tilt and anterior talar
translation were average 3.7° and 3.7mm in male, 4. 8° and 4mm in female. It seems
to be a good reference for radiologic evaluation and for treatment of chronic ankle
instability.
