Abstract

PURPOSE: The aim of this study was to analyze radiological change of Kager's triangle in patients with retrocalcaneal disorders. MATERIALS AND METHODS: Areas of Kager's triangle and calcaneus were calculated with Heron's Formula. Average of area ratio (area of Kager's triangle / area of calcaneus) was calculated for comparison and analysis, according to disease activity and aging process. One-tailed Z-test was done with the average of area ratio. RESULTS: Average of area ratio (area of Kager's trianlge / area of calcaneous) tends to decrease according to aging process and disease existence. CONCLUSION: Because area of Kager's triangle in patients with retrocalcaneal disorders tends to change according to disease activity and aging process, we should consider clinical correlation between the anatomical structure of Kager's triangle and retrocalcaneal symptoms.
