Os calcaneus angles in dry bones of Turkish population

Abstract

Purpose: The aim of this study was to evaluate calcaneus angles in dry bones belonging to Turkish population. Materials and Methods: Dry calcaneal bones which age and sex were unknown belonging to Cukurova University Faculty of Medicine were used in this study. The photographs of the bones were taken under fixed light and distance, positioned like lateral direct graph, the Böhler (BA) and Gissane (GA) angles were measured according to the reference points using the digital design program (SketchUp 2016). Calculation sensitivity was 1/10°. Angle value distrubitons and left right relations were examined. After the measurements minimum-maximum, median and standart deviation values were obtained. Results: Total of 67 dry bones were clasified as left and right. The average BA was measured as (minimum-maximum); 29.68°±4.71° (20.00°-39.80°) on the right side and 31.54°±4.88° (20.20°-41.20°) on the left side. GA average was measured as (minimum-maximum); 102.96°±5.25° (93.70°-114.5°) on the right side, 103.89°±7.14° (93.10°-120.4°) on the left side. For both angles no significant difference was found between left and right calcaneus. Conclusions: Calcaneus angles may differ between races and populations. These angular values are important in determining calcaneus fractures. Base values of these angles are especially important in determining the baseline values which will be useful in practice. In literature the risk of fractures (especially displaced fractures) increases as the Böhler Angle and Gissane Angle approach the lower limits. Therefore, values obtained in this study will contribute establishing reference values in Turkish population.
