Forty fractured calcanei (13 without and 27 with involvement of the joint) were examined by CT and the angle of the hind foot measured. Following a typical compression fracture there is a negative calcaneus-valgus angle, i.e. varus deformity of the tuberosity fragment. The sustentaculum angle is increased. There are changes in the talo-calcaneal and calcaneo-cuboidal angles. The length ratio of calcaneus to talus is reduced. Reproducible measurements make it possible to compare the results of operative correction and of changes in shape following conservative treatment, e.g. during weight-bearing.
对40例跟骨骨折患者（13例关节未受累，27例关节受累）进行了CT检查并测量了后足角度。典型的压缩性骨折后，跟骨外翻角为负，即结节骨折块内翻畸形。载距突角增大。距跟关节角和跟骰关节角有变化。跟骨与距骨的长度比降低。可重复的测量结果使得比较手术矫正结果以及保守治疗（如负重期间）后形状变化成为可能。
