A study to determine the degree of normal talar tilt in individuals with no history of ankle injuries was performed on 404 ankles of 202 midshipmen at the U.S. Naval Academy. Manual inversion stress roentgenograms were used to test this group of young healthy adults, most of whom were males. Of the 404 ankles tested, only 39 (9.7%) had any measurable talar tilt and only 7 ankles (1.7%) had a tilt over 5 degrees. Normal talar tilt does not range to 23 degrees. A normal ankle in a healthy young adult with no history of trauma has a small probability of having any talar tilt. When stress roentgenograms are used to evaluate a fresh lateral ankle ligament sprain in this type of individual, there is a very high probability that talar tilt over 5 degrees would represent significant injury to one or more of the lateral supporting structures.
一项针对美国海军学院202名海军学员的404个踝关节进行的研究，旨在确定无踝关节损伤史个体的正常距骨倾斜度。采用手动内翻应力X线片对这组年轻健康的成年人（大多数为男性）进行测试。在接受测试的404个踝关节中，只有39个（9.7%）有任何可测量的距骨倾斜，只有7个踝关节（1.7%）的倾斜度超过5度。正常距骨倾斜度不会达到23度。没有创伤史的健康年轻成年人的正常踝关节出现距骨倾斜的可能性很小。当使用应力X线片评估这类个体的新鲜外侧踝关节韧带扭伤时，距骨倾斜超过5度极有可能表示外侧一个或多个支撑结构受到了严重损伤。
