We have developed a method of measuring anterior displacement of the calcaneus on the talus in instability of the subtalar joint and have used the technique to demonstrate anterior instability in 50 patients (72 feet) showing a positive drawer sign. The angle of the posterior facet of the talus was also measured to assess the bony configuration. Our patients with subtalar joint instability could be divided into three categories. The first group had a history of trauma leading to ankle instability (26 cases), the second showed generalised joint laxity (10 cases) and the third were young females with a history of chronic stress on the foot and a poor bony block (14 cases). Satisfactory results were obtained by treating the instability with a brace or by reconstruction of the interosseous talocalcaneal ligament.
我们已经开发出一种测量距下关节不稳定时跟骨相对于距骨向前移位的方法，并运用该技术在50例（72足）出现阳性抽屉试验体征的患者中证实了前侧不稳定。同时还测量了距骨后关节面的角度以评估骨结构。我们的距下关节不稳定患者可分为三类。第一组有导致踝关节不稳定的外伤史（26例），第二组表现为全身关节松弛（10例），第三组是有足部慢性应力史且骨块不佳的年轻女性（14例）。通过使用支具治疗不稳定或重建距跟骨间韧带，获得了满意的结果。
