Over a nine-year period, 20 feet with persistently symptomatic talocalcaneal coalition were treated by resection of the bar. The 17 patients were all under 16 years of age. Excellent or good long-term results were achieved in the ten feet in which preoperative coronal CT had shown that the area of coalition measured 50% or less of the area of the posterior facet of the calcaneum. In these feet heel valgus was less than 16 degrees and there were no radiographic signs of arthritis of the posterior talocalcaneal joint. Talar beaking was present in 70% of these feet but it did not impair the clinical result. Fair or poor results were observed in the ten feet in which preoperative CT had shown the area of relative coalition to be greater than 50%. In these feet, heel valgus was greater than 16 degrees and most had narrowing of the posterior talocalcaneal joint and impingement of the lateral process of the talus on the calcaneum.
在九年的时间里，对20例有持续性症状的距下关节联合患者进行了骨桥切除术。这17例患者均未满16岁。术前冠状位CT显示联合区域占跟骨后关节面面积50%或以下的10只足获得了优良的长期效果。在这些足中，足跟外翻小于16度，距下后关节无影像学关节炎表现。这些足中有70%存在距骨喙，但这并未影响临床效果。术前CT显示相对联合区域大于50%的10只足观察到一般或较差的效果。在这些足中，足跟外翻大于16度，大多数距下后关节变窄，距骨外侧突撞击跟骨。
