One hundred and one tibiotalar arthrodeses were performed using a single surgical technique that has not been previously reported. The average follow-up was ten years (range, two to twenty-five years). The rate of pseudarthrosis was 5 per cent, four to five times less than in other recent large reports. Pseudarthrosis occurred only in patients with a sensory deficit. Secure fusion was radiographically documented in 95 per cent and the functional clinical result was good to excellent in 90 per cent. The ideal fusion position was found to be neutral or slight equinus angulation, and varus-valgus angulation equal to that of the contralateral side. More than 7 degrees of varus angulation of the heel was associated with symptomatic lateral metatarsalgia in all feet in which it occurred. Radiographic measurement documented an average 85 per cent (11-degree) increase in postoperative tarsal motion. Neither symptoms nor function correlated with the degree of tarsal hypermobility.
采用一种此前未报道过的单一手术技术进行了101例胫距关节融合术。平均随访时间为10年（范围为2至25年）。假关节发生率为5%，比其他近期大型报告中的发生率低四至五倍。假关节仅发生在有感觉缺陷的患者中。影像学显示95%实现了牢固融合，90%的患者临床功能结果为良好至优秀。理想的融合位置为中立位或轻度马蹄内翻角，内外翻角度与对侧相等。足跟内翻角度超过7度与所有出现该情况的足部的症状性外侧跖痛相关。影像学测量显示术后跗骨活动平均增加85%（11度）。症状和功能均与跗骨活动过度程度无关。
