Ankle joint distraction (AJD) avoids the potential complications associated with ankle fusion or total ankle replacement (TAR) in patients with advanced ankle osteoarthritis (OA). AJD could a tenable option to ankle fusion or TAR.
A review has been performed on the role of AJD in advanced OA of the ankle. The exploration machine was MedLine. The keywords utilized were: joint distraction ankle. Three hundred and eleven articles were found. Of the above-mentioned, only 14 were chosen and analyzed because they were rigorously focused on the issue and the question of this paper.
The types of articles published until now have a poor level of evidence (levels III and IV). The overall number of patients managed until now by way of AJD is 249. The published mean follow-up is very variable, from 1 year to 12 years.
The rate of good outcomes ranged between 73% and 91%. The percentage of failure (final ankle arthrodesis or TAR) ranged between 6.2% and 44%. A minimum of 5.8 mm of distraction gap must be achieved. Ankle function after AJD deteriorates over time. Putting together ankle movement and distraction will result in an early and maintained profitable influence on outcome.
踝关节撑开术（AJD）可避免晚期踝关节骨关节炎（OA）患者进行踝关节融合术或全踝关节置换术（TAR）时出现的潜在并发症。AJD对于踝关节融合术或TAR而言可能是一个可行的选择。
对AJD在晚期踝关节OA中的作用进行了一项综述。检索工具为MedLine。使用的关键词为：踝关节撑开术。共找到311篇文章。其中，仅14篇文章被选中并进行分析，因为它们严格聚焦于本文的问题。
迄今为止发表的文章证据水平较低（III级和IV级）。迄今为止通过AJD治疗的患者总数为249例。已发表的平均随访时间差异很大，从1年到12年不等。
良好结果的发生率在73%至91%之间。失败率（最终踝关节融合术或TAR）在6.2%至44%之间。必须实现至少5.8毫米的撑开间隙。AJD后的踝关节功能会随时间恶化。将踝关节活动与撑开相结合将对结果产生早期且持续的有益影响。
