Ankle joint distraction has been shown to be a viable alternative to ankle arthrodesis or ankle replacement. The authors' approach to ankle joint preservation includes articulated ankle joint distraction, resection of blocking osteophytes, release of muscle and joint contractures, and realignment osseous ankle procedures. In a previous study that used this technique, 78% of patients maintained their ankle range of motion and had none to occasional moderate pain that could be managed generally with nonsteroid anti-inflammatory drugs alone. The rationale as to why joint distraction is successful is largely unknown. Therefore, the purpose of this study was to evaluate pre- and postoperative ankle MRI scans of patients who underwent hinged ankle joint distraction with external fixation.
踝关节撑开术已被证明是踝关节融合术或踝关节置换术的一种可行替代方法。作者保留踝关节的方法包括使用关节式踝关节撑开、切除阻挡性骨赘、松解肌肉和关节挛缩以及进行踝关节骨性结构的重新排列手术。在之前一项使用该技术的研究中，78%的患者保持了踝关节活动范围，且仅有轻度至偶尔的中度疼痛，一般仅使用非甾体抗炎药即可控制。关节撑开术成功的原因在很大程度上尚不清楚。因此，本研究的目的是评估接受带外固定的铰链式踝关节撑开术患者术前和术后的踝关节磁共振成像扫描结果。
