Avascular necrosis (AVN) following rotational ankle fractures is most commonly described in the talus; however, it can also occur in the tibial plafond. These sequelae of ankle fractures are rarely described in the literature. Diagnosis of AVN is best confirmed with MRI of the involved extremity. Treatment options range from conservative treatments such as observation and limited weight-bearing to surgical management including percutaneous drilling, ankle arthrodesis, and total ankle arthroplasty. More research is needed to further identify patients at high risk for developing these sequelae of ankle fractures and to aid in the treatment and surgical decision-making process.
旋转性踝关节骨折后发生的缺血性坏死（AVN）最常见于距骨；然而，它也可能发生在胫骨平台。踝关节骨折的这些后遗症在文献中很少被描述。AVN的诊断最好通过受累肢体的MRI来确认。治疗选择范围从保守治疗，如观察和限制负重，到手术管理，包括经皮钻孔、踝关节融合术和全踝关节置换术。需要更多的研究来进一步确定发生这些踝关节骨折后遗症的高危患者，并有助于治疗和手术决策过程。
