Ankle impingement refers to a chronic painful mechanical limitation of ankle motion caused by soft-tissue or osseous abnormality affecting the tibiotalar joint or extraarticular soft tissues. Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. Impingement syndromes at the tibiotalar joint can be subdivided into anterior, anterolateral, anteromedial, posterior or posteromedial. Extraarticular impingement can consist of talocalcaneal or subfibular impingement. Impingement syndromes are just one possible etiology of persistent ankle pain, and although the diagnosis is often made or suspected clinically, the radiologist might be the first person to raise the possibility of the diagnosis or be called upon to provide support for the clinically suspected diagnosis. In this article I review the etiology, imaging findings and current treatment associated with these conditions.

脚踝和后足的撞击综合征。

脚踝撞击是指由于软组织或骨异常影响胫距骨关节或关节外软组织而引起的踝关节运动的慢性疼痛性机械性限制。撞击可能与先前的单个创伤事件或反复的微创伤有关，通常在具有解剖学倾向的青少年中。胫骨距关节的撞击综合征可分为前，前外侧，前内侧，后或后内侧。关节外撞击可包括突或腓骨下撞击。撞击综合征只是持续性脚踝疼痛的一种可能病因，尽管诊断通常是在临床上做出或怀疑的，放射科医生可能是第一个提出诊断可能性的人，或者被要求为临床怀疑的诊断提供支持。在本文中，我将回顾与这些疾病相关的病因，影像学发现和当前治疗方法。
