Imaging examinations are a fundamental part of assessing chronic lateral ankle instability (CLAI). Plain radiographs are used in the initial examination, whereas stress radiographs can be requested to actively search for instability. Ultrasonography (US) and Magnetic Resonance Imaging (MRI) allow direct visualization of ligamentous structures, with the advantage of dynamic evaluation for US, and assessment of associated lesions and intra-articular abnormalities for MRI, which plays an essential role in surgical planning. This article reviews imaging methods to diagnose and follow up on CLAI, along with illustrative cases and an algorithmic approach.
影像学检查是评估慢性外侧踝关节不稳定（CLAI）的基本组成部分。平片检查用于初始检查，而应力位片可用于主动寻找不稳定。超声（US）和磁共振成像（MRI）允许直接观察韧带结构，US 具有动态评估的优势，MRI 可评估相关病变和关节内异常，在手术计划中起着重要作用。本文回顾了用于诊断和随访 CLAI 的影像学方法，同时提供了病例说明和算法流程。
