Anterior ankle impingement results from an impingement of the ankle joint by a soft tissue or osteophyte formation at the anterior aspect of the distal tibia and talar neck. It often occurs secondary to direct trauma (impaction force) or repetitive ankle dorsiflexion (repetitive impaction and traction force). Chronic ankle pain, swelling, and limitation of ankle dorsiflexion are common complaints. Imaging is valuable for diagnosis of the bony impingement but not for the soft tissue impingement, which is based on clinical findings. MR imaging and MR arthrography are helpful in doubtful diagnoses and the identification of associated injuries. Recommended methods for initial management include rest, physical therapy, and shoe modification. If nonoperative treatment fails, arthroscopic bony or soft tissue debridement both offer significant symptomatic relief with long-term positive outcomes in cases that have no significant arthritic change, associated ligament laxity, and chondral lesion.
前踝撞击症是由于胫骨远端和距骨颈前侧的软组织或骨赘形成对踝关节的撞击所致。它通常继发于直接创伤（撞击力）或反复的踝关节背屈（反复的撞击和牵引）。慢性踝关节疼痛、肿胀和踝关节背屈受限是常见的主诉。影像学检查对骨撞击症的诊断有价值，但对软组织撞击症的诊断没有价值，后者基于临床发现。MR 成像和 MR 关节造影术有助于诊断疑难病例和发现相关损伤。初始治疗的推荐方法包括休息、物理治疗和鞋具修改。如果非手术治疗失败，关节镜下骨或软组织清理均能提供显著的症状缓解，并且在没有明显关节炎改变、相关韧带松弛和软骨损伤的情况下，长期结果为阳性。
