PURPOSE
The ankle joint and surrounding subtalar joint have several tendons in close proximity. This study was performed to investigate the concurrent adjacent tissue involvement on MRI findings when the surgical treatment is considered for an acute inflammatory arthritis of the ankle joint.
METHODS
Consecutive patients with acute inflammatory ankle arthritis who visited the emergency room and underwent MRI were included. After interobserver reliability testing of MRI findings, adjacent tissue involvement in the acute inflammatory ankle arthritis were evaluated including flexor hallucis longus (FHL), flexor digitorum longus (FDL), tibialis posterior (TP), peroneus longus (PL), peroneus brevis (PB), extensor digitorum longus (EDL), tibialis anterior (Tib Ant), extensor hallucis longus (EHL), subtalar joint, talus, tibia, and calcaneus.
RESULTS
Twenty-five patients (mean age 57.8 years; 16 males and nine females) were included. Of the 25 patients, 23 showed FHL involvement, 21 FDL, 21 TP, 15 PL, 15 PB, three EDL, 21 subtalar joint, six talus, six tibia, and five calcaneus on MR images. No Tib Ant or EHL involvement was observed on MR findings in acute inflammatory ankle arthritis.
CONCLUSIONS
Patients with acute inflammatory ankle arthritis showed frequent concomitant surrounding tissue involvement on MRI, which included FHL, FDL, TP, and subtalar joint. This needs to be considered when surgical drainage is planned for acute inflammatory ankle arthritis.
目的
踝关节和周围的跗骨间关节有几个肌腱非常接近。本研究旨在探讨当考虑手术治疗急性踝关节炎症性关节炎时，MRI 发现的同时相邻组织受累情况。
方法
纳入因急性炎性踝关节关节炎就诊急诊并接受 MRI 检查的连续患者。在 MRI 检查结果的观察者间可靠性测试后，评估急性炎性踝关节关节炎的相邻组织受累情况，包括：踇长屈肌腱（FHL）、趾长屈肌腱（FDL）、胫后肌（TP）、腓骨长肌（PL）、腓骨短肌（PB）、趾长伸肌（EDL）、胫骨前肌（Tib Ant）、踇长伸肌（EHL）、跗骨间关节、距骨、胫骨和跟骨。
结果
共纳入 25 例患者（平均年龄 57.8 岁；男性 16 例，女性 9 例）。25 例患者中，23 例 FHL 受累，21 例 FDL，21 例 TP，15 例 PL，15 例 PB，3 例 EDL，21 例跗骨间关节，6 例距骨，6 例胫骨，5 例跟骨在 MRI 图像上受累。在急性炎性踝关节关节炎的 MRI 结果中未观察到胫骨前肌或踇长伸肌受累。
结论
急性炎性踝关节关节炎患者在 MRI 上显示出频繁的伴随周围组织受累，包括 FHL、FDL、TP 和跗骨间关节。当计划对急性炎性踝关节关节炎进行手术引流时，需要考虑到这一点。
