Distal intersection tenosynovitis (DIT) is a rare and recently described condition that affects the extensor pollicis longus (EPL), extensor carpi radialis brevis (ECRB), and longus (ECRL). Based on surgical observations, this study aimed to provide new insights into its physiopathology. This was a retrospective study of all patients who underwent surgery for DIT at our institution from 2015 to 2024. Five patients were included in the study. Wrist joint issues clearly explained the occurrence of DIT in three cases. Tendon lesions were observed either on the extensor carpi radialis brevis or extensor pollicis longus. : These additional data complement the existing literature, which primarily focuses on the anatomical mechanisms of DIT without fully explaining its causes. Our observations suggest that wrist joint or bone disorders may play a significant role in its occurrence. Lesions in different tendons suggest the involvement of distinct pathological mechanisms.
远端交叉腱鞘炎（DIT）是一种罕见且近期才被描述的疾病，它会影响拇长伸肌（EPL）、桡侧腕短伸肌（ECRB）和桡侧腕长伸肌（ECRL）。基于手术观察，本研究旨在为其病理生理学提供新的见解。这是一项对2015年至2024年在我们机构接受DIT手术的所有患者的回顾性研究。该研究纳入了五名患者。在三例病例中，腕关节问题清楚地解释了DIT的发生。在桡侧腕短伸肌或拇长伸肌上观察到了肌腱病变。这些额外的数据补充了现有文献，现有文献主要关注DIT的解剖学机制，但没有充分解释其病因。我们的观察结果表明，腕关节或骨骼疾病可能在其发生中起重要作用。不同肌腱的病变表明涉及不同的病理机制。
