Two men and one woman (age 31, 36 and 45 years) felt a painful pop in the left middle, right middle and right index finger during sport-related activities (2 sport climbing and 1 judo). Clinical examination found a painful flexor tendon in zone 2 but no function deficit specific to the flexor digitorum superficialis (FDS) tendon. MRI and ultrasonography revealed a complete disruption of the radial FDS tendon slip only, which was found retracted between the A2 and A3 pulleys. All flexor tendon pulleys remained intact. Conservative and functional treatment resulted in unrestricted normal function and return to sport. Disruption of one FDS tendon slip is a differential diagnosis for a popping incident in the finger, which is typically associated with a closed flexor tendon pulley injury.
两名男性和一名女性（年龄分别为31岁、36岁和45岁）在与运动相关的活动（2次攀岩和1次柔道）中，左手食指中部、右手食指中部和右手食指出现疼痛性弹响。临床检查发现2区屈肌腱疼痛，但没有特定的指浅屈肌（FDS）肌腱功能缺陷。磁共振成像（MRI）和超声检查仅显示桡侧FDS肌腱束完全断裂，发现其在A2和A3滑车之间回缩。所有屈肌腱滑车均保持完整。保守和功能治疗导致功能正常且不受限制，并可恢复运动。一根FDS肌腱束断裂是手指弹响事件的鉴别诊断之一，通常与闭合性屈肌腱滑车损伤有关。
