We report on a 38-year-old woman suffering from painful trigger finger. Contrary to the expected intraoperative finding of a simple stenosing pulley and ganglion cyst on a thickened flexor tendon sheath, we found fibrotic cords between an abnormal ulnar sesamoid bone at the fifth finger and the A1-pulley to be responsible for distortion of the tendon sheath and a consecutive "klicking"-phenomenon. A coherence between sesamoid bones and trigger finger has repeatedly been found on the thumb but there is no such description regarding the long fingers.
我们报告了一位38岁患有扳机指疼痛的女性病例。与预期的术中发现（即增厚的屈肌腱鞘上单纯的狭窄滑车和腱鞘囊肿）相反，我们发现第五指异常的尺侧籽骨与A1滑车之间的纤维条索是导致腱鞘变形和连续“咔嗒”现象的原因。籽骨与扳机指之间的关联在拇指上已被多次发现，但关于其他手指尚无此类描述。
