We experienced two cases of flexor tendons rupture after triamcinolone acetate (TA) injection for trigger finger. A 45-year-old man underwent injection of 40 mg of TA and 1 mL of 1% lidocaine solution into his little finger. While playing golf 3 months after the injection, he heard a popping sound, and was unable to flex it. A 57-year-old female nurse had undergone injection of 40 mg of TA and 1 mL of 1% lidocaine solution into her thumb twice at a 2-month interval. Two months after the second injection, she was unable to flex it. Both cases had high concentrated TA injection at trigger digits. The present and previous cases illustrate that when TA is injected into trigger digits, the dose should be low, the safety interval should be long, and refuse injection into the tendon proper.
我们遇到了两例在使用醋酸曲安奈德（TA）注射治疗扳机指后发生屈肌腱断裂的病例。一名45岁男性在其小指注射了40mg TA和1mL 1%利多卡因溶液。注射后3个月打高尔夫球时，他听到一声爆裂声，随后手指无法弯曲。一名57岁的女护士每隔2个月在其拇指注射40mg TA和1mL 1%利多卡因溶液两次。第二次注射后2个月，她的拇指无法弯曲。这两例均在扳机指处进行了高浓度TA注射。目前及之前的病例表明，当将TA注射到扳机指时，剂量应低，安全间隔应长，并且应避免注入肌腱本身。
