Trigger finger causes pain and a persistent functional limitation of the hand, which can lead to permanent blockage of the flexor tendon. Ultrasonography-guided percutaneous release has been widely reported as a successful technique for trigger finger involving the A1 pulley. This article describes for the first time the use of this technique in an unusual location, the A3 pulley of the fifth finger. A 71-year-old patient presented with a 3-month history of pain and blockage in the fifth finger of the right hand and was diagnosed with a grade III trigger finger, according to the Froimson scale. We performed an ultrasonography-guided percutaneous release technique on the A3 pulley to release the flexor tendon of the fifth finger. Ultrasonography-guided percutaneous polectomy to treat trigger finger in the A1 pulley is an effective alternative treatment to surgery and even has certain advantages over it. The anatomical similarity between the A1 and A3 pulleys was the key factor that supported the use of this technique in this clinical case. Based on past experience in similar cases, we conclude that ultrasonography-guided percutaneous polectomy of the A3 pulley of the fifth finger was a surgical technique which could lead to a satisfactory outcome in the treatment of this condition.
扳机指会引起手部疼痛和持续的功能受限，严重时可导致屈肌腱永久性粘连。超声引导下经皮松解术已被广泛报道为治疗 A1 滑车扳机指的有效技术。本文首次描述了该技术在一个不常见部位（第五指 A3 滑车）的应用。一名 71 岁女性患者，右手第五指出现 3 个月的疼痛和活动受限，根据 Froimson 分级诊断为 3 级扳机指。我们对第五指 A3 滑车行超声引导下经皮松解术，以释放屈肌腱。超声引导下经皮 A1 滑车切开术治疗扳机指是一种有效的手术替代疗法，甚至在某些方面优于手术。A1 和 A3 滑车的解剖相似性是支持该技术在该临床病例中应用的关键因素。基于过去类似病例的经验，我们得出结论，超声引导下第五指 A3 滑车经皮切开术是一种治疗该疾病的手术技术，可以获得满意的效果。
