Trigger finger (TF) is one of the most common causes of hand disability. Immobilization of TF with a joint-blocking orthosis has been demonstrated to effectively relieve pain and improve function. The efficacy of steroid injections for TF varies based on the number of affected digits and the clinical severity of the condition. Up to three repeat steroid injections are effective in most patients. When conservative interventions are unsuccessful, open surgical release of the A1 pulley effectively alleviates the subjective and objective manifestations of TF and currently remains the benchmark procedure for addressing TF. Although several studies have emerged suggesting that a percutaneous approach may result in improved outcomes, this technique demands a learning curve that may predispose patients to higher risk of procedure-related complications. There is no role for preoperative antibiotics in patients who undergo elective soft-tissue procedures of the hand. WALANT anesthesia has gained popularity because it has been associated with improved patient outcomes and a clear cost savings; however, proper patient selection is critical. Similar to other soft-tissue hand procedures, TF surgery rarely necessitates a postoperative opioid prescription.
扳机指(Trigger Finger,TF)是手部残疾最常见的原因之一。关节阻断矫形器固定 TF 已被证明可有效缓解疼痛和改善功能。类固醇注射治疗 TF 的疗效因受影响的手指数量和疾病的临床严重程度而异。大多数患者中,多达三次重复类固醇注射是有效的。当保守治疗无效时,切开手术松解 A1 滑车可有效缓解 TF 的主观和客观表现,目前仍然是解决 TF 的基准手术。尽管有几项研究表明经皮方法可能会带来更好的效果,但这种技术需要一个学习曲线,可能会使患者面临更高的与手术相关的并发症风险。对于接受手部软组织择期手术的患者,术前使用抗生素没有作用。WALANT 麻醉因其与改善患者结局和明显的成本节约相关而受到欢迎;然而,正确的患者选择至关重要。与其他手部软组织手术类似,TF 手术很少需要术后开具阿片类药物处方。
