Carpal tunnel release (CTR) is an effective procedure used in open, endoscopic, or ultrasound-guided methods. The complications are rare but potentially devasting. Most complications come from errors related to intraoperative technique, especially in the minimally invasive approach. An understanding of the "safe zones" is essential to perform percutaneous CTR safely. This article reviews the anatomy of safe zones and the ultrasound-guided CTR (UCTR) techniques in an attempt to prevent intraoperative complications. In strict accordance with the concepts of safe zones, UCTR is an effective and reliable procedure. Substantial experience for ultrasound-guided injection and surgery is required.

经皮腕管释放的安全区。

腕管松解术 (CTR) 是一种用于开放式、内窥镜或超声引导方法的有效程序。并发症很少见，但可能具有破坏性。大多数并发症来自与术中技术相关的错误，尤其是在微创方法中。了解“安全区”对于安全地进行经皮 CTR 至关重要。本文回顾了安全区的解剖结构和超声引导 CTR (UCTR) 技术，以期预防术中并发症。严格按照安全区的概念，UCTR 是一种有效且可靠的程序。需要有丰富的超声引导注射和手术经验。
