Microsurgical revascularization has proved to be a useful method in managing the ring avulsion injury where both neurovascular bundles are damaged with only partial skin avulsion. Representative cases are used to illustrate guidelines for a practical classification for helping to decide the optimal method of treatment of acute ring avulsion injuries in light of digital revascularization techniques. Nine ring fingers were successfully revascularized of 24 acute ring avulsion injuries reviewed. Sensibility recovery was good and a functional range of motion obtained. No patient who has had his ring finger revascularized has requested its amputation because of appearance, painful neuromas, stiffness, or cold intolerance. Complete amputations, especially proximal to the superficialis insertion, and complete degloving injuries of the ring finger are usually best managed by surgical amputation of the digit.
显微外科血管重建术已被证明是治疗环形撕脱伤的一种有效方法，这种损伤中神经血管束均受损且仅有部分皮肤撕脱。通过典型病例来说明实用分类的指导原则，以根据手指血管重建技术来帮助确定急性环形撕脱伤的最佳治疗方法。在回顾的24例急性环形撕脱伤中，9例环指成功实现了血管重建。感觉恢复良好，获得了功能性活动范围。没有因外观、疼痛性神经瘤、僵硬或不耐寒而要求截除已进行血管重建的环指的患者。完全离断伤，尤其是在指浅屈肌附着点近端的离断伤，以及环指的完全脱套伤，通常最好通过手术截指来处理。
