The most common injury to the dorsal distal finger is a subungual hematoma. Relief of pain is promptly achieved by draining the hematoma. If a heated paper clip is used, however, the underlying fluid may be seared and the hole plugged. Local anesthetic block followed by puncture with an 18-guage needle is advocated. When nail avulsion occurs, the free-floating proximal portion should be removed so that it will not serve as an irritant or hide any underlying pathology.
手指远端背侧最常见的损伤是甲下血肿。通过引流血肿可迅速缓解疼痛。然而，如果使用加热的回形针，可能会烧灼下方的液体并堵塞孔洞。建议先进行局部麻醉阻滞，然后用18号针穿刺。当指甲撕脱发生时，应去除游离漂浮的近端部分，以免其成为刺激物或掩盖任何潜在病变。
