Pincer nail deformity is an excessive transverse curvature of the nail plate. It often causes severe pain and reduces the patient's quality of life. Various surgical techniques have been reported for pincer nail deformity, but no studies have reported the use of artificial dermis to resolve the dead space on both sides of the distal phalanx after the deformed nail bed is elevated. We describe our new surgical method placing artificial dermis in these dead spaces, and we provide the results of our evaluation of the method's effectiveness.
We examined the cases of the patients who underwent surgical treatment using artificial dermis for pincer nail deformity at our hospital between April 1, 2020, and March 31, 2024. The patients' information was retrospectively reviewed from the medical records. In the surgery, we placed artificial dermis in the dead space on both sides of the distal phalanx. The change in nail curvature was evaluated using the height index (HI).
A total of 19 toes of 11 patients were included. Postoperatively, the mean HI value was significantly improved from 64.8% to 12.9% (p<0.05). All 11 patients were relieved of the pain. No early postoperative complications and no recurrences were observed in the patients.
Our new method of placing artificial dermis in the dead space on both sides of the distal phalanx is a simple and effective treatment for pincer nail deformity.
钳形甲畸形是指甲板过度横向弯曲。它常导致严重疼痛并降低患者生活质量。已有多种手术技术用于治疗钳形甲畸形，但尚无研究报道在抬高畸形甲床后使用人工真皮来解决远节指骨两侧的死腔问题。我们描述了在这些死腔中放置人工真皮的新手术方法，并提供了该方法有效性评估的结果。
我们检查了2020年4月1日至2024年3月31日期间在我院接受使用人工真皮治疗钳形甲畸形手术的患者病例。从病历中回顾性审查患者信息。在手术中，我们在远节指骨两侧的死腔中放置人工真皮。使用高度指数（HI）评估指甲曲率的变化。
共纳入11例患者的19个趾。术后，平均HI值从64.8%显著改善至12.9%（p<0.05）。所有11例患者的疼痛均得到缓解。患者未观察到早期术后并发症和复发情况。
我们在远节指骨两侧死腔中放置人工真皮的新方法是治疗钳形甲畸形的一种简单有效的方法。
