There is no consensus on the best treatment for pincer nail deformity. We developed a novel procedure that uses double wires to treat pincer nail deformity on the great toe. This study aimed to describe this technique for pincer nail deformity treatment and present the long-term findings/observations. After injecting a local anesthetic, a mini router was used to make holes on both sides of the nail plate edge, and the wire was inserted in two places, one proximal and the other distal to the great toenail. The wire was removed when it moved to the tip of the great toe as the nail grew. Patients who underwent this method were evaluated retrospectively from 2014 to 2020. Patients with less than 24 months of follow-up were excluded. If pain occurred again, it was deemed as a recurrence. A total of 27 patients (36 toes, mean age: 69.5 years) were evaluated. In all cases, the pain disappeared 1 week after the procedure. In the correction period (mean 2.7 months), six toes had complications (nail break, four toes and nail hold pain, two toes), while recurrence occurred in four toes within 2 years. Curvature (nail tip height/width of nail tip × 100%) improved significantly up to 1-year post-procedure (37.7 ± 14.4%, p < 0.05) as compared to pre-correction (53.8 ± 24.7%). The procedure time was short (approximately 10 minutes), and the treatment was completed with a single procedure. In addition, the recurrence rate was low.
对于钳状甲畸形，目前尚无最佳治疗方法的共识。我们开发了一种使用双丝治疗大脚趾钳状甲畸形的新方法。本研究旨在描述这种治疗钳状甲畸形的技术，并介绍长期发现/观察结果。在局部麻醉注射后，使用微型路由器在指甲板边缘的两侧打孔，将丝线插入指甲近端和远端的两个位置。随着指甲的生长，当丝线移动到大脚趾的尖端时，就将其取出。从 2014 年到 2020 年，对接受这种方法的患者进行了回顾性评估。排除了随访时间少于 24 个月的患者。如果再次出现疼痛，则视为复发。共有 27 名患者（36 个脚趾，平均年龄：69.5 岁）接受了评估。所有病例术后 1 周疼痛消失。在矫正期（平均 2.7 个月），有 6 个脚趾出现并发症（指甲断裂，4 个脚趾和指甲疼痛，2 个脚趾），而在 2 年内有 4 个脚趾复发。与矫正前（53.8±24.7%）相比，术后 1 年时（37.7±14.4%），弯曲度（指甲尖端高度/指甲尖端宽度×100%）显著改善（p<0.05）。手术时间短（约 10 分钟），且仅需一次手术即可完成治疗。此外，复发率较低。
