METHODS: A search in PubMed and Google using the terms congenital malalignment of the great toenail, disappearing nail bed, and lateral nail deviation was performed. Of the 53 photographs found in a total of 35 articles, 23 were disqualified due to low picture resolution or poor angle. The remaining 30 photographs were evaluated. Pure nail malalignment with associated dystrophy and DNB was found in 22 of 30 photographs. Four of 30 cases demonstrated pure deviation of the distal phalanx, with nail dystrophy but minimal DNB. The remaining 4 cases demonstrated a combination of toe deviation and nail unit deviation with varying degrees of DNB.
CONCLUSIONS: DNB was associated with all forms of pure CMGT. Moreover, a variant of malalignment of the distal phalanx was noted in 8 photographs. This has potential implications for further studies and treatment to correct secondary complications.
方法:在PubMed和Google中使用大脚趾甲的先天性不对准术语进行搜索,消失的甲床,并进行了横向指甲偏移。在总共35篇文章中发现的53张照片中,23由于图片分辨率低或角度差而被取消资格。对剩余的30张照片进行评价。在30张照片中的22张发现了与营养不良和DNB相关的纯指甲不对齐。30例中有4例显示出远端指骨的纯偏离,与指甲营养不良,但最小的DNB。其余4例表现为脚趾偏差和指甲单位偏差的组合,并伴有不同程度的DNB。
结论:DNB与所有形式的纯CMGT相关。此外,在8张照片中注意到远端指骨的排列不良。这对于进一步的研究和治疗以纠正继发性并发症具有潜在的意义。
