BACKGROUND: Pincer nail deformity is a rare but clinically significant toenail malformation characterized by excessive transverse curvature of the nail plate, often causing pain and functional impairment. Current treatments include surgical and conservative treatments, while existing orthotic devices may cause varying degrees of damage to the nail.
OBJECTIVE: The purpose of this study is to evaluate the efficacy of a memory metal wire (originally used in dentistry) in three subtypes of pincer nail deformity.
METHODS: A total of 45 patients with various subtypes (Tile-Shaped: 28 cases, Trumpet-Shaped: 10 cases, Fan-Shaped: 7 cases) underwent orthotic treatment. Data collection included demographic questionnaires, Visual Analog Scale (VAS) for pain, and self-reported esthetic satisfaction scores. Pre- and postoperative surveys were analyzed to assess treatment outcomes.
RESULTS: Postoperative improvements in VAS scores and self-reported esthetic satisfaction were statistically significant compared to preoperative values (p < 0.05), and no significant differences were observed among subtypes (p > 0.05).
CONCLUSION: The modified pincer nail deformity correction technique using cotton packing, dental resin, and nickel-titanium wire demonstrates universal applicability and favorable therapeutic efficacy across various subtypes, offering a promising clinical approach for pincer nail deformity correction.
