Subungual exostosis is a relatively uncommon benign bone tumour that mostly affects the toes of young people and can be a source of significant impact on health-related quality of life. Treatment consists of marginal excision and meticulous wound closure. We presented a case of subungual exostosis in the hallux of a young Caucasian girl. Once diagnosed, the lesion was completely excised leaving a sizable defect in the nail bed and skin folds. A pedicled vacuum assisted closure (VAC) device was used postoperatively in an attempt to minimise the tissue deficit. At 1-year follow-up, the nail had regrown and tissue reformed producing an optimal functional and cosmetic result with no recurrence. Postoperative wound complications in the setting of subungual exostosis are significant and a great variability exists in their appropriate management. We presented the novel use of the VAC device in the successful management of subungual exostosis.
甲下外生骨疣是一种相对罕见的良性骨肿瘤，主要影响年轻人的脚趾，并且可能对健康相关生活质量产生重大影响。治疗方法包括边缘切除和细致的伤口闭合。我们报告了一例年轻白种女孩拇趾甲下外生骨疣的病例。一旦确诊，病变被完全切除，在甲床和皮肤皱襞处留下了一个较大的缺损。术后使用带蒂负压封闭引流（VAC）装置，试图尽量减少组织缺损。在1年的随访中，指甲重新生长，组织重塑，产生了最佳的功能和美容效果，且无复发。甲下外生骨疣情况下的术后伤口并发症很严重，其适当的处理方式存在很大差异。我们展示了VAC装置在成功治疗甲下外生骨疣中的新应用。
