A very uncommon pattern of thumb duplication consists of an ulnar-side floating thumb and a radial-side distally hypoplastic thumb.
We report the case of a 15-month-old child with this type of thumb duplication on his right hand treated with an on-top-plasty technique. The ulnar-side segment was pedicled and transferred to the lateral thumb, which was distally resected.
A well-aligned and widely mobile thumb with a wide first web and an excellent cosmetic appearance was exhibited 10 years after surgery.
On-top-plasty technique might be amenable to reconstruct certain atypical thumb duplications.
一种非常罕见的拇指重复畸形模式包括尺侧漂浮拇指和桡侧远侧发育不全拇指。
我们报告了一名15个月大儿童右手患有这种类型拇指重复畸形并采用叠盖成形术治疗的病例。尺侧部分带蒂并转移至拇指外侧，远侧部分予以切除。
术后10年，拇指排列良好且活动广泛，第一蹼宽阔，外观极佳。
叠盖成形术可能适用于重建某些非典型拇指重复畸形。
