Central polydactyly of the foot is rare, with few reports on surgical methods and treatment indications. In this study, based on the experience of central polydactyly in our department, we will consider morphological classification and describe our treatment plan.
In this retrospective study, 11 patients (11 digits) with central polydactyly were identified among 136 patients of polydactyly of the foot (2009-2018). They were classified according to morphologic characteristics: type I, the duplicated digits are independent of each other; type II, digits of the same size are duplicated; and type III, digits of different sizes are duplicated.
In morphologic classification, there were 4 cases of type II and 7 cases of type III, but there was no case of type I. For type II, surgery was performed using the Bilhaut-Cloquet (BC) procedure in 2 patients, bone-removing flap (flap) method in 1 patient, and simple ablation in 1 patient. For type III, surgery was performed using the BC procedure in 1 patient, flap method in 3 patients, simple ablation in 2 patients, and ligation in 1 patient with floating type.
In order to obtain good cosmetic results in digits of morphologic classifications type II and III, it is necessary to select the surgical approach with careful consideration of every feature.
足部中央多趾较为罕见，目前鲜有关于手术方法和治疗适应证的报道。本研究基于我科中央多趾的经验，对其进行形态学分类，并描述治疗方案。
回顾性分析 2009 年至 2018 年间收治的 136 例足部多趾患者（200 足）中 11 例（11 趾）中央多趾患者的临床资料，根据形态学特征进行分类：Ⅰ型，两个重复趾完全独立；Ⅱ型，两个重复趾大小相同；Ⅲ型，两个重复趾大小不同。
形态学分类中，Ⅱ型 4 例，Ⅲ型 7 例，未见Ⅰ型。Ⅱ型中，2 例行 Bilhaut-Cloquet（BC）手术，1 例行骨瓣（皮瓣）法，1 例行单纯切除。Ⅲ型中，1 例行 BC 手术，3 例行皮瓣法，2 例行单纯切除，1 例行浮趾结扎。
为了获得形态学分类为Ⅱ型和Ⅲ型的重复趾良好的美容效果，需要根据每个特征仔细选择手术方法。
