摘　　要：目的:探讨先天性多指畸形的X线表现及临床分型意义,总结经验并尝试性对分类方法进行完善。方法:以Wassel分类法和Stelling-Twrek分类法为依据,回顾性分析85例先天性多指畸形(91只病手)的X线表现及临床资料,主要观察先天性多指畸形的发病性别、类型、部位、特点及X线表现,依据本组病例X线表现尝试性对分类方法进行完善。结果:术前X线全部诊断正确,先天性多指畸形多为单手发病(92.94%,79/85)且好发于右手(左、右手比例约为0.65∶1),男性多见,男女比例约为3.7∶1;轴前型较轴后型多见(轴前、轴后发病比例约为9.1∶1),Wassel和Stelling-Twrek分类法中以Ⅳ型最为常见,约占轴前型发病率的51.22%(42/82),但约4.88%(4/82)的多指畸形无法分类。结论:先天性多指畸形较为常见,术前X线检查不仅可以进行分类而且有助于临床制定手术方式,但临床分类方法亦有待改进之处。Objective：To investigate the radiographic manifestations and their significance for clinical classification of congenital polydactyly,in order to provide improvement of its classification. Methods：Wassel and Stelling-Twrek classifica- tion was used as the basis of study,the radiographic manifestations and clinical materials of 85 cases with congenital poly- dactyly （a total of 91 sick hands） were recruited,mainly to study the incidence of gender, type, location, characteristics and radiographic find＇ings of congenital polytactyly. According to the radiographic manifestations, suggestion for further im- provement of classification was attempted. Results：All patients had been correctly diagnosed by radiography before surgery. Congenital polytactyly occurred at one-hand accounts for 92.94% （79/85 cases）, mainly the right hand （the ratio of inci- dence of left and right hands was approximately 0.65 ： 1）. The incidence of males was higher than that of females with the ratio as 3.7 ： 1. Preaxial polydaetyly was more common than Postaxial polydactyly, with the ratio being 9.1 ： 1. According to Wassel and Stelling-Twrek classification,the most common type was Type IV with the incidence being approximately 51. 22% （42/82 cases） in preaxial polydactyly patients. However,there were about 4.88% （4/82 cases） polydacty!y patients which could not be classified yet. Conclusion：Congenital polydactyly is frequently seen. Preoperative radiographic examina- tion is helpful not only for the classification but also for surgical planning. Yet improvement of clinical classification needs further study.
