The distinction between primary and secondary syndactyly is made on the basis of their relation to the morphogenesis. The latter is associated with antecedent malformation which results in subsequent refusion of parts. Based on these considerations, a practical classification is suggested. The management of the various types of malformations is considered in relation to the complexity of the structures involved. Certain deformities require very early treatment in order to permit prehensile function to the developing infant, or to release the impaired part. It is desirable to complete all surgery before the child enters school. The severe complex syndactyly could rarely be solved by one operation. Normal appearance and function are rarely attained and, with growth, newer problems of imbalance and contracture appear. While rehabilitation of the hand is seldom needed for the children with cutaneous syndactyly, the severe deformities associated with complex syndactyly often require supervision in order to regain the potential function and simple dynamic splints are very helpful.
原发性并指和继发性并指的区分是基于它们与形态发生的关系。后者与先前的畸形有关，这会导致随后部分的重新融合。基于这些考虑，提出了一种实用的分类方法。根据所涉及结构的复杂程度来考虑各种类型畸形的处理。某些畸形需要非常早期的治疗，以便发育中的婴儿能够具备抓握功能，或者松解受损部位。希望在孩子入学前完成所有手术。严重复杂的并指很少能通过一次手术解决。很少能获得正常的外观和功能，而且随着生长，会出现新的失衡和挛缩问题。虽然皮肤并指的儿童很少需要手部康复，但与复杂并指相关的严重畸形通常需要进行监督，以恢复潜在功能，简单的动力夹板非常有帮助。
