Chondrodystrophia (now: Achondroplasia) formerly believed to be a uniform disease rather is an entity comprising up till now at least ten radiologically differing types. Definite diagnosis of these types can only be made radiologically although certain clinical features are of additional help. For practical purpose a schematic representation of these types is given, based upon the classification of congenital osteochondrodysplasias by the ESPR (European Society of Pediatric Radiology, Rome, 1969). It emphasizes the characteristic radiological signs and describes the typical changes in body proportions. In a second part the single diseases are discussed according to the scheme with their radiological differential diagnosis and their prominent changes in the skeletal system. Some examples are given for possibly associated malformations and final prognosis.
软骨发育不良（现称：软骨发育不全）过去被认为是一种单一疾病，而实际上是一个实体，目前至少包括十种放射学表现不同的类型。尽管某些临床特征有辅助作用，但这些类型的明确诊断只能通过放射学检查来进行。出于实际目的，基于欧洲儿科放射学会（罗马，1969年）对先天性骨软骨发育不良的分类，给出了这些类型的示意图。它强调了特征性的放射学征象，并描述了身体比例的典型变化。在第二部分中，根据该方案讨论了单一疾病，包括它们的放射学鉴别诊断以及骨骼系统的突出变化。给出了一些可能相关的畸形和最终预后的例子。
