Cartilaginous Joints - Synchondroses

Synchondroses are a temporary type of cartilaginous joint that are seen at epiphyseal plates (growth plates) during development. They allow for growth of long bones by flexibly joining the epiphysis, or end, of a growing long bone to the diaphysis, or shaft, of a long bone. This type of joint is made of hyaline cartilage that is eventually replaced by bone after growth is completed (synchondroses become synostoses). You may have heard that children are particularly susceptible to breaking bones at their growth plates. This makes sense because that region of the bone is actually hyaline cartilage, which has little tensile strength. Synchondroses are also found at the union between the first rib and the sternum.
