Final answer:
An epiphyseal fracture affects the growth plate in a child's bone and can lead to premature stop in bone growth, potentially resulting in short stature if not properly treated.
Step-by-step explanation:
A epiphyseal fracture occurs in a growth section of a child's bone, which may prematurely stop growth if not properly treated. The epiphyseal plate, also known as the growth plate, is found in children and adolescents; it is where new bone is added as the child grows. An injury to this plate can affect the bone's growth and development. It's essential to treat such fractures correctly to prevent potential complications such as a short stature or abnormal bone development.
