Question

Fracture at which site will affect the longitudinal growth of the bone?

• A. Epiphyseal plate
• B. Epiphysis
• C. Metaphysis
• D. Diaphysis

Hint:

Injuries to the epiphyseal plate can disrupt normal bone growth and lead to permanent deformities or growth abnormalities.

Answer 1

The Correct Option is A

To determine which site fracture will affect the longitudinal growth of a bone, we must understand the roles of different bone structures:

• Epiphyseal Plate: This is also known as the growth plate. It is a hyaline cartilage plate in the metaphysis at the ends of long bones. Growth in the length of the bone occurs here during childhood and adolescence. Fractures in this area can disrupt the lengthening process, leading to growth disturbances.
• Epiphysis: This is the rounded end of a long bone, which participates in joint formation. While injuries here can affect joint function, they do not typically impact the longitudinal growth of the bone.
• Metaphysis: This is the narrow portion of a long bone between the epiphysis and the diaphysis. While it supports and bears weight, it does not play a primary role in the growth of the bone's length.
• Diaphysis: This is the shaft or central part of a long bone. Its primary role is to support weight and provide leverage. Fractures here do not affect the lengthwise growth of the bone.

Therefore, fractures at the Epiphyseal Plate will affect the longitudinal growth of the bone since this area is responsible for lengthening during growth periods.
