At what age does the epiphyseal plate close?

At what age does the epiphyseal plate close?

This replacement is known as epiphyseal closure or growth plate fusion. Complete fusion happens on average between ages 15 and 20 for girls (with the most common being 15–18 years for girls) and between 17 and 24 for boys (with the most common being 18–22 years for boys).

What would happen if the epiphyseal plate was damaged in childhood?

If the growth plate has been shifted, shattered or crushed, the risk of limb deformity is greater. Age of the child. Younger children have more years of growth ahead of them, so if the growth plate is permanently damaged, there is more chance of deformity developing.

At what age is the epiphyseal plate active?

When kids are done growing, the growth plates harden into solid bone. This happens in girls around ages 13–15 and in boys around ages 15–17.

How does the epiphyseal plate allow for growth in bone length in children?

Bone Growth Bones grow in length at the epiphyseal plate by a process that is similar to endochondral ossification. The cartilage in the region of the epiphyseal plate next to the epiphysis continues to grow by mitosis. The chondrocytes, in the region next to the diaphysis, age and degenerate.

How do you know if your growth plate is closed?

On an x-ray, growth plates look like dark lines at the ends of the bones. At the end of growth, when the cartilage completely hardens into bone, the dark line will no longer be visible on an x-ray. At that point, growth plates are considered closed.

What age does the growth plate close?

Growth plates usually close near the end of puberty. For girls, this usually is when they’re 13–15; for boys, it’s when they’re 15–17.

What happens when a child breaks their growth plate?

A growth plate fracture, if not treated promptly, can result in a leg or arm that’s crooked or shorter than another. Bearing weight on uneven legs causes hip and knee problems. With rapid and competent treatment, most growth plate fractures heal without complications.

Why would a doctor be worried about a child who broke a long bone close to the epiphyseal plate?

Complications. One problem is something your child’s doctor may call “growth arrest.” This is when the injury causes their bone to stop growing. They could end up with one leg or arm shorter than the other.

Why is the epiphyseal growth plate important?

The epiphyseal growth plate is the main site of longitudinal growth of the long bones. At this site, cartilage is formed by the proliferation and hypertrophy of cells and synthesis of the typical extracellular matrix. The formed cartilage is then calcified, degraded, and replaced by osseous tissue.

Do you stop growing if you break your growth plate?

If the growth plate is damaged by a fracture or another injury, the bone may stop growing. This serious problem is called a growth arrest.

What is the maximum age for a girl to grow taller?

Girls usually stop growing and reach adult height by 14 or 15 years old, or a couple years after menstruation begins. Learn more about growth in girls, what to expect when it happens, and when you may want to call your child’s pediatrician.

How long does it take for a growth plate injury to heal?

How long does it take to recover from a growth plate injury? With proper care, the vast majority of growth plate injuries heal without complication. This will typically involve a few weeks or months in a cast, depending on the location and severity of the injury.
