Legg-Calvé-Perthes disease (or Perthes disease) is a rare condition in children in which the ball-shaped head of the thigh bone, referred to as the femoral head, loses its blood supply. As a result, the femoral head collapses. The body will absorb the dead bone cells and eventually replace them with new bone cells.

Perthes disease is a rare childhood condition that affects the hip. It occurs when the blood supply to the rounded head of the femur

Is Legg-Calvé-Perthes disease life threatening?

Legg-Calve-Perthes disease, also known as Perthes disease, is a disorder of the hip in young children that usually occurs between the ages of 4 and 10. The hip is made up of the femoral head — the “ball,” which is the upper part of the femur — and the acetabulum — the “cup” that fits around the femoral head.

What is the goal of Perthes?

The first goal is to regain hip motion and keep the ball as round as possible in order to maximize the function of the hip into adulthood.

What is the name of the condition where the ball-shaped head of the thigh bone loses its blood supply

Legg-Calvé-Per thes disease ( or Perthes disease) is a rare condition in children in which the ball-shaped head of the thigh bone, referred to as the femoral head, loses its blood supply. As a result, the femoral head collapses. Over time, the body absorbs the dead bone and replaces it with new bone, but this process can lead to flattening ...

What is the goal of treatment for femoral head deformity?

Your opinion or preference. The goal of treatment is to preserve the roundness of the femoral head and to prevent deformity while the condition runs its course.

What is the best treatment for a femoral head?

Medications, such as ibuprofen. Casting or bracing (to hold the femoral head in the hip socket, permit limited joint movement, and allow the femur to remold itself into a round shape again) Bony surgery on the femur (thigh bone) or the socket to contain the femoral head in the hip socket.

How long does the phase 1 of a femoral head last?

Portions of the bone turn into dead tissue. The ball of the thigh bone becomes less round in appearance on X-rays. This phase can last from several months up to 1 year.

What causes a hip to be stiff and painful?

Over time, the body absorbs the dead bone and replaces it with new bone, but this process can lead to flattening of the ball. As a result, Legg-Calvé-Perthes disease can cause the hip joint to become painful and stiff for a period of time. Legg-Calvé-Perthe s disease goes through four phases of changes that affect the head of the femur.

How long does a femoral ball last?

This phase can last from 1 year to 3 years. Phase 3 - Reossification phase. During this phase, the bone of the ball starts to harden and the femoral head begins to remodel into a round shape again. This phase lasts for 1 year to 3 years. Phase 4 - Healing phase.

How rare is Legg-Calve-Perthes disease?

Legg-Calve-Perthes disease affects less than 1 percent of the general population and is therefore very rare , but it is four times more common in boys than girls.

What is the name of the disease that affects the femoral head?

What is Legg-Calve-Perthes Disease? Legg-Calve-Perthes disease, also known as Perthes disease, is a disorder of the hip in young children that usually occurs between the ages of 4 and 10. The hip is made up of the femoral head — the “ball,” which is the upper part of the femur — and the acetabulum — the “cup” that fits around the femoral head.

Why is it important to move the hip?

This is because the cartilage on the femoral head depends on the liquid in the joint, called the synovial fluid, for its nutrition. Moving the hip helps to supply the cartilage with this fluid.

What happens when the femoral head collapses?

The femoral head then “necroses,” or loses blood supply , which weakens the bone and can lead to multiple fractures. Next, the bone is taken up by the body, or resorbed, which can lead to a complete collapse of the femoral head. The blood supply does eventually return and the bone will re-form, or re-ossify.

Why does blood clot in the femoral head?

The reasons for this, however, are unclear. It might be due to trauma that damages the blood vessels or to disorders that cause the blood to clot and clog up the veins.

Why is it important to keep the head in the hip socket?

It is also important to keep the head in the hip socket so that when the bone does re-form, it has the best and most round shape possible. Sometimes, the child’s hip becomes stiff and may need help to keep the ball in the cup. Your doctor may recommend a period of casting, bracing and/or physical therapy to help achieve this.
