What is COXA Plana disease?

What is COXA Plana disease?

Coxa plana is a disease of the previously normal hip joint in which the bony nucleus of the femoral head becomes necrotic. The dead bone is gradually replaced by the usual stages of bone repair. During this process there is usually some flattening of the normally spherical femoral head.

What are the signs and symptoms of Legg Perthes disease?

Signs and symptoms of Legg-Calve-Perthes disease include:

• Limping.
• Pain or stiffness in the hip, groin, thigh or knee.
• Limited range of motion of the hip joint.
• Pain that worsens with activity and improves with rest.

How many people in the world have Perthes?

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 are the stages of Perthes disease?

The Perthes stages include: onset stage; fragmentation stage; reconstitution stage; residual stage. Each stage of Perthes disease has key indicators, which signifies the progression of the disease through the various stages.

Which is the third radiographic stage of Legg-Calve-Perthes disease?

The disease follows distinct radiographic stages described by Waldenström: 1) initial – with ischemia-induced sclerosis; 2) fragmentation – when absorption, fibrovascular invasion, physeal changes, and cartilaginous metaplasia lend a lytic appearance to the epiphysis and metaphysis, with variable collapse; 3) re- …

What is coxa vara and coxa Valga?

Coxa valga is a deformity due to an increase in the angle between the head and neck of the femur and its shaft (normally 135 degrees). Coxa vara is the opposite: a decreased angle between the head and neck of the femur and its shaft. Coxa vara is usually indicated when the angle is less than 120 degrees.

How is Perthes diagnosed?

How is Perthes disease diagnosed? If your child is experiencing symptoms of Perthes disease, your healthcare provider will order an X-ray. X-rays are a common way to confirm a diagnosis. Your provider may also order additional studies, such as an MRI, to see how far the disease may have progressed.

Is Perthes disease genetic?

Legg-Calvé-Perthes disease is usually not caused by genetic factors. The cause in these cases is unknown. In a small percentage of cases, mutations in the COL2A1 gene cause the bone abnormalities characteristic of Legg-Calvé-Perthes disease.

Is Perthes genetic?

Legg-Calve-Perthes disease (LCPD) is usually not caused by genetic factors (thus is usually not inherited ), but there are some cases where LCPD affects more than one family member. In a small percentage of these familial cases, changes or mutations in the COL2A1 gene have been found to cause LCPD.

Are you born with Perthes disease?

Perthes disease is a rare childhood condition affecting the hip joint.

How is Perthes disease diagnosed?

What is femoral epiphysis?

The end of the femur that connects with the hip consists of a “ball” (called the femoral head). The ball fits inside of a “cup” that is made up of the pelvic bones and is known as the acetabulum. During growth, the end of the head is known as the epiphysis and is connected to the rest of the femur by the growth plate.
