Legg-Calvé-Perthes (LCP)

Legg-Calvé-Perthes (LCP) is a condition that occurs when the blood supply to the femoral head is temporarily interrupted, resulting in osteonecrosis (bone death) of the femoral head. This can lead to damage to the bone tissue, loss of bone structure, and ultimately loss of the hip joint.

LCP most commonly affects children between 4 and 10 years old, and is more common in boys than in girls. The cause of the reduced blood flow is not yet fully understood, but it may be related to a combination of genetic and environmental factors.

How does LCP develop?

In LCP, there is a temporary reduction in blood supply to the femoral head. Because the bone no longer receives oxygen and nutrients, it dies and becomes weaker. Over time, the body tries to regenerate the bone, but during this process, the shape of the femoral head may change.

The exact cause is unknown, but possible factors include:

• genetic predisposition
• blood clotting problems
• trauma or injury to the hip
• growth disorders

With Legg-Calvé-Perthes, individuals typically experience pain when:

• Getting in or out of a car
• Putting on and taking off shoes and socks
• Standing up after prolonged sitting
• Deep hip flexion
• Hip rotations
• Impact sports, deep bending movements, and changes of direction
• Walking
• Squatting
• …

With the right treatment and self-care measures, symptoms can often be well managed, and a quality active life can be maintained. If discomfort persists, an injection may be given, or surgery may be necessary.

If LCP is advanced, a total hip arthroplasty may be necessary. Depending on the morphology of the hip joint, a preparatory surgery (relative lengthening of the femoral neck) may first be required before performing total hip arthroplasty.

We will discuss with you which treatment option is most suitable based on your specific situation and needs.
