Legg-Calve Perthes Disease Overview and Management

Legg-Calve Perthes disease (LCP) is a hip condition affecting

children aged 4-10 years

Legg-Calve Perthes disease (LCP) is characterized by

spontaneous, temporary disruption of blood supply to the femoral head.

What can happen if a child with LCP is not protected from weight-bearing forces?

The femoral head is likely to collapse, leading to avascular necrosis.

Which gender is more commonly affected by Legg-Calve Perthes disease?

Males are more commonly affected.

What percentage of Legg-Calve Perthes disease cases are bilateral?

15% of cases are bilateral.

How does Legg-Calve Perthes disease compare to Slipped Capital Femoral Epiphysis (SCFE)?

LCP is less common than SCFE.

Which of the following is NOT a symptom that children with LCP might report?

limited in adduction

What is the immediate intervention for a child suspected of having LCP?

Refer out immediately and make them non-weight bearing until assessed.

How are mild cases of LCP treated?

non-operatively w/

observations, serial imaging, and limiting impact activities (like running)

What interventions are used for moderate cases of LCP?

partial weight bearing

casting or bracing to assist w/ femoral remodeling.

What treatment may be required for severe cases of LCP or older children?

may require surgery

INC risk for hip degenerative disease later in life.

What role does physical therapy play in the treatment of LCP?

often required to assist with hip ROM

What are the long-term outcomes for children with LCP?

even for those requiring surgery, generally good.

What age range is most commonly affected by LCP?

4-10 years

What hip motion is often limited in LCP?

Internal rotation

Children with LCP may rest their hip in what position?

External rotation

What is the primary reason for avoiding weight-bearing in LCP?

Prevent collapse of femoral head
