Legg-Calvé-Perthes (leg-cal-VAY-PER-teez) disease is a hip disorder that affects
bone growth at the top part of the thighbone and the hip joint. It usually occurs
in kids between 4 and 8 years of age, and is more common in boys.
More to Know
The cause of LCP is not known, but it sometimes runs in families. Children who
are around secondhand smoke, were born very small, or have certain blood problems
also are more likely to develop it.
Symptoms can include limping, hip pain, and knee pain. The pain usually comes
on slowly and may be mild.
When LCP is suspected, the doctor will do a physical exam and order X-rays. Early stages
of LCP do not always show up on an X-ray, so an MRI
or other imaging study also might be done.
Keep in Mind
Treatment depends on the child's age, amount of pain, and other
factors. Decreasing activity can sometimes ease pain, but some kids will need a brace,
cast, or crutches to keep them from putting weight on the leg. Some must rest the
leg completely, and severe cases may require surgery. Many kids with LCP need physical
therapy to help them improve the range of motion in the hip and leg muscles.
