\n\t\t\t\t\t\t\t\t\t

Legg-Calv\u00e9-Perthes disease is one of the most important hip joint disorders in children. It occurs as a result of a temporary reduction in blood supply to the head of the femur, leading to gradual breakdown of the bone, followed by reformation over a prolonged period that may last months to years.
Early diagnosis and careful follow-up are essential to prevent permanent deformity of the hip joint.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Condition Overview<\/strong>

Perthes disease occurs when blood flow to the femoral head is temporarily reduced, leading to temporary weakening of the bone followed by changes in its shape.
It most commonly affects children between the ages of 4 and 10 and is more frequent in boys.<\/p>



<\/p>

Symptoms That Require Parental Attention<\/strong>

\u2022 Pain in the hip or knee joint.
\u2022 Limping or an abnormal walking pattern without a clear cause.
\u2022 Limited hip joint movement, especially when moving the leg outward.
\u2022 Mild stiffness in the morning or after physical activity.
\u2022 Pain after playing or running.
\u2022 In some cases, an obvious limp without pain.<\/p>



<\/p>

Causes of Perthes Disease<\/strong>

The exact cause is still unknown, but possible contributing factors include:

\u2022 Temporary reduction in blood supply to the femoral head.
\u2022 Mild genetic factors.
\u2022 Delayed bone growth in some children.
\u2022 High physical activity in certain age groups.
\u2022 Poor development of blood vessels supplying the joint.<\/p>



<\/p>

How Is It Diagnosed?<\/strong>

\u2022 Clinical examination to assess gait and range of motion.
\u2022 X-rays of the pelvis to determine disease stage and bone damage.
\u2022 MRI in early stages before X-ray changes appear.
\u2022 Assessment of leg length discrepancy.<\/p>



<\/p>

Stages of Perthes Disease<\/strong>

1. Ischemic stage: reduced blood supply.
2. Fragmentation stage: breakdown of the femoral head.
3. Re-ossification stage: new bone formation.
4. Healing stage: final bone shape restoration.

Early diagnosis leads to better outcomes.<\/p>



<\/p>

Treatment Options<\/strong>

<\/p>

Conservative Treatment (Most Common):<\/strong>

\u2022 Physical therapy to improve hip mobility.
\u2022 Flexibility exercises to prevent stiffness.
\u2022 Pain relievers when needed.
\u2022 Activity modification to reduce joint stress.
\u2022 Braces or special devices in selected cases.<\/p>



<\/p>

Surgical Treatment:<\/strong>

Surgery may be considered when:

\u2022 Diagnosis occurs after age 8 with severe changes.
\u2022 Significant loss of joint motion.
\u2022 Severe femoral head collapse.
\u2022 Failure of conservative treatment.

The goal is to improve femoral head coverage during bone healing.<\/p>



<\/p>

Prognosis and Recovery Duration<\/strong>

\u2022 The condition may take 1\u20133 years to complete all stages.
\u2022 Younger children usually have better outcomes.
\u2022 Regular follow-up is essential to prevent deformity or leg length difference.<\/p>



<\/p>

Advice for Parents<\/strong>

\u2022 Do not ignore any limp, even if mild.
\u2022 Encourage swimming and cycling instead of running and jumping.
\u2022 Commit to physical therapy sessions.
\u2022 Maintain regular imaging follow-up.
\u2022 Seek medical advice if pain or limping worsens.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
