Perthes disease is the disruption of blood flow to the femoral head in children.
Perthes disease is a rare paediatric disorder in which the blood flow to the femoral head (the ball of the hip joint) is temporarily disturbed, resulting in bone cell death. This disease, known as avascular necrosis, weakens the bone and can cause deformity if left untreated. The actual cause is unknown; however, it primarily affects children aged four to ten, with boys being more afflicted than girls.
Symptoms include limping, hip or groin pain, stiffness, and a limited range of motion. In certain situations, pain may spread to the knees or thighs. Physical examinations and imaging tests, such as X-rays and MRI scans, are used to diagnose bone abnormalities.
The treatment focuses on maintaining hip function and fostering appropriate bone regrowth. Mild cases may require rest, physical therapy, and anti-inflammatory drugs, whereas severe cases may necessitate bracing or surgery to keep the joints aligned. The long-term prognosis is dependent on the child's age and the degree of the bone injury, but early care can reduce difficulties. Parents should seek medical assistance for their children's prolonged limping or hip pain to guarantee adequate therapy and avoid long-term joint problems.
