Early symptoms of avascular necrosis of the femoral head in children?

summary

Osteonecrosis of the femoral head in children is also called epiphyseal chondritis, aseptic necrosis of the femoral head or flat hip. It is a common and unexplained chondropathy in children. It usually occurs in children aged 2 to 12 years old. It begins with degeneration or necrosis, then regenerates or re calcifies, and finally necrosis of the femoral head. The disease began to show knee hip joint pain, walking inconvenience or lameness, the affected hip can not bend and extend, adduction. At this time, if there is no timely diagnosis and treatment, delay the course of disease, resulting in femoral head flattening "flat hip", may lead to disability. Therefore, early diagnosis and early treatment are very important. Now let me talk to you about the early symptoms of osteonecrosis of the femoral head in children?.

Early symptoms of avascular necrosis of the femoral head in children?

First: the onset is slow, the course of disease is long, intermittent claudication and knee, hip pain, pain often radiates to the inner thigh and knee, pain can be aggravated with the activity, relieve after rest.

Second: some cases have mild or no symptoms in the early stage, and some cases have a history of trauma. They may have acute attack after injury, with obvious pain and claudication. When the knee joint is painful, there are tenderness points when pressing around the hip joint by hand.

Third: let the child supine position, the affected limb up, less than 45 degrees, hip pain. Do "4" experiment: put the affected limb "4" shape on the contralateral thigh, press the knee down, when pressing, the hip joint has pain. In the late stage, the symptoms gradually relieved and disappeared, the joint activity was normal or the residual abduction and internal rotation were limited, the greater trochanter was prominent, sometimes there were hip flexion or adductor contracture, muscle atrophy of thigh and leg, limb shortening and other deformities.

matters needing attention

(1) Early bed rest and abduction of affected limbs by percutaneous traction are conducive to the regression of synovitis and relieve muscle spasm and pain（ 2) Some cases can be fixed with plaster in abduction and internal rotation position（ 3) The walking bracket was fixed in abduction and internal rotation position.
