The diseases of the hip in growth can cause groin pain or pain radiating into the thigh and / or knee, refuse to gait and support the body's own weight. There are many causes for these symptoms and the diagnosis is not always easy. Transient synovitis, one of the most common causes of hip pain in children, must be differentiated from septic arthritis. Other causes may be disease specific to hip growth as Perthes disease, upper femur epifisiolisis and bone fractures by avulsion of tendon insertions in the pelvis.
The hip of the child from the standpoint of morphology is not like a "miniature adult hip”. (see section "Normal Hip"). The main differences that we find are:
|figure 1A: normal radiograph of the pelvis of a child aged 13, observe the cartilage growth still perfectly open marked with red lines|
|figure 1B: Photograph of child hipbone (8 years) where one observes the acetabular cartilage triradiate in its external face - acetabulum and internal|
|figure 2a: progressive development of cores of ossification of the proximal femur from 4 months to 6 years. Note how the head of the femur and the trochanter ossify from a mold of cartilage, which is separated by neck joint growth cartilage.|
|figure 2b: figure 2b in a 12 year old child the trochanter and the femoral head are already completely ossified.
The growth cartilage of the femoral head is common to the greater trochanter and remains active, only closing after puberty.
It is believed that the non-separation of cartilage growth of the trochanter and the femoral head may lead to an "oval"head of the femur as it happens in "cam" deformity ". (see section "What is femoroacetabular impingement?" )
figura 3. Layout blood perfusion of the femoral head in children. There is no passage of blood to the femoral head due to the presence of growth cartilage. In all hip preservation techniques, including arthroscopy, this knowledge is critical to the orthopedist.
