[ XXXX of the femur neck in children and adolescents. Apropos of 12 cases].

@entity1136 @entity5 @entity117 @entity10545 @entity158
Specific characters of the @entity10545 as a @entity5 are well known. We report twelve cases of femoral neck localisation. Delays in diagnosis of six months to one year after the onset of symptoms are quite common. Chronic or recurrent @entity158 is localised in the inguinal area with a projection to the leg and to the knee. The @entity158 was relieved by @entity117 in six cases only. X ray of the pelvis antero-posterior showed the @entity5 , but did not always show the lucent image with the surrounding sclerotic area that is well observed with tomography. The scintigraphy with @entity1136 99 is perhaps more sensitive as a way of diagnosis. The lesion is the place of intensive uptake. Although the surgical excision "in block" and the replacing of bone graft and material of osteosynthesis gave positive results, many technical problems are present during the intervention because of the important cortical reaction and bone densification. In six cases, peroperative X Ray and histology did not give diagnosis.
