[Arthrography in pathology of the hip in older children].

Arthrography of the hip was performed in outpatients on 25 children aged 5 to 14 years, using a supra-trochanteric latero-external puncture approach. Data obtained supplied anatomical details indispensable for the decision to operate or not, particularly in certain congenital dislocations or in Legg-Perthes-Calvé disease. The examination findings were useful not only for analyzing articular cartilages, limbus and chondro-articular surfaces in abduction and adduction but also for evaluating anteversion of bony and cartilaginous acetabula using an axial projection. The scanner provides comparable data with respect to the latter feature, but access is still more difficult.
