✦ Synopsis


Experimental traumatic lesions of the iliac and pubic parts of the triradiate cartilage of the acetabulum in young Wistar rats, were created to study the effect on the development of the hip joint. Radiological, functional and morphometric results were evaluated at twelve weeks of evolution, a time when the epiphysis was mature in a control series. Interference with the pubic growth plate caused acetabular dysplasia and dislocation of the hip. Both lesions caused deformities of the acetabulum and the femoral head. It is concluded that varied traumatic lesions of the triradiate cartilage may be of prognostic significance.

R/~sum~. Les auteurs ont rbalisk une lbsion traumatique de la zone de croissance iliaque ou pubienne du cartilage en Y chez des rats Wistar afin d'ktudier le r61e de cette structure dans le dkveloppement des anomalies de la hanche. Les rbsultats radiologiques, fonctionnels, morphologiques et morphombtriques ont btO bvalu~s h la douzikme semaine d'bvolution. Dans les Ibsions du cartilage de croissance pubien, les constatations les plus remarquables ont btk les dysplasies acktabulaires et les luxations.

Des modifications de forme de l'acetabulum et de la t~te fbmorale ont btk notkes dans les deux groupes. On en conclut que le diagnostic de traumatisme du cartilage en Y peut avoir un grand intbr~t dans le pronostic des lksions de la hanche.

## Abstract In an attempt to produce necrosis of the femoral head, the medial femoral circumflex vessels were disrupted in 13 normal piglet hips through a medial approach. Femoral heads were recovered 3–6 months (average 4.2 months) postoperatively. None of these hips showed gross, radiographic, or
