    Description / Table of Contents: Résumé La crête iliaque a été pédiculée sur ses vaisseaux épiphysaires et transplantée sur le toit du cotyle en position intra-articulaire, en remplacement de la portion latérale de l'acétabulum qui a été réséquée chez 30 chiots âgés de 3 mois. Les meilleurs résultats sur la congruence articulaire, le maintien de la tête fémorale et l'aspect de la surface cartilagineuse aprés 9 à 18 mois, ont été obtenus dans les cas de greffons pédiculés verticalement insérés. En effet, ceux-ci sont le siège d'une croissance propre, évitant à la butée de remonter avec la croissance, et leur surface articulaire présente, en rapport avec la bonne vascularisation du cartilage hyalin sous-jacent, un aspect de cartilage normal. A la lumière de cette expérimentation, les auteurs proposent une nouvelle technique de traitement de certains états dysplasiques de la hanche chez l'enfant.
    Notes: Summary Pedicled iliac crest epiphysis transplantation was performed after resection of the outer portion of the acetabulum in 30 puppies 3 months old. The best joint congruency was obtained when using a vertical pedicled graft, the surface of which developed into normal articular cartilage through metaplasia, and presented normal cartilage growth by means of conservation of the epiphyseal vessels. The results of this experiment enable the authors to propose a new surgical technique in the treatment of certain difficult dysplastic conditions in the hip.

    Notes: Abstract  Objective. To evaluate the association of abnormal signal intensity within the sinus tarsi with abnormalities of the posterior tibial tendon (PTT) on MR imaging. Design and patients. Sinus tarsi abnormalities were identified on 30 ankle MR examinations in 29 patients. The PTT and anterior talofibular ligament were retrospectively analyzed for abnormalities in these same patients. Results and conclusions. Tears of the anterior talofibular ligament were found in 13 of 30 (43%) ankles. PTT abnormalities (complete tear, partial tear or dislocation) were seen in 14 of 30 (47%) studies, and were distributed relatively equally between those patients with and without lateral ligament tears. Our results provide evidence of an association between abnormalities of the PTT and the sinus tarsi. The finding of abnormal signal intensity within the sinus tarsi on MR imaging should alert the radiologist to potential abnormalities of the PTT.

    Notes: Abstract  Hip dysplasia is a not uncommon feature in adults and can vary from subtle acetabular dysplasia to complex sequelae of developmental dysplasia of the hip. This review article describes the most useful radiographic measurements used to evaluate the adult hip. The frontal projection of the pelvis permits measurement of the center-edge angle (CE angle) and ”horizontal toit externe” angle (HTE angle), both of which assess the superior coverage of the acetabulum. The femoral neck-shaft angle (NSA) is also measured on this view. The false profile radiograph of the pelvis is described. It allows measurement of the vertical-center-anterior angle (VCA angle), which determines the anterior acetabular coverage and detects early degenerative hip joint disease. When surgery is contemplated, computed tomography (CT) is useful to better determine the anterior acetabular coverage by use of the anterior acetabular sector angle (AASA), and the posterior acetabular coverage by use of the posterior acetabular sector angle (PASA). CT also permits measurement of femoral anteversion. These measurements are particularly useful in the evaluation of acetabular dysplasia and for the preoperative assessment of the dysplastic hip.
