Abstract
in English, French

This study examined the outcomes of ultrasound-monitored Pavlik harness treatment in 25 infants (2 boys and 23 girls) representing a total of 31 cases of developmental dysplasia of the hip of Graf type IIc or more severe. For all infants, Pavlik harness treatment started after ultrasonographic diagnosis in our clinic. If there was no improvement by the third week of follow-up, the harness treatment was discontinued. Of the 25 patients (31 hips), 16 patients (18 hips) were successfully treated with the Pavlik harness. The effects of age at start of treatment, gender, side of pathology, first clinical evaluation findings, bilaterality, and Graf type on Pavlik harness treatment success were analysed. We found that the outcome of treatment with the Pavlik harness was related to Graf type, age at start of treatment, and bilaterality.

Etude du traitement par harnais de Pavlik, avec contrôle par ultra-sons, de 31 dysplasies de hanche de type IIc ou plus selon Graf, chez 25 enfants (2 garçons et 23 filles). Dans tous les cas le traitement a débuté après un diagnostic ultrasonographique. En cas d’absence d’amélioration à la troisième semaine le traitement était arrêté. Sur les 25 patients, 16 (18 hanches) avaient un succés. Le rôle de l’âge au traitement, du sexe, du côté, de la première évaluation clinique, de la bilatéralité et du type selon Graf étaient étudiés. Nous avons constaté que l’efficacité du traitement par harnais de Pavlik dépend du type selon Graf, de l’âge au début du traitement et de la bilatéralité.
