Abstract:
Objective To evaluate the effect of abducens orthosis combined with walker on de-velopmental dysplasia of the hip ( DDH ). Methods A total of 126 patients (224 hips ) with DDH aged 6～36 months in Xiangya Hospital was randomly divided into 2 groups: an orthosis combined with walker group and an improved hip frog cast fixation group. Seventy patients (130 hips) were treated by the orthosis combined with walker and 56 patients (94 hips) were treated by the improved hip frog cast fixation. We compared the effect and complications of the 2 groups. Results The fine-ness rates of the orthosis combined with walker group and the improved hip frog cast fixation group were 89.2% and 90.4% , respectively, with no significant difference (P>0.05). The rate of femoral head osteonecrosis in the orthosis combined with walker group was significantly lower than that in the improved hip frog cast fixation group (1.5 % vs. 5.3 % , P<0.05) , but the re-dislocation rate in the former was significantly higher than that in the latter (6.9 % vs. 1.1% , P<0.05). Conclusion Both methods are effective for DDH. Orthosis combined with walker has a lower propor-tion of femoral head osteonecrosis, but a higher proportion of re-dislocation.
