A comparative study on the effectiveness of two different devices in the management of developmental dysplasia of the hip in infants

AIM:The aim of this paper was to compare the results of treatment of developmental dysplasia of the hip (DDH) with two different devices. METHODS:In 118 DDH, authors employed, in a blinded randomized study, Teuffel-Mignon (TF) and Coxa-Flex (CF) devices. In this study checked 51 hips type IIC; 43 type IID; 15 type IIIA; 9 type IIIB, by Graf classification. RESULTS:Hips Graf's type C were recovered in median 60.09 days, with TM in 50, with CF in 63,45; hips type D in 100 days, with TM in 58,50, with CF in 89.00; hips type IIIA in 103.60 days, with TM in 122, with CF in 94.50; hips type IIIB in 108.66 days, with TM in 121, with CF in 102.50. CONCLUSION:The linear multiple regression model shows a statistically significant associations between outcome and pathological type (P value<0.001), age at diagnosis (P<0.001) and device (P
