A comparative study on the effectiveness of the two different devices in management of DDH in newborn and infants

118 developmental dysplasia of the hip (DDH) was detected by ultrasound (US) and classified following Graf’s criteria. A blinded randomized study on these cases was effected using Tueffuel-Mignon (59) and Coxa-Flex (59) devices, to evaluate effectiveness of both harnesses in DDH management. Study checked 51 type IIC; 43 IID; 15 IIIA; 9 IIIB. Type C recovered in 60,09 days, D in 100, IIIA in 103,60, IIIB in 108,66 days. Statistical model shows associations between outcome and pathological type (P<0.001), age at diagnosis (P<0.001) and device (P<0.02). Model shows that on average for each day of delay in diagnosis needed more than half a day for the patient to recover. Model confirmed that patients with serious pathologies need more time to recover. The treatment of DDH is based on the device, on the correct diagnosis with Graf’s method and on the early treatment, when the hip is more mouldable. Our opinion is that one device instead of another isn’t what’s important. What’s fundamental is the choice of the device based on long experience.
