[The effect of ultrasonography screening of hips in newborn infants on femur head necrosis and the rate of surgical interventions].

We compared two similarly sized groups of sonographically unstable or decentered hips with comparable initial findings, both treated by standardized conservative primary treatment. The results show that an early definite diagnosis improves the prognosis. If built on a secure initial diagnosis rationally grounded and efficient conservative therapy can be initiated and followed through on. Since the treatment is started extremely early, the hip can benefit from the considerably greater potential for spontaneous development present in the first three months of life. In this way we can shorten the treatment time considerably and also complete it at a younger age. Finally, early treatment also reduces the risk of the complication of necrosis of the femoral head and significantly decreases the rate of surgical procedures. Only a sufficiently well executed and comprehensively organized sonographic neonatal screening program can produce a definite very early diagnosis and with it almost 100% successful early treatment of all grades of disturbances of hip maturity. Sonographic screening of the newborn is a very important piece in the jigsaw of prophylaxis and primary prevention in our public health care program.
