[Conservative and surgical treatment of hip dysplasia and dislocation].

Almost in any case of hip dislocation and dysplasia, diagnosed within the first 3 months of live conservative treatment is successful. Very instable hips have to be treated with plasters. Because of the danger of necrosis of the femoral epiphysis the Lorenz position of hip plasters is no more longer accepted. The only way to avoid this complication is to use the human position (110 Grad flexion, 60 Grad abduction) for hip spikas. Surgical methods are necessary in cases of late diagnosis, or of neglected conservative therapy.
