[Hip surgery in early childhood].

Congenital dysplasia of the hip after conservative treatment does not always lead to satisfactory results. Remanent hip dislocation causes severe problems for the gait and static of the vertebral column. Here surgical treatment in early childhood (open reduction, intertrochanteric osteotomy and roof plasty, may produce an essential improvement, even if for a long term arthritis may be expected. But nowadays we have satisfactory techniques of arthroplasties with wear resistant ceramic selflocking prostheses for these cases. Besides on the CDH valuable surgical methods are available also in other hip diseases in early childhood (myelodysplasia, Perthes, cerebral palsy). Indication and surgery need special experience.
