On 813 in-patients with congenital dislocation of the hip or it's residual disorders treated in our clinic during the last nineteen years (1952-1970), evolution of the treatments (conservative 440, operative 373 cases) were annually analysed.
Conservatively, the treated cases for early infants period have increased lately: Cases less than one year of age were 4% of total ones during the early three years (1952-1954) and 35% during the last three years (1968-1970). Up to now, so-called Lorenz methods have been used chiefly for inpatients, however, the number of cases has decreased and these are giving place to Pavlik's bandage methods for out-patients.
Surgically, though Colonna capsular arthroplasties were performed in 90% of 58 cases before 1965, nothing but 2 cases after 1966. While 93% of 73 open reductions of hips were actively applied after 1962 and 77% of 95 osteotomies against residual disturbances for the last seven years (1964-1970). Only shelf operations (167 hips) were used constantly through the reviewed periods.
