Open reduction by the Ludloff approach to congenital dislocation of the hip under the age of two.

The technique of Ludloff is particularly indicated in treating congenital dislocation of the hip, under the age of two. The procedure is relatively simple, provides direct access to the most important pathology, limited blood loss and a good cosmetic result. In the period between 1981 and 1984, 26 congenital dislocations of the hip were treated in our department, by the Ludloff technique. A re-evaluation of these cases was performed after a period of 4 years and 6 months. 23 hips were concentrically reduced; there were 2 redislocations, 1 deep infection and 2 cases of avascular necrosis, type I.
