Congenital dislocation of the hip, with late diagnosis after 1 year of age: update and management.

When congenital dislocation of the hip (CDH) is diagnosed only after walking age, management is greatly complicated. In view of the increasing number of such cases treated by members of the French Society of Paediatric Orthopaedics (SOFOP) in recent years, a 3-part study was conducted within the Society to shed light on the reasons for late diagnosis, to give an update on treatment strategies currently implemented in France, and to report long-term outcomes.
