Hip surveillance, research and interventions. Copyright Bill Reid, Pam Thomason and Kerr Graham, RCH Melbourne. Hip surveillance for children with CP improves the knowledge and research base. It can help us understand why hips dislocate and effects of intervention on the natural history of hip migration. Hip surveillance usually leads to interventions, which can be proactive or reactive and include both non-operative and operative approaches. Hip surveillance, research and outcome studies are inextricably linked. Each informs the other.
