Deep Dive in DDH is a three-part limited series where experts in the field of DDH have been invited to discuss the controversies in the management of hip dysplasia. Episode 1 was published in August and discussed management of DDH in infants under 6 months of age. Episode 2 was published in January and discussed the controversies in the management of developmental hip dislocations in the operating room. For the final episode we are joined by Drs. Rachel Goldstein from Children’s Hospital of Los Angeles and Steve Frick from Atrium Health in Charlotte. This episode focuses on evaluation and management of residual dysplasia including nonoperative management with bracing, surveillance, and if/when to operate.
