Therefore, early detection and management is crucial to improve the outcome and minimise the risk of osteoarthritis in later life. Hip ultrasound is used to evaluate DDH based on Graf classification. Graf score is a widely used ultrasound grading score to evaluate DDH in infants. There is conflicting evidence regarding the management of the developmentally immature Graf type IIa hip. Some physicians adopt watchful waiting for natural maturation of hips while other early treatment. This article will provide an evidence-based review on the management modalities of the Graf type IIa hip.展开更多
