Experience in the application of the Graf technique in Beijing

Abstract

Aim: The aim was to review several aspects of work using ultrasound in diagnosing developmental dysplasia of the hip and analyze the application status of the Graf technique in Beijing over 15 years. Methods: First, data on the promotion and development of the Graf technique in Beijing over the past 15 years were retrospectively analyzed. Second, data on hip ultrasound (US) screening and the effect of consecutive brace therapy were collected and analyzed. Infants were divided into subgroups according to Graf type, age at initiation of treatment, sex, and affected side. Results: The ultrasound detection rate of developmental dysplasia of the hip (DDH) was high at Beijing Jishuitan Hospital. The total detection rate of type IIa, IIb, IIc, D, III and IV (abbreviated as: types IIa and worse) was 4.58%, and that of type IIb, IIc, D, III and IV (abbreviated as: types IIb and worse) was 1.40%. Clinicians should pay attention to DDH, and early treatment is important; therefore, it is recommended that infants and young children undergo DDH ultrasound screening as soon as possible. Our research shows that when the α angle was more than 43°, the efficacy of brace therapy was 95.95%. Conclusions: It was confirmed that the Graf technique has greater practicality and accuracy. The Graf technique, as an important means for the early screening of DDH, has been widely recognized around the world, and it is recommended to be widely used in China to preserve future health in as many children as possible.
