The invention relates to an ultrasonic image processing method and system for infant developmental dysplasia of hip joints, and the method comprises the steps: obtaining an infant hip joint ultrasonic image to be diagnosed, and segmenting the ultrasonic image into independent image frames; performing target detection on the picture frame to obtain a hip joint bounding box, and preliminarily screening a standard image based on the hip joint bounding box; key point detection is carried out on the basis of the hip joint bounding box, and key point coordinates and confidence are obtained; screening the standard image again based on the key points and the confidence thereof; calculating a reference radius for the screened standard image, and further selecting an optimal standard image; and calculating an alpha angle and a beta angle based on the key point position in the optimal standard image. Compared with the prior art, the image meeting the Graf method standard can be quickly screened out from the original ultrasonic image, meanwhile, the target angle is automatically calculated through the standard images, doctors are assisted in evaluating the development state of the hip joint, and the time and workload of the doctors are remarkably saved.

Embodiments of the present disclosure provide a method for treating developmental dysplasia of the hip. The method includes administering a therapeutically effective amount of a pharmaceutical composition to a subject suffering from the developmental dysplasia of the hip. The pharmaceutical composition includes a substance capable of inhibiting expression of Midkine (MDK), and the substance capable of inhibiting the expression of MDK is Midkine inhibitor (IMDK).

The invention relates to the field of medical systems, in particular to an auxiliary diagnosis system for child developmental dysplasia of hip joints, which comprises an information input module used for inputting multi-aspect information of children; the analysis module comprises a trained convolutional neural network, the convolutional neural network is used for training hip joint ultrasonic images of children of 4-6 months old under multi-aspect information, the convolutional neural network is used for judging whether diagnosis features in the hip joint ultrasonic images meet diagnosis requirements or not, and the convolutional neural network is used for collecting input information of the information input module; and outputting the reference probability that the ultrasonic detection meets the diagnosis requirement. By the adoption of the technical scheme, the method is used for predicting the developmental hip joint dysplasia probability of 4-6-month-old children through multi-aspect information, medical workers are assisted to make examination mode decisions, and the frequency of invalid ultrasonic detection conducted by the medical workers is reduced.

The present invention discloses a biological acetabular partial reconstruction prosthesis for treating hip dysplasia, which comprises a specific base and an articular surface coating. The upper end of the specific base is pointed and small, while the lower end is thick and large. It includes an acetabular contact surface, a soft tissue contact surface and a femoral head joint engagement surface. The acetabular contact surface and the soft tissue contact surface enclose the side surface of the specific base, and the femoral head joint engagement surface constitutes the bottom surface of the specific base. The specific base is a three-dimensional porous network structure. The biological acetabular partial reconstruction prosthesis for treating hip dysplasia disclosed by the present invention enables patients to improve the biomechanical environment of the hip joint, delay the progression of hip arthritis, and avoid the disadvantages of large surgical trauma and poor morphological combination of the existing periacetabular osteotomy. At the same time, it can be applied to the early treatment of sequelae of hip dysplasia, delay or avoid joint replacement, and has a significant effect on the treatment of patients with mild hip dysplasia.
