  • Developmental Dysplasia of the Hip (DDH) is a pathological condition commonly occurring during the growth phase of infants. It acts as one of the factors that can disrupt an infant's growth and trigger potential complications. Therefore, it is critically important to detect and treat this condition early. The traditional diagnostic methods for DDH involve palpation techniques and diagnosis methods based on the detection of keypoints in the hip joint using X-ray or ultrasound imaging. However, there exist limitations in objectivity and productivity during keypoint detection in the hip joint. This study proposes a deep learning model-based keypoint detection method using X-ray and ultrasound imaging and analyzes the performance of keypoint detection using various deep learning models. Additionally, the study introduces and evaluates various data augmentation techniques to compensate the lack of medical data. This research demonstrated the highest keypoint detection performance when applying the residual network 152 (ResNet152) model with simple & complex augmentation techniques, with average Object Keypoint Similarity (OKS) of approximately 95.33 % and 81.21 % in X-ray and ultrasound images, respectively. These results demonstrate that the application of deep learning models to ultrasound and X-ray images to detect the keypoints in the hip joint could enhance the objectivity and productivity in DDH diagnosis.

  • The purpose of this study was to analyze influential factors for blood transfusion for patients undergoing total knee arthroplasty and total hip arthroplasty, which are chronic degenerative arthritis, using the 2017 sample data of Health Insurance Review & Assessment Service, to research the impact of blood transfusion on the usage of medical services among arthroplasty patients, and ultimately to provide some information on how to offer quality medical services. The findings of the study were as follows: First, whether there were any significant differences in the use or nonuse of transfusion during total knee arthroplasty according to hospital characteristics and patient characteristics was compared. As for significant variables, the type of health care institution, the level of sickbed, gender and anemia were found to have been statistically significantly related. Second. whether there were any significant differences in the use or nonuse of transfusion during total hip arthroplasty according to hospital characteristics and patient characteristics was compared. As for significant variables, the type of health care institution and the level of sickbed were found to have been statistically significantly related. Third, whether there were any significant differences in the presence or absence of diabetes among the total knee arthroplasty patients according to hospital characteristics and patient characteristics was compared. As for significant variables, the type of health care institution, the number of sickbed and anemia were found to have been statistically significantly related. In the case of the total hip arthroplasty patients, there were no variables that were significantly related.
