![]() Dynamic splinting, represented by the Pavlik harness, is the preferred therapeutic option for children under six months with reducible DDH static bracing (e.g., the rhino brace) is for children over 6–9 months with DDH needing continued abduction positioning ( 6). Anteroposterior pelvic radiography is the first-line screening examination for evaluating DDH in children over 4–6 months ( 4). Early diagnosis and timely treatment of DDH are beneficial to promote normal hip development ( 3– 5). ![]() ![]() Its initial success lays the groundwork for developing a full-intelligent comprehensive diagnostic system of DDH.ĭevelopmental dysplasia of the hip (DDH) is a common skeletal deformity in children and the prominent cause of hip osteoarthritis and lower limb disability ( 1, 2). As for the lateral center-edge angle, the 95% limits were −3.68°–5.28° (junior orthopedist) and −2.94°–4.59° (intermediate orthopedist).Ĭonclusions: The software can provide expert-like analysis of pelvic radiographs and obtain the radiographic diagnosis of pediatric DDH with great consistency and efficiency. Compared with the expert panel, the Bland-Altman 95% limits of agreement for the acetabular index, as determined by the software, were −2.09°–2.91° (junior orthopedist) and −1.98°–2.72° (intermediate orthopedist). Results: In 543 cases (1,086 hips), the area under the curve, accuracy, sensitivity, and specificity of the software for diagnosing DDH were 0.988–0.994, 99.08%–99.72%, 98.07%–100.00%, and 99.59%, respectively. The diagnostic accuracy was evaluated using the receiver operator characteristic (ROC) curves and confusion matrix, and the consistency of parametric measurements was assessed using Bland-Altman plots. Two independent clinicians measured four diagnostic indices to compare the diagnoses made by the software and conventional manual method. Methods: In total, 543 anteroposterior pelvic radiographs were retrospectively collected from January 2017 to December 2021. This study aims to develop a diagnostic strategy-based software for pediatric DDH and validate its clinical feasibility. However, clinical thought-based analysis of hip parameters may be a more effective way to achieve expert-like diagnoses of DDH. 3Guangzhou Institute, Xidian University, Xi’an, Chinaīackground: The common methods of radiographic diagnosis of developmental dysplasia of the hip (DDH) include measuring hip parameters and quantifying the degree of hip dislocation.2School of Telecommunications Engineering, Xidian University, Xi’an, China.1Department of Orthopedics, Xijing Hospital, Air Force Military Medical University, Xi’an, China.Jia Sha 1,† Luyu Huang 1,† Yaopeng Chen 2,3 Zongzhi Fan 1 Jincong Lin 1 Qinghai Yang 2 Yi Li 2* Yabo Yan 1*
