Periacetabular osteotomy (PAO) is an effective treatment to correct developmental dysplasia of the hip (DDH). Traditionally, the goal of correction during PAO is based on parameters measured on 2-dimensional images. The aim of the study is to introduce an optimized workflow of PAO in DDH patients by means of personalized correction goal and accuracy of execution.

This study aims to develop and evaluate an artificial intelligence (AI)-based diagnostic system for the diagnosis of developmental dysplasia of the hip (DDH) in infant hip ultrasonography. The Graf algorithm was employed to develop an automated model for diagnosing DDH, resulting in a DDH-assisted AI model with an average Graf angle error rate of 0.21 compared to expert diagnostics. NASNetMobile achieved the highest Area Under the Curve (AUC) of 0.864 (95% CI, 0.850-0.878), closely followed by MobileNetV1, DenseNet121, EfficientNetV2B0, NASNetMobile, and ResNet50. UnestedUNet demonstrated the highest overall performance, achieving Dice coefficients of 0.794 and a runtime of 40.078 ms, demonstrating its strong segmentation accuracy with moderate computational demands. DeepLabV3Plus, a handheld ultrasound device integrated with a smartphone, demonstrated a robust and efficient segmentation performance. This study highlights the transformative potential of integrating AI into portable ultrasound devices, enabling accurate, efficient, and accessible diagnostic solutions.

The study objective was to evaluate the relationship between the first hip ultrasound (HUS) result and developmental dysplasia of the hip (DDH) diagnosis in preterm infants. Additionally, we report the types of treatment for preterm infants diagnosed with DDH.This is a retrospective chart review of infants born between January 1, 2009, and December 31, 2018, at <37 weeks of gestation who had HUS in the first year of life. Positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity for abnormal and normal HUS results were calculated.From 2,397 infants analyzed, 71 (3%) infants were diagnosed with DDH. The majority (

For children aged 18 months and above with developmental dysplasia of the hip (DDH), treatment typically involves open reduction and hip reconstruction surgery. However, there is limited literature evaluating the efficacy of closed reduction in this patient population. The purpose of this study was to investigate the clinical efficacy of closed reduction and spica cast immobilization treatment for children aged 18 months and above with DDH, as well as the incidence of avascular necrosis of the femoral head (ANFH) and their associated risk factors.

To evaluate the performance of high-resolution deep learning-based hip MR imaging (CSAI) compared to standard-resolution compressed sense (CS) sequences using hip arthroscopy as standard of reference.

Mucopolysaccharidosis type IV also known as Morquio syndrome is a rare autosomal recessive lysosomal storage disorder due to deficiency of either N-acetyl-galactosamine-6-sulfatase (type A) or deficiency of beta-galactosidase (type B) which results in damages of bones, cartilages, eye corneas, skin and connective tissue. The objective of this study was to explore the relationship between specific gene mutations (c.860C>T, c.421T>A, c.1196delA) and clinical manifestations in patients with mucopolysaccharidosis type IV (MPS IV. The study was conducted at Heevi Tertiary Hospital in Duhok, Iraqi Kurdistan, till the period of September 2024, it involved 10 patients with confirmed MPS IV. Data on demographics, family history, consanguinity, skeletal, intelligence, and genetic mutations were collected. Results showed that mean age at diagnosis of 7.94 years, with females predominating. Consanguinity and family history were common. Short stature, macrocephaly, fatigue, generalized pain, and various skeletal abnormalities such as dysostosis multiplex and others. Hip dysplasia was present in 50% of patients, while intelligence was normal in most. The most frequent genetic mutation was c.860C>T, followed by c.421T>A and c.1196delA. Biochemical and hematological parameters were within normal ranges, but growth retardation was evident. Geographic clustering of mutations was noted, with c.860C>T prevalent in Zakho and c.1196delA exclusive to Akre. In conclusion, the study highlights the severe phenotypic expression associated with these mutations and underscores the influence of consanguinity and regional genetic predispositions. These findings emphasize the need for targeted genetic counseling and population screening programs in high-risk areas.

Femoral neck fractures, pose significant risks of AVN and non-union. Recent studies suggest that adding capsulotomy to CRIF could reduce complications by alleviating intracapsular pressure and enhancing femoral head vascularity. This study aims to assess the efficacy of capsulotomy combined with CRIF in reducing the incidence of AVN and non-union in Garden III femoral neck fractures compared to CRIF alone.

Developmental dysplasia of the hip (DDH) exhibits abnormalities in hip anatomy, so changes in the acetabular and femoral angles hold clinical relevance. This study aimed to investigate the correlations between acetabular anteversion (AAV) and acetabular abduction (AAB), as well as between combined anteversion and combined abduction in patients with DDH, attempting to give evidence for synchronous torsion of the proximal femur and acetabulum. This study also aimed to propose a new method for predicting acetabular anteversion and combined anteversion angles, respectively, based on acetabular abduction and combined abduction angles on conventional pelvic radiographs.

Developmental dysplasia of the hip (DDH) is a complex static-dynamic condition resulting in chronic joint instability and osteoarthritis. Borderline acetabular dysplasia refers to slightly abnormal patterns in the acetabular shape and coverage that are not within the dysplastic range. However, they can predispose to mechanical dysfunction and hip instability. Diagnosis and treatment remain controversial topics in hip preservation, with little current comparative literature to guide accurate diagnosis and treatment decision-making. Historically, the diagnosis of borderline DDH relied on assessments of the acetabular anatomy on anteroposterior pelvic radiography, most commonly the lateral central-edge angle (LCEA), with normal values ranging from 20 to 25° or, in some more recent studies, 18 to 25°. Surgical treatment decision-making debates the use of isolated hip arthroscopy or periacetabular osteotomy, considering the difficulty in determining a fundamental mechanical diagnosis (instability versus femoroacetabular impingement) in subjects with borderline DDH. Therefore, for effective surgical decision-making, the evaluation of additional bone anatomy characteristics, instability, and patients' features is essential.

Hip dysplasia (HD) is a prevalent cause of non-traumatic hip pain, which may result in osteoarthritis. Radiological measurements of HD exhibit variability based on reader and imaging modality, why it is important to know the agreement between different measurement methods.
