Few previous studies noticed the three bony structures that formed the acetabulum in developmental dysplasia of the hip (DDH). This study aimed at investigating the spatial changes of the peri-acetabular pelvis in developmental dysplasia of the hip through radiological evaluation of the patients and experimental observations in rat models. 115 unilateral DDH patients were studied through 3D-CT....

OBJECTIVE Development of the hip joint is complete by 11 weeks of gestation. As triiodothyronine and thyroxine are important regulators of early bone and muscle development, we hypothesized that excessive thyroid hormone in the early fetal period was a congenital risk factor of developmental dysplasia of the hip (DDH). Consequently, it was proposed that elevations of maternal thyroxine in the f...

Abstract Aim Early detection of developmental dysplasia the hip (DDH) is associated with improved outcomes conservative treatment. Therefore, we aimed to evaluate use a ‘clicky’ as an indication for secondary assessment per British Society Children's Orthopaedic Surgery (BSCOS) consensus statement. Method Prospective cohort study all patients born within catchment area single tertiary centre (n...

congenital hip dysplasia congenital hip dislocation developmental dysplasia of the hip ultrasonography, methods. The purpose of this study is to establish the diagnostic value of combine using static (Graf) and dynamic (Harcke) ultrasonography methods. Both static and dynamic methods were used only in Graf’s Type 1 and Graf’s Type 2a patients. Groups were classified as normal findings (Group A)...

Between 1985 and 1998, 12,331 patients were included in the general neonatal ultrasound hip screening programme for developmental dysplasia of the hip (DDH). Patients who needed treatment (604) were compared with a second group of 73 unscreened children treated conservatively and surgically for DDH. The incidence of Graf sonographic hip types IIc to IV varied throughout the observation period. ...

Purpose: Developmental dysplasia of the hip (DDH) comprises a spectrum abnormalities from instability to frank dislocation, Hip ultrasonography prior femoral head ossification, is recognized as an early diagnostic tool for DDH. It safe and non-invasive procedure, keeping those babies less than 6 months age away radiation hazard. Subjects Methods: From august 2021 until 2022, we investigated 534...

PURPOSE To review records of children referred to our hospital for developmental dysplasia of the hip (DDH) and evaluate the effectiveness of hip screening in Hong Kong. METHODS Records of children suspected of DDH and referred to our hospital between 1 January 2005 and 31 March 2010 were reviewed. The diagnosis was based on static and dynamic ultrasonography of the hips and/or radiographic f...

Developmental dysplasia of the hip (DDH) denotes a wide spectrum of pathologic conditions, ranging from subtle acetabular dysplasia to irreducible hip dislocation. When DDH is recognized in the first 6 months of life, treatment with a Pavlik harness frequently results in an excellent outcome. In children older than 6 months, achieving a concentrically reduced hip while minimizing complications ...

background: the prevalence of neglected developmental dysplasia of the hip (ddh) has been decreasing. nowadays, the disease is rarely seen in walking age children. the purpose of this study is to assess the results of simultaneous osteotomy of femur and pelvic bones in such children. method: we performed a retrospective study on 30 children aged 3.8±0.9 (range: 1.5-7) years old, with ddh who un...

The natural history of an untreated case of a Developmental Dysplasia (Dislocation) of the Hip (DDH) associated with multiple congenital abnormalities is reported in a 55-years-old man. The patient’s complaints and the varieties of the typical manifestations emerged in other parts of the body throughout the life are reviewed and discussed as comorbidities of a dysplastic condition. Two-stage bi...
