developmental dysplasia of the hip (ddh) is the most frequent developmental disorder of the locomotor system. it is detected among 0.1–5.2% of newborns (1, 2). this might be the reason, that there is a high interest to detect ddh cases as early as possible. undetected or late cases lead to catastrophes for the patient and family. limping, leg length discrepancy, pain, frequent operations and so...

OBJECTIVE To investigate the coexistence rate and related factors of developmental dysplasia of the hip (DDH) and congenital muscular torticollis (CMT), and to determine whether ultrasonography (US) gives good value for screening of DDH in CMT. METHOD We prospectively examined 121 infants (73 males and 48 females) diagnosed with CMT to determine the incidence of DDH by US. We also assessed th...

BACKGROUND While cam resection is essential to achieve a good clinical result with respect to femoroacetabular impingement (FAI), it is unclear whether it should also be performed in cases of borderline developmental dysplasia of the hip (DDH) with a cam deformity. The aim of this study was to evaluate improvements in range of motion (ROM) in cases of cam-type FAI and borderline DDH after virtu...

Previous reports demonstrated 8-60% patients treated for developmental dislocation of hip (DDH) in infancy have residual acetabular dysplasia (AD) at skeletal maturity. AD patients reportedly exhibit abnormal morphology of the pelvis, high rates of comorbid spinal congenital anomalies and high bone mineral density. These physical findings suggest that AD patients have genetic background. We exa...

PURPOSE An association between congenital muscular torticollis (CMT) and developmental dysplasia of the hip (DDH) has been established in the literature; however, whether the screening of patients with CMT for DDH requires hip imaging remains controversial. The purpose of this study is to determine (1) the coexistence rate of DDH requiring treatment in individuals with CMT and (2) if physical e...

BACKGROUND The prevalence of developmental dysplasia of the hip (DDH) is unknown in China. We aimed to determine the prevalence of DDH in Chinese adults. METHODS In this study, we performed a cross-sectional survey of a nationally representative sample of Chinese adults. All participants underwent questionnaire investigation, physical examination, and X-ray examination. Factors associated wit...

By using mRNA differential display to examine specimens of non-small cell lung cancer (NSCLC), we have identified overexpression of dihydrodiol dehydrogenase (DDH) that was not detected in the corresponding normal lung tissue. Normally DDH is associated with catalysis of polycyclic aromatic hydrocarbons (PAHs) in the liver; in NSCLC cells, DDH expression would implicate an association with dise...

BACKGROUND The tachykininergic neurotransmitters have been proved to be involved in the inflammatory progress and chronic pain in series of disease. The present study was undertaken to evaluate the levels of substance P (SP) and its receptors NK-1 receptor (NK-1R) in both serum and synovial tissues of hip joint from patients with different stages of DDH, and to detect the possible correlation o...

Background: Developmental dysplasia of the hip (DDH) refers to a spectrum of disease, including hips that are unstable, subluxated, dislocated, and/or has dysplastic acetabula. Feet deformities such as clubfoot were mentioned in the literature as associated congenital anomalies in DDH patient with variable results. Multiple studies reported the correlation between DDH and congenital muscular to...

The etiology of developmental dysplasia of the hip (DDH) is unknown. There are many insights, however, from epidemiologic/demographic information. A systematic medical literature review regarding DDH was performed. There is a predominance of left-sided (64.0%) and unilateral disease (63.4%). The incidence per 1000 live births ranges from 0.06 in Africans in Africa to 76.1 in Native Americans. T...
