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....

BACKGROUND The gluteus medius muscle is essential for gait and hip stability. Changes that occur in the gluteus medius muscles in patients with developmental dysplasia of the hip (DDH) are not well understood. A better understanding of DDH related changes will have positive repercussions toward hip soft tissue reconstruction. METHODS 19 adult patients with unilateral DDH scheduled for total h...

Developmental dysplasia of the hip (DDH) has been associated with other congenital postural deformities and associated with asymmetric features in the body. The aim of this study was to examine the associations between developmental DDH and malocclusions in preschool and school children. The subjects were 60 children (40 girls and 20 boys) born during 1997-2001 in Northern Ostrobothnia Hospital...

purpose: developmental dysplasia of the hip (ddh) increases the risk of secondary degenerative changes and subsequent total hip arthroplasty. the postoperative quality of life in patients with ddh who have been born and grown with this disability and adapted to it during the life, is one of the most challenging issues. this study aimed to compare the quality of life of patients with ddh before ...

BACKGROUND Developmental dysplasia of hip (DDH) is one of the congenital anomalies in newborns that if not diagnosed and treated on time can lead to a severe disability. Although clinical examination is a very useful way for screening, but in some patients, a confirmatory diagnostic method such as ultrasonography is needed. The aim of the present study is to compare the sensitivity and specific...

PURPOSE One goal of neonatal screening for developmental dysplasia of the hip (DDH) is the prevention of late surgery. However, the majority of patients with acetabular dysplasia at skeletal maturity are not diagnosed with DDH during infancy. Selective ultrasound screening may identify patients with neonatal hip instability, but may be ineffective for the prevention of dysplasia presenting in a...

The Decision Diie-Hellman assumption (ddh) is a gold mine. It enables one to construct eecient cryptographic systems with strong security properties. In this paper we survey the recent applications of DDH as well as known results regarding its security. We describe some open problems in this area.

Abstract Introduction Controversy exists surrounding the efficacy of UK screening programme for developmental dysplasia hip (DDH). Method Clinical records were reviewed in children who treated surgically DDH. Demographic data, age and mode presentation, surgical treatments analysed, as well outcomes, re-operation rate AVN incidence. Late diagnosis was defined greater than 4 months. Results 106 ...

PURPOSE Early detection and intervention for developmental dysplasia of the hip (DDH) is important for normal hip development. Previous studies have shown disparities in access to paediatric specialty care among different racial and socioeconomic backgrounds. This study aims to identify whether these factors are related to timely referral for infants with DDH. METHODS A retrospective cohort s...
