BACKGROUND Congenital dislocation of the knee (CDK) is a very rare condition that comprises a spectrum of deformities from subluxation to complete dislocation. The incidence of CDK is estimated at 1 per 100,000 live births, which is 1% of the incidence of developmental dysplasia of the hip (DDH). Moreover, 40-100% of patients with CDK have additional musculoskeletal anomalies, the most common b...

PURPOSE Developmental dysplasia of the hip (DDH) is a term used to cover a broad spectrum of anomalies ranging from mild dysplasia to high-riding dislocations. We report the management of DDH in children using the Dega osteotomy and their long-term follow-up. METHODS Fifty-eight hips from 48 children younger than 8 years treated using the Dega osteotomy between January 1988 and October 2000 w...

background : developmental dysplasia of the hip (ddh), formerly known as congenital dislocation of the hip (cdh) is a common congenital malformation which occurs worldwide with variable frequencies in respect to the race and geographic distribution.    objective: to determine the incidence of ddh, its predisposing factors and the diagnostic value of click for its detection.   methods : in a cro...

The biomechanical factors influencing reduction of dislocated hips by the Pavlik harness in patients of Developmental Dysplasia of the Hip (DDH) were studied using a three-dimensional dynamic computer model capable of simulating hip reductions in (1) subluxated and (2) fully dislocated hip joints. Eight hip adductor muscles were identified as key mediators in the prognosis of hip dysplasia and ...

BACKGROUND Developmental dysplasia of the hip (DDH) is an important factor leading to early adult osteoarthritis. Chondrocyte apoptosis has been proven to be an important factor causing osteoarthritis. AIMS The current study aims to explore whether a rabbit model of developmental dysplasia of the hip through cast immobilization in the legs results in chondrocyte apoptosis. STUDY DESIGN Anim...

Developmental dysplasia of the hip (DDH) is a complex disorder of the hip joint affecting 1-5‰ of newborns. While genetic influence on DDH has been long known, DDH has not been ascribed to any specific genetic event. The present study reported on variants contributing to DDH susceptibility in a family with four individuals affected across three generations. Whole-exome sequencing was performed ...

Hip joint instability can be secondary to congenital hip pathologies like developmental dysplasia (DDH) or acquired such as sequel of infective or neoplastic process. An unstable hip is usually associated with loss of bone from the proximal femur, proximal migration of the femur, lower-extremity length discrepancy, abnormal gait, and pain. In this case series of 37 patients coming to our instit...

Developmental disorder of the hip (DDH) is the most frequent disease of this joint. It is manifested by dysplasia, subluxation or luxation in childhood period and arthrosis in adults. Early degenerative changes of the hip occur at the location of disordered anatomy and biomechanics already in youth, while in the childhood age they are mostly asymptomatic (Ando & Gotoh, 1990). DDH mostly occurs ...
