The term "developmental dysplasia or dislocation of the hip" (DDH) refers to the complete spectrum of abnormalities involving the growing hip, with varied expression from dysplasia to subluxation to dislocation of the hip joint. Unlike the term "congenital dysplasia or dislocation of the hip," DDH is not restricted to congenital problems but also includes developmental problems of the hip. It i...

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 cross-s...

The less frequent variety of hip dislocation occurs before birth and may be associated with neuromuscular disorders such as arthrogryposis or myelomeningocele. The more common variety occurs at or shortly after birth. Therefore, in the common variety the acetabulum is well formed with secondary changes developing rapidly if the hip remains dislocated (13). Trueta (17) states that the latter oug...

not be. It is generally accepted by medical professionals that the manifestation of multigenetic disease during the lifetime of a gene carrier depends on certain environmental factors. This hip disorder can develop and even be exacerbated when certain environmental factors are present, but can also recede without further intervention following elimination of those same factors at an early devel...

In 1961 Andr#{233}nand Borglin suggested that congenital dislocation of the hip could be the consequence ofabnormal oestrogen metabolism in the perinatal period. They studied oestrogen excretion in eleven newborn infants with dislocated hips and twenty-six control infants during the first three days of life. They found elevated levels of oestrone and oestradiol in the patients with dislocation....

In a 10-year retrospective study of 25 921 consecutive deliveries in a neonatal unit in Newcastle upon Tyne 271 cases of congenital dislocation of the hips were identified. Of these, the outcome was unsatisfactory in 12: four diagnoses were missed at birth and eight children required further surgical treatment. Radiological abnormalities were detected in a further five children at long-term fol...

be congratulated on his admirable account of the operation of Lorenz in his book 'Congenital Dislocation of the Hip.' The operation is an extremely technical one, and the ordinary practising surgeon cannot hope to be successful except in a few cases, unless he has mastered all the details of the operation and seen it performed by an expert. There can be no doubt that the disease is not sufficie...

In a previous paper (von Rosen 1964) on the diagnosis and treatment of congenital dlslocation of the hip joint in the newborn our experience up to 1964 was summarised as follows. I ) Congenital dislocation of the hip can be diagnosed immediately after birth and the diagnosis can be confirmed radiologically by a special technique. 2) If the affected joint is reduced during the first three or fou...

This paper reports an investigation of the incidence of persistent generalised joint laxity in patients with congenital dislocation of the hip and in normal school children. Capsular laxity has attracted much attention in studies of the etiology of congenital dislocation of the hip joint. At first it was thought to be an isolated result of mechanical stretching. but it is now usually considered...
