The incidence of congenital dislocation of the hip (CDH) in Birmingham was measured in the period 1942-52 and again in 1950-54; it is measured now in 1974-83. Despite the introduction of neonatal screening for CDH in November 1966, between the times of the earlier and the present measurements there was no indication that CDH requiring prolonged treatment had declined. The performance of the pro...

OBJECTIVE To determine reliability of the measurement of hip movements (flexion, internal rotation, and external rotation) between medical practitioners. METHODS Six clinicians carried out measurements of hip movements on each of six patients with osteoarthritis of one hip, using a specifically designed plurimeter. RESULTS There was no evidence of any systematic difference between medical p...

A lightweight, washable, and easily adjusted splint for the congenitally dislocated hip, designed to improve maternal compliance, is described. Observations are currently scientifically uncontrolled, though initial impressions are favourable.

For the last few years nearly all newborn infants born in Budapest, a city of two million inhabitants, have received an orthopaedic examination which includes a screening test for congenital dislocation of the hip (CDH). Suspected cases of CDH were kept under observation and received treatment if necessary. In this way a total of 3,000 treated cases born between 1962 and 1967 became available f...

To assess the effect of improved methods of femoral cementing on the loosening rates in young patients, we reviewed 50 'second-generation' cemented hip arthroplasties in 44 patients aged 50 years or less. The femoral stems were all collared and rectangular in cross-section with rounded corners. The cement was delivered by a gun into a medullary canal occluded distally with a cement plug. A clin...

The treatment of congenital dislocation of the hip from birth should give excellent results in almost every case under adequate supervision. Nevertheless difficulties still arise despite increasing awareness and more regular routine examination of the newborn. Accurate examination and treatment can be organised with less difficulty in large maternity units than in small units, peripheral hospit...

The reported prevalence of established dislocation the hip in an unscreened population varies from 0.7 to 1.6 / 1000 children in European and American white populations. In clinically screened populations neonatal hip instability is reported to occur in 3 to 30 / 1000 newborns while established congenital dislocation has a prevalence of 0.1- 4/1000 of which 1/1000 is judged to be in need for su...

We observed the upward displacement of femoral heads in skeletal remains two females unearthed from medieval cemetery monastery Santa Maria Valle, Cividale del Friuli (North-Eastern Italy). Examination bone vestiges suggests diagnosis hip dislocation as consequence developmental dysplasia hip. In addition, youngest subject first sacral vertebra appears lumbarized and shows unilateral defect rig...

One of the most common causes for revision surgery following total hip arthroplasty (THA) is dislocation.Dislocation is associated with a considerable amount of suffering and risks for the patient, and extra costs for the health care system.Compared with degenerative arthritis, the dislocation rate is doubled for avascular necrosis and multiplied by three times for congenital dislocation, four ...
