[Arthrography in congenital hip dislocation].

The paper is concerned with the results of contrast arthrography in 73 children with hip joint dysplasia, among which true dislocations prevailed (70 patients). In addition to bone alterations, arthrography revealed various soft tissue changes like hypertrophy and deformity of limbus, soft tissue interposition, separation of the articular sac with the presence of an isthmus, disintegration of articular cartilages. These findings are used to define indications for surgical intervention as well as for planning the area of operation.

[The effect of early surgical reposition of congenital hip dislocation and functional postoperative treatment on the development of the acetabulum].

Authors performed early operative reduction from anterior exposure after unsuccessful conservative treatment on 30 hips of 29 patients in 1981 through 1983. The age of the patients was 6-18 months at the time of the operation. After the excision of the obstacle of the reduction with preservation of the limbus the capsule was closed tight so that it could prevent redislocation. This way it became possible to make functional after treatment without plaster fixation and using Pavlik's harness and abduction splint. It was found that the postoperative development of the acetabulum was accelerated and the development of the acetabular roof reached in average during one year the healthy one and the articular movements were free. The development of the joint was the quicker the younger the age was in which the operation was performed.

[Complete surgical correction of congenital hip dislocation (one-stage surgery)].

A 3-10 years follow-up and the evaluation of the 55 cases operated 1980 through 1988 on the Orthopaedic University Hospital in Pécs is presented. The age of the patients at operation was 4.5-10 years, in average 4 years. The operation consisted of four components: operative reduction, varus derotation femoral osteotomy, acetabular plasty and transposition of the iliopsoas muscle. In 53 cases excellent or good Roentgen anatomical and functional results were found. In one case after the operation complete femoral head necrosis has developed, in two cases a transient ischaemic state was observed that healed however without functional deficiency.

[Congenital hip dislocation and the seasons].

This report deals with the data gathered for a year concerning the incidence of luxation coxae congenita at the Hospital de Gineco-Obstetricia (Gynecology-Obstetrics Hospital) of the Unidad Médica Oblatos (Oblatos Medical Unit) of the Instituto Mexicano del Seguro Social (Mexican Institute of Social Security) in the city of Guadalajara, Jalisco, México. The results show an inverse correlation between the temperature and the number of cases, both statistically significant, demonstrating seasonality for luxation coxae congenita.

[Incidence of congenital hip dislocation in 40,243 live births (I)].

During the period between 1981 to 1985, 40,243 children have been born. Among these children, 1,747 suffered from dysplasia, subluxation or dislocation of the hip. In this paper the following parameters are examined: frequency, sex, the hip affected and the order of birth. Dislocation of the hip is more frequent in females with a ratio of 5.3 to 1. The hip more frequently affected is the left. Fifty percent of the children affected are first-born. In this study we want to emphasize the importance of a thorough explanation of the newborn, due to the frequency of the affection and especially its greater frequency in female and its predominance in the left hip.

[Incidence of congenital hip dislocation in 40,243 live births (II)].

We study 1,747 children who presented luxating hip disease evaluating the following parameters: a) Frequency of breach presentation. b) Weight at birth. c) Inheritance. It was observed that out of 1,747 children affected, 159 were by breach presentation, representing 9.10%. With regard to weight, it seems that under-weight babies are more affected than those of average weight. Lastly, we observed greater incidence in patients with a family history of hip dysplasia.

[Early quantitative detection of vascularity of the reduced femoral head of congenital hip dislocation by scintigraphy].

Vascularity of the femoral head of CDH was detected by 99mTc-MDP scintigraphy before and after reduction. The results showed that a decrease of second time-activity, intersection of minute time-activity and remarkable decrease of relative ratio and corrected relative ratio on the part of femoral head which closed to the acetabulum is the diagnosis criterion for the obstruction of blood supply of the reduced femoral head. We confirmed that the mechanical pressure was the factor which caused the obstruction of blood supply of the reduced femoral head.

[The value of echographic studies in congenital hip dislocation].

Since the studies of R. Graf has echography of the hip replaced the standard X-Rays of the pelvis in the early diagnosis of CDH after birth. The authors report their experience with this technique in 400 newborn children. The technical aspects and results are described. The study is original because the pediatric orthopaedic surgeon does simultaneously the clinical examination under echographic control.

[Early diagnosis of congenital hip dislocation in neonates].

On the basis of the analysis of the examination of hip joints in 1000 newborns the author supports his former statement that of almost the same frequency as the acknowledged symptomatology of unstable hip joint (in 6.5 per cent) is the pathological symptomatic group of increased tension of tendons of the origin of adductors (in 4.7 per cent), sometimes also with reduced abduction, less palpable head of the hip joint and the symptoms presented by him can improve the quality of screen position case of breech presentation. This was found in 5.2 per cent of deliveries. The combination of both symptomatic groups occurs in 1.4 per cent. Out of individual symptoms in the breech presentation of highest frequency--according to the author--is the increased tension of the origin of adductors (in 94.2 per cent), be it isolated form of incidence (in 25 per cent) or in combination with other symptoms. In the examination technique he includes also the symptom of the hyperextensibility of the knee and relates its frequency (82.7 per cent) with the breech presentation and with the increased joint laxicity conditioned hormonally. After the analysis of mechanical effects in the foetal stage of pregnancy he attempts to correlate clinical neonatal symptomatology with the pathological anatomical classification after Ogden. He arrives at the conclusion that only combined identification of symptoms of both the instability of the hip joint and the symptoms presented by him can improve the quality of screening and thus reduce the incidence of unidentified defect of the hip joint in 3rd month of age of the child. Further progress can be made only after the introduction of a purposeful sonographic screening of the newborn and infant hip joints. The author, however, considers for irreplaceable the method of a careful clinical examination of newborns.
