Total hip arthroplasty in congenital dislocated hips.

Experience with six typical cases demonstrates that total arthroplasty for congenital dislocated hips may be associated with malalignment of the ipsilateral knee, leg-length inequality, pelvic obliquity and structural changes in the lumbosacral spine. The preoperative planning may include computerized tomography scan to obtain accurate information about the optimal placement of the socket and the size and shape of the prosthetic components. Loosening of the stem or socket rather than polyethylene wear is the expected cause of late failure. The design of the femoral component should fit the canal and the shape of the proximal femur. Biological causes for failure, such as granulomatous reaction to wear, particles, and infection, are known but were not encountered in the present series of cases. The surgical technique is designed to obtain complete coverage of the socket in the available bone. A supplementary bone graft provides additional bone stock and is especially important for revision operations. Orientation of the components, stability of the joint, the need for tenotomy of contracted structures, and the improvement of abduction and flexion muscle power are also important considerations. Elderly patients with degenerated, painfully dislocated hips that are refractory to conservative treatment, may be candidates for arthroplasty.

Salter's innominate osteotomy in the treatment of congenital hip dislocation: a long-term review.

We reviewed 39 patients with 52 congenitally dislocated hips, all managed by open reduction and Salter's innominate osteotomy. Mean follow-up period was 13 years (range, 8 to 25 years); 78.9% of the hips had a good or excellent clinical result, and 71.1% were good or excellent radiologically. The patients who underwent Salter's innominate osteotomy before the age of 4 had better clinical and radiological results (88.4 and 81.4%, respectively). The radiographs of the unilateral normal hips were compared to the surgically treated hips according to their acetabular index angles, center-edge angles of Wiberg, and femoral neck-shaft angles. No statistical differences were found between these two groups. The Bucholz-Ogden classification was used for the diagnosis and classification of avascular necrosis. The late radiographic signs of types 2, 3, and 4 avascular necrosis were seen in 34.6% of this series. The results show that Salter's innominate osteotomy provides good lateral coverage of the femoral head. The results are better if the operation is performed between the ages 18 months and 4 years.

Three-dimensional computerized selection of hip prostheses in patients with congenital dislocated hips.

This study assessed the effectiveness of the combined use of computed tomography (CT) and computer-aided design (CAD) in the preoperative evaluation and implant selection in 20 patients (20 hips) with congenital dislocation of the hip who were scheduled to undergo total hip arthroplasty. Computerized selection of the femoral implant with optimum fit and fill was made after a three-dimensional reconstruction of the femoral canal using CT data and CAD. Implantation of all sizes of 5 noncemented and 2 cemented femoral implants was simulated using CATIA software (IBM, Kingstone, NY). When patients underwent surgery, 18 of 20 preselected prostheses agreed by type and size with the prostheses implanted. The remaining 2 preselected implants agreed by type only. In patients with dislocated and dysplastic hips, combined use of CT and CAD allows effective preoperative planning by providing the surgeon with vital information about the proximal femoral canal geometry and the possible femoral implant with optimum fit and fill to be used.

[The influence of ultrasonography on the diagnosis and treatment of so-called congenital hip dislocation].

By means of a retrospective analysis of the hospital reports of 107 children with 131 dislocated hips we investigated the influence of ultrasound examination on the diagnosis and therapy of congenital dislocation of the hip. We could show, that although the ultrasound examination had increased since 1985 the number of dislocated hips receded only little. However the diagnosis was made earlier in children who had been examined by ultrasound. In these children operative reposition of the dislocated hip had to be performed less frequently compared to the unexamined children. Several case reports are given to demonstrate typical faults in ultrasound diagnostics and treatment of congenital hip dislocation. Our results support the call for a general ultrasound screening of the newborn hip.

Patient follow up screening evaluations. Examples with regard to congenital hip dislocation and congenital heart disease.

OBJECTIVE: To discuss the merits of the patient follow up study design for the evaluation of some specific mass screening programmes. DESIGN: Theoretical evaluation illustrated by two examples. SETTING: Department of Public Health Erasmus University Rotterdam. MAIN RESULTS: The gold standard for evaluation of favourable effects of screening is the randomised controlled trial (RCT). Application of an RCT, however, is often not feasible, in which cases observational studies will have to be relied on. The case-control study design is generally considered to be second best. In some situations, however, a patient follow up study design may be applicable and may have some major advantages. The use of the patient follow up design for screening evaluation will often be very problematic or even unacceptable, particularly as far as screening for cancer is concerned. The most important objections are resulting from lead time bias, length bias, selection bias and over-treatment bias. For the evaluation of screening for congenital heart disease and congenital hip dislocation in Dutch child health care, however, these objections may relatively simply be overcome. Lead time bias will be of little importance, as the ages of onset of these disorders are fixed, namely at birth, and their ultimate outcomes may be expected within relatively short time. Length bias may largely be avoided by correction for severity of the disorder, which can be adequately assessed by modern diagnostic procedures. Selection bias is generally hard to rule out, but in these cases it probably plays a minor part. Over-treatment can be avoided by the policy of "watchful waiting", which in these disorders can be applied with little risk for fatal outcomes. In principle bias might be avoided more successfully in a case-control screening evaluation than in a patient follow up study. However, the patient follow up study is for both screening programmes discussed here the more feasible design and can provide more supplementary information. The results of two example studies suggest that both screenings probably yield considerable benefits CONCLUSION: Under a number of specific conditions a patient follow up study is an efficient alternative to more customary designs for screening evaluation.

[Arthroplasty of the hip joint in children and adolescents with congenital hip dislocation].

The work is devoted to operative treatment of children with repeated dislocations and ankyloses of the hip joint after operative treatment of congenital dislocation of the hip. The dura mater, demineralized allocups and polymer self-resolving film were used as interlayers. Best results were obtained in arthroplasty with using demineralized allocups, polymer self-resolving film or their combinations.

Guided abduction traction in the treatment of congenital hip dislocation.

Guided abduction is a form of overhead traction conceptually similar to the Pavlik harness. It is used in older children or in children in which the Pavlik harness has failed. The results of 27 congenitally dislocated hips treated by guided abduction traction from December 1979 to June 1989 were reviewed. Ages ranged from 1 month to 28 months. Twenty (74%) of the 27 hips underwent a gentle, often spontaneous, closed reduction, followed by abduction casting and bracing. Two hips developed radiographic evidence of avascular necrosis; five hips developed temporary irregular ossification. Closed reduction was unobtainable in any child older than 24 months. Two children needed additional reconstructive procedures, one an innominate pelvic osteotomy and the other a valgus derotation osteotomy. Both had had open reductions. Recent reports stated that preliminary traction in the treatment of congenitally dislocated hips is of no value. We consider guided abduction traction a valuable treatment modality resulting in a reduced incidence of open reduction. When comparing our results with those of a Salt Lake City study performed without preliminary traction, our incidence of open reduction is lower (26 versus 49%). Our study supports the use of preliminary traction to decrease the need for open reduction in congenitally dislocated hips.

[Multicenter Belgian study of the results of total arthroplasty for persistent congenital hip dislocation].

The SO.B.C.O.T. proposed a multicenter study of the results of total hip replacement performed in Belgium for treatment of severe congenital dislocation. Eleven departments with about 30 surgeons contributed to this retrospective analysis, in which cases treated in different centers with various techniques are reviewed. Difficulties in data collection are discussed. Owing to the variety of data, the article is divided in 2 sections: an inquiry or descriptive analysis of congenital dislocation of the hip treated in Belgium between January 1972 and December 1987; the midterm results achieved by different techniques.

Growth and development of congenitally dislocated hips reduced in early infancy.

We determined the acetabular angles, center-edge angles, comprehensive quotients, and Shenton's lines from sequential roentgenograms of thirty-seven children with congenitally dislocated hips treated by closed non-manipulative reduction in early infancy. The values were compared with those obtained from roentgenograms of 164 normal children who ranged in age from three months to five years and of forty-three adolescents and adults. The hip recovering from congenital dislocation developed similarly to the normal hip but differed in that it showed a greater rate of decrease of the acetabular angle and an increase in the center-edge angle. Significant development after the age of five years still was manifested in the reduced hips.

Obturator dislocation as a complication of closed reduction of the congenitally dislocated hip: a report of two cases.

Two cases of inferior obturator dislocation complicating treatment of congenital hip dislocation with closed reduction are described. Abduction and hyperflexion appear to be predisposing factors in development of this complication. Application of skin traction before any attempt is made at reduction will lengthen contracted soft tissues and may convert the inferior dislocation to a more manageable position. Open reduction was necessary in both patients, and the results were considered good.

The treatment of congenital hip dislocation between the ages of 1 and 3.

A total of 81 patients (103 hips) with a diagnosis of congenital hip dislocation were reviewed, who had been treated between one and three years of age. All of the patients were initially treated with adhesive band traction prior to non-surgical reduction, which was performed under general anesthesia using gentle reduction maneuvers followed by immobilization in plaster. Non-surgical reduction was performed in 69 hips (67%), surgical in the remaining 34 (33%). A total of 91 associated surgical procedures were performed for the treatment of residual subluxation. Average follow-up was 12 years (minimum 5, maximum 19). The clinical results of the non-surgical reductions were excellent in 75% of the cases. Radiographically, 48% are hips which have a normal aspect, while 42% have a moderate degree of residual dysplasia or deformity of the femoral epiphysis and of the acetabulum. Hips that were initially classified as grade III dislocations show fair results. Hips treated non-surgically included 11 cases of avascular necrosis (16%); recovery was adequate. Hips treated surgically included 14 cases of avascular necrosis (30%), which was more accentuated in those hips that had initially been treated elsewhere, and in those classified as grade III. The clinical and radiographic results obtained for the hips treated surgically demonstrate poor results in 17% of the cases (6 out of 34), as a consequence of types III and IV osteochondrosis. It may be concluded that in this age group congenital hip dislocation is best treated by non-surgical reduction, possibly followed by surgery of the femur and acetabulum. Surgical reduction was only indicated when conservative methods failed.

Subcapital fracture of a congenitally dislocated hip: revival of Girdlestone resection arthroplasty.

A twenty-year-old, active male with a high congenital dislocation of the hip sustained a displaced subcapital fracture (accompanied by a comminuted transarticular fracture of the ipsilateral distal femur). Such a combination of injuries poses a challenging problem; the English literature does not cite any report describing the occurrence of subcapital fractures in congenitally dislocated hips. This article reviews the treatment options of the fractured neck of the femur, and the reasons for electing to perform a Girdlestone resection arthroplasty.

Right upper limb bud triplication and polythelia, left sided hemihypertrophy and congenital hip dislocation, facial dysmorphism, congenital heart disease, and scoliosis: disorganisation-like spectrum or patterning gene defect?

A Somali female baby with right upper limb triplication, polythelia, left sided hemihypertrophy, congenital hip dislocation, facial dysmorphism, congenital heart disease, and scoliosis is described. It seems that the above described pattern of anomalies has not been reported before. The possible developmental genetic mechanism responsible for this phenotype is briefly discussed.

[Acetabular component implantation in coxarthrosis due to dysplasia after high congenital hip dislocation].

A total of 71 (25-110) months after primary total hip replacement, 17 patients with high congenital hip dislocation and false iliac acetabulum were clinically and radiologically assessed. Twenty-one threaded cups were placed, 16 at the site of the true acetabulum, one at the site of the acetabular rim and four at the site of the false acetabulum. The Harris hip score increased from 37.1 (20.2-55.5) points preoperatively to 84.7 (67.4-97.7) points postoperatively. Radiologically there were no signs of cup migration. It can be concluded that even complicated dysplastic hips can be treated successfully by total hip replacement, without prior ileofemoral distraction or additional acetabular augmentation.

Open reduction of congenital hip dislocation. Advantages of the Ferguson medial approach.

Between 1974 and 1982, 56 hips of 51 children with congenital hip dislocation were treated by open reduction via the medial approach according to Ferguson. The mean age at operation was 7 (3-15) months. After 4 months of plaster cast immobilization, 41 hips had a normal acetabular index. Three hips required supplementary surgery: Salter's pelvic osteotomy in one case and a varus osteotomy in two cases. Of the remaining 53 hips, 26 received supplementary abduction treatment. During the first 2 years after reduction, 19 hips showed slight lateral displacement due to capsular laxity. The follow-up averaged 3 (0.5-8) years. All children older than 3 years now had stable, concentrically reduced hips without special treatment of the lateralization; in 9 of the 56 hips the acetabular roof was still dysplastic at follow-up. There was no difference in anteversion and neck-shaft angle between the treated and the contralateral hips. As vascular lesions were observed in only two hips and lateralization disappeared spontaneously, the Ferguson procedure seems safe.
