Femoral shortening and cementless arthroplasty in high congenital dislocation of the hip.

We performed cementless total hip arthroplasty with femoral shortening in 28 hips of 23 patients with high-riding congenital dislocation of the hip. All the acetabular cups were placed in their original anatomic location. If needed, the acetabulum was reconstructed using the femoral head. The proximal diaphyseal step-cut shortening osteotomy was performed and stabilized by cerclage or cable grips. The follow-up results at average 48 months postoperatively were scored clinically by the Merle D'Aubigné and Harris hip scores and were good and excellent in 89.2%. One acetabular cup showed progressive radiolucent lines suggesting aseptic loosening. Two superficial wound infections, 1 femoral nerve palsy, 1 sciatic nerve palsy, 2 nonunions, and 1 acetabular fracture were observed during the follow-up.

Dynamic ultrasound assessment for monitoring of treatment of congenital dislocation of the hip.

Of the 7,827 babies born in Sheffield between March 1989 and August 1991, a total of 114 (1.4%) who had either clinical abnormality of the hip or high-risk factors for congenital dislocation of the hip (CDH) were examined by ultrasound at birth and at regular intervals. Dynamic ultrasound assessment of both hips was done to diagnose instability and to monitor the treatment. Abnormal findings were recorded in 55 babies at the first visit, and 31 of these subsequently required treatment with the Pavlik harness (3.9 per 1,000). Only one case of late CDH has been seen among the babies who were not examined by ultrasound. There were no cases of avascular necrosis in our series. Dynamic ultrasound examination of high-risk infants' hips is a reliable method of screening for CDH. Monitoring of hips treated with the Pavlik harness, by dynamic ultrasound examination, can identify failure to obtain a concentric reduction, and in such cases, splintage can be abandoned in favour of other modes of treatment. It can, therefore, reduce the chances of overtreatment and its associated complications.

Development of acetabulum after closed reduction in developmental hip dysplasia.

The radiographic study of acetabulum development after closed reduction of 87 congenitally dislocated hips in 64 patients who were treated between 1980 and 1990 was conducted retrospectively. An average patient's age at the moment of closed hip reduction was 16 months (range between 6 to 24 months). On the average, patients were 16 months old (range between 6 to 24 months) at the moment of closed hip reduction. Development of bony acetabulum was followed for 8 years by measuring the AC angle. According to the age at the moment of closed reduction patients were sorted into three groups, the first group from 6 months to 12 months old (39 hips), the second group from 12 to 24 months old (28 hips) and the third group from 24 to 36 months old (20 hips). At the beginning of the treatment mean values of the AC angle in the first group were 37.2 degrees +/- 3.31 degrees; in the second group 39.7 degrees +/- 3.2 degrees; and in the third group 43.8 degrees +/- 2.7 degrees. The final values of the AC angle in the first group were 14.7 degrees +/- 3.21 degrees, in the second group 21 degrees +/- 3.02 degrees; and in the third group 24 degrees +/- 3.76 degrees. Normally and mildly dysplastic hips were achieved in 80.5% treated hips, while in 19.5% treated hips medium and serious dysplasia retarded. The acetabulum development in dysplastic hip after retained stable concentric reduction was the same as in the normal hip. The operative reconstruction of acetabulum should not be done before the third year of life.

Revision of failed open reduction of congenital dislocation of the hip.

We report a review of 33 hips (32 patients) which had required repeat open reduction for congenital dislocation of the hip. They were followed up for a mean of 76 months (36 to 132). Factors predisposing to failure of the initial open reduction were simultaneous femoral or pelvic osteotomy, inadequate inferior capsular release, and inadequate capsulorrhaphy. Avascular necrosis had developed in more than half the hips, usually before the final open reduction. At review, 11 of the hips (one-third) were in Severin grade 3 or worse; five had significant symptoms and only ten were asymptomatic and radiographically normal. Once redisplacement has occurred after primary open reduction, attempts to reduce the head by closed means or by pelvic or femoral osteotomy are usually unsuccessful and a further open reduction is necessary.
