Aims

Our aim was to assess the effectiveness of a protocol involving a standardised closed reduction for the treatment of children with developmental dysplasia of the hip (DDH) in maintaining reduction and to report the mid-term results.

Methods

A total of 133 hips in 120 children aged less than two years who underwent closed reduction, with a minimum follow-up of five years or until subsequent surgery, were included in the study. The protocol defines the criteria for an acceptable reduction and the indications for a concomitant soft-tissue release. All children were immobilised in a short- leg cast for three months. Arthrograms were undertaken at the time of closed reduction and six weeks later. Follow-up radiographs were taken at six months and one, two and five years later and at the latest follow-up. The Tönnis grade, acetabular index, Severin grade and signs of osteonecrosis were recorded.

We reviewed prospectively, after skeletal maturity, a series of 24 patients (25 hips) with severe acute-on-chronic slipped capital femoral epiphysis which had been treated by subcapital cuneiform osteotomy. Patients were followed up for a mean of 8 years, 3 months (2 years, 5 months to 16 years, 4 months). Bedrest with ‘slings and springs’ had been used for a mean of 22 days (19 to 35) in 22 patients, and bedrest alone in two, before definitive surgery. The Iowa hip score, the Harris hip score and Boyer’s radiological classification for degenerative disease were used.

The mean Iowa hip score at follow-up was 93.7 (69 to 100) and the mean Harris hip score 95.6 (78 to 100). Degenerative joint changes were graded as 0 in 19 hips, grade 1 in four and grade 2 in two. The rate of avascular necrosis was 12% (3 of 25) and the rate of chondrolysis was 16% (4 of 25). We conclude that after a period of bed rest with slings and springs for three weeks to gain stability, subcapital cuneiform osteotomy for severe acute-on-chronic slipped capital femoral epiphysis is a satisfactory method of treatment with an acceptable rate of complication.

Avascular necrosis is a serious complication of slipped capital femoral epiphysis and is difficult to treat. The reported incidence varies from 3% to 47% of patients. The aims of treatment are to maintain the range of movement of the hip and to prevent collapse of the femoral head. At present there are no clear guidelines for the management of this condition and treatment can be difficult and unrewarding.

We have used examination under anaesthesia and dynamic arthrography to investigate avascular necrosis and to determine the appropriate method of treatment. We present 20 consecutive cases of avascular necrosis in patients presenting with slipped capital femoral epiphysis and describe the results of treatment with a mean follow-up of over eight years (71 to 121 months). In patients who were suitable for joint preservation (14), we report a ten-year survivorship of the hip joint of 75% and a mean Harris hip score of 82 (44 to 98).

Valgus extension osteotomy (VGEO) is a salvage procedure for ‘hinge abduction’ in Perthes’ disease. The indications for its use are pain and fixed deformity. Our study shows the clinical results at maturity of VGEO carried out in 48 children (51 hips) and the factors which influence subsequent remodelling of the hip. After a mean follow-up of ten years, total hip replacement has been carried out in four patients and arthrodesis in one. The average Iowa Hip Score in the remainder was 86 (54 to 100). Favourable remodelling of the femoral head was seen in 12 hips. This was associated with three factors at surgery; younger age (p = 0.009), the phase of reossification (p = 0.05) and an open triradiate cartilage (p = 0.0007). Our study has shown that, in the short term, VGEO relieves pain and corrects deformity; as growth proceeds it may produce useful remodelling in this worst affected subgroup of children with Perthes’ disease.

After open reduction for developmental dysplasia of the hip (DDH), a pelvic or femoral osteotomy may be required to maintain a stable concentric reduction. We report the clinical and radiological outcome in 82 children (95 hips) with DDH treated by open reduction through an anterior approach in which a test of stability was used to assess the need for a concomitant osteotomy. The mean age at the time of surgery was 28 months (9 to 79) and at the latest follow-up, 17 years (12 to 25). All patients have been followed up until closure of the triradiate cartilage with a mean period of 15 years (8 to 23).

At the time of open reduction before closure of the joint capsule, the position of maximum stability was assessed. A hip which required flexion with abduction for stability was considered to need an innominate osteotomy. If only internal rotation and abduction were required, an upper femoral derotational and varus osteotomy was carried out. For a ‘double-diameter’ acetabulum with anterolateral deficiency, a Pemberton-type osteotomy was used. A hip which was stable in the neutral position required no concomitant osteotomy.

Overall, 86% of the patients have had a satisfactory radiological outcome (Severin groups I and II) with an incidence of 7% of secondary procedures for persistent dysplasia including one hip which redislocated. The results were better (p = 0.04) in children under the age of two years. Increased leg length on the affected side was associated with poor acetabular development and recurrence of joint dysplasia (p = 0.01). The incidence of postoperative avascular necrosis was 7%. In a further 18%, premature physeal arrest was noted during the adolescent growth spurt (Kalamchi-MacEwen types II and III). Both of these complications were also associated with recurrence of joint dysplasia (p = 0.01). Studies with a shorter follow-up are therefore likely to underestimate the proportion of poor radiological results.

The surgical treatment of Perthes’ disease by femoral or innominate osteotomy is not as effective in those over the age of eight years as it is in the younger child. This has prompted the search for other types of management in those who are older. The preliminary results of the use of a lateral shelf acetabuloplasty for such cases have shown encouraging results at two years. The concern with such an operation is that it might interfere with the growth of the outer aspect of the acetabulum and so prejudice the long-term outcome. We describe a review at maturity of 26 children presenting with early disease after the age of eight years who were treated by lateral shelf acetabuloplasty. The results suggest that the outcome is improved; 22 of 27 hips were rated as Stulberg groups 1 to 3. Poor results occurred in children, particularly girls, presenting with Group-4 disease over the age of 11 years.

We treated 37 infants with 53 idiopathic club feet by posterolateral release alone at a mean age of 2.4 months. They were reviewed after a mean follow-up of 10 years 7 months. Both function and appearance were studied. Seventeen feet had required further surgery, at an average of four years after posterolateral release. In all cases hindfoot equinus had been well corrected; the mean ankle dorsiflexion at review was 15 degrees. Most feet showed subtalar joint movement of between 50% and 75% of normal. Four feet showed poor results: one had a stiff subtalar joint, two feet in one child showed fixed forefoot varus, and one foot had required a Dillwyn-Evans operation at 5.5 years. The overall reoperation rate of 32% at ten years suggests that a radical release operation is not necessary in all patients. Of 59 patients who had only a simple posterolateral release 27 (46%) have satisfactory results.

Upper femoral osteotomy is a recognised treatment for selected patients with Perthes' disease. The results of this procedure were investigated at skeletal maturity in 44 patients (48 hips). The indication for operation was Catterall group II, III, and IV hips with 'head-at-risk' signs. Harris and Iowa scores were calculated clinically, and each hip was assigned radiographically to one of the five Stulberg classes, its initial Catterall grading checked and other relevant indices measured. Results showed excellent clinical function. Shortening was present in 14 hips (29%) and a positive Trendelenburg's sign was seen in 12 (25%). On radiographic assessment 58% of hips were Stulberg class I or II, with a good prognosis. The results of femoral osteotomy were better than those for conservatively treated hips in all age groups except those under five years.

It is now clear that vitamin K1 is part of a biochemical cycle that is essential for the conversion of specific bone peptides into a form that can bind calcium. We have used a recently described procedure for assaying vitamin K1 in plasma to test the involvement of this vitamin in fracture healing. Markedly depressed circulating levels were found in patients with fractures and the time taken for this level to return to normal appeared to be influenced by the severity of the fracture.

We report the clinical and radiographic results of the Chiari pelvic osteotomy in 49 hips (45 patients) at an average of 14 years after operation. Of these hips, over half had minimal or no pain, had good or excellent results as assessed by the Harris hip score, and could walk at least three miles; three-quarters, however, had a positive Trendelenburg sign. A younger age at operation and a painless hip with no radiographic evidence of degeneration before operation were associated with a higher hip score at review. The percentage of hips without degenerative changes fell from 68% before operation to 15% at final review. There were no major complications and it was found that a Chiari osteotomy need not interfere with normal childbirth.

Forty-four patients who had undergone 50 capsular arthroplasties for congenital dislocation of the hip were reviewed after a mean follow-up of 20 years. Their average age at operation was 5.9 years; 31 of the operations were undertaken because of late presentation, the remainder because of the failure of previous surgery. In all, 70% of the hips showed good function despite a reduced range of movement, but patients with bilateral arthroplasties fared poorly. Excellent containment within the acetabulum was found in 80%, but the femoral head was always abnormally high though not unduly lateral or medial. This configuration had remained unchanged during follow-up. The accuracy of reduction along the mediolateral axis was the only variable found to influence the outcome significantly. Functional deterioration, associated with pain, was noted to be more common after 20 years than before, and was associated with radiographic evidence of joint degeneration.

Eleven patients with tears of the acetabular labrum are discussed and the syndrome of the torn labrum is defined. In all cases the lesion was associated with acetabular dysplasia, and a constant early radiological sign was a cyst in the lateral aspect of the acetabulum. The diagnosis was confirmed by arthrography. It is suggested that these tears are degenerative, occurring as a consequence of abnormal stresses imposed by the uncovered lateral portion of the femoral head. Once a tear is present a localised stress point occurs on the femoral head, leading rapidly to degenerative arthritis.

Hinge abduction is an abnormal movement of the hip which occurs when a femoral head, deformed as a result of avascular necrosis or Perthes' disease, fails to slide within the acetabulum. Patients with this condition present with pain and shortening and in some cases arthrodesis has been recommended. We report 27 cases in which the diagnosis had been established by arthrography. The satisfactory results of abduction-extension osteotomy of the femur in 26 hips with this condition are reported.

Dorsiflexion has been studied in three normal feet and in three feet with talipes equinovarus to determine the anatomical features which might contribute to the failure of operative treatment to correct the deformity. In the normal feet the movement of dorsiflexion was found to be essentially rotatory in nature and not simply hinging; as dorsiflexion proceeds the fibula moves forwards relative to the os calcis and the calcaneal tendon. In the club feet a posterolateral tether was found; this prevented fibular movement and blocked dorsiflexion. As a result of this study a posterior and lateral release is advocated for the operative correction of the hindfoot in a child with a club foot deformity, particularly under the age of a year.

There are differences of opinion about the pathogenesis of Perthes' disease. All are agreed that it is due to ischaemia, but the cause of this and the size and number of infarctions are in dispute. Through the generosity of the contributors six whole femoral heads and core biopsies of five other cases have been studied radiographically and histologically. The findings ranged from an ischaemic arrest of ossification in the capital articular cartilage without infarction to multiple complete infarctions of the epiphysial bone. The ensuing reparative process contributes to the pathology, which is of a range to warrant grading or grouping.

Eighty-four children suffering from Perthes' disease are reviewed. The policy of management for these patients was one by which 55 per cent of the cases had no active treatment and the remainder were treated by operation. Results of the series show an improvement over a previously reported series of untreated controls, particularly where clinical management had been possible throughout the disease process. The importance of early definitive treatment for Group 4 cases is stressed. It is concluded that in the early stages where "head-at-risk" signs are not present, treatment may be conservative. Should these signs develop later the long-term result is not prejudiced if operative treatment is undertaken promptly.

We compared 63 hips (Catterall Groups 3 and 4) contained by femoral osteotomy with 85 untreated hips and found that 50.7 per cent of treated patients developed congruous spherical femoral heads in contrast to 14.1 per cent of those untreated. We have also considered certain other features relevant to the outcome. We suggest that the indications should not be modified on the grounds of early age of onset. Relief from weight-bearing does not appear to improve the results of containment. We have assessed the shortening which follows femoral osteotomy and conclude that this is only significant when there is growth disturbance at the capital epiphysis. These changes are at least as frequent in untreated patients.

We have considered the reasons for securing containment of the femoral head in Perthes' disease and have reviewed briefly the methods used. The present investigation describes the outcome in a controlled series of forty-eight hips treated by containment by femoral varus-rotation osteotomy in selected patients. In assessing the results we have emphasised that controls are essential, and for this purpose we have used two comparable groups, one untreated and the other treated by methods other than containment. The same factors were considered in assessment--namely age, duration, group, and the presence or absence of "at risk" signs. The results were graded similarly as good, fair and poor in all groups. We have concluded that containment by femoral osteotomy is the treatment of choice in patients with "at risk" signs provided that severe deformity has not already occurred. There is no evidence that treatment of any kind favourably influences the course of the disorder in the remainder. Although this is predominantly a radiological study some clinical features are discussed.

1. Further consideration has been given to the lateral rotation which occurs at the ankle joint in uncorrected club feet.

2. Medial rotation osteotomy of the tibia may be used to restore more normal alignment to the hind foot at the expense of an increase in varus of the forefoot, which must be corrected at a second operation.

3. The early results in seven feet treated in this manner are reported.

4. We hope that this paper will be regarded more as a contribution to the understanding of the anatomy of uncorrected club foot than as advocacy of a new method of surgical treatment.

1. Eighty-nine cases of Perthes' disease are reviewed.

2. The prognosis varies with the amount of the epiphysis involved.

3. It is possible to assess the amount of epiphysial involvement by a study of the early radiographs. Cases were allocated to four groups on this basis.

4. It is confirmed that both sex and age at the time of diagnosis influence the final prognosis. The reasons for this are discussed.

5. The concept of "the head at risk" is suggested and radiological signs described to diagnose such cases.

6. It is hoped that the classification suggested may in future act as a basis for comparisons of treatment.

1. We have considered torsional deformity in club feet and conclude that medial torsion does not occur in the tibia.

2. It is suggested that in uncorrected feet the hindfoot with the ankle mortise is laterally rotated.

3. We have discussed the cause, prevention and consequences of spurious correction by lateral rotation.

4. The "bean-shaped foot" seems an appropriate description of the final deformity as it is commonly seen.
