1. The movements of the talus are described with particular reference to the anatomy of congenital talipes equinovarus. 2. It is suggested that the fundamental deformity in severe club foot is the fixed plantar-flexion of the talus. 3. Early operation is advised whenever serial stretching fails to bring the heel quickly into its normal position

1. The surgical management of two children with congenital hypoplasia of the upper end of the femur is described. 2. Early exploration is advocated to establish the nature and extent of the anomaly and to attempt its correction. 3. The preliminary results are sufficiently encouraging for us to recommend that further attempts at surgical treatment be considered in patients with this disorder

1. Eight cases of congenital vertical talus in infancy are reported. The principal differential diagnosis at this age is from talipes calcaneo-valgus. 2. The deformity is primarily a dorsal dislocation of the talo-navicular joint. 3. Closed reduction can be achieved if treatment begins at birth. Open reduction is indicated for the deformity uncorrected by the age of three months

The outcome in 83 patients with congenital clubfoot was evaluated at a mean age of 64 years using three validated questionnaires assessing both quality of life (short-form (SF)-36 and EQ-5D) and foot and ankle function (American Academy of Orthopaedic Surgeons (AAOS) Foot and Ankle questionnaire). In SF-36, male patients scored significantly better than male norms in seven of the eight domains, whereas female patients scored significantly worse than female norms in two of the eight. Male patients scored better than male norms in both the EQ-5D index (p = 0.027) and visual analogue scale (VAS) (p = 0.013), whereas female patients scored worse than female norms in the VAS (p < 0.001). Both male and female patients had a significantly worse outcome on the AAOS Core Scale than did norms. There was a significant correlation for both genders between the SF-36 Physical Component Summary Score and the AAOS Core Scale. The influence on activities of daily life was limited to foot and ankle problems in all patients, and in females there was an adverse effect in physical aspects of quality of life

We reviewed the cases of 38 children with 45 congenitally dislocated hips who presented for primary treatment after the age of three years. Of these, 34 hips were managed by the 'direct approach' of Somerville and Scott (1957); 14 of these required secondary operations for subluxation, often with a poor outcome. Eleven hips were treated by combined pelvic and femoral osteotomy which, in general, gave good results. At a mean follow-up of 16.7 years, 80% of the whole series had a good or excellent clinical result and 51% were good or excellent radiologically. Simultaneous correction both above and below the hip is considered to be the best treatment for the older child with congenital hip dislocation

An alternative to Syme's amputation for congenital absence of the fibula is described in this paper. Nine children have had the ankle reconstructed using the Gruca technique with a very satisfactory result in eight. This procedure is not suitable for every patient and in most unilateral cases the operation can only be regarded as an interim procedure because of progressive leg-length inequality. The decision to remove the foot may be delayed and it allows childhood to be spent without resort to prostheses. However, the procedure can be considered as the definitive operation in cases of bilateral deformity

1. A survey of genetic and other etiological factors has been carried out in 589 index patients with congenital dislocation of the hip and their families, with special investigation of acetabular dysplasia, familial joint laxity and a comparison of neonatal and late-diagnosis cases. 2. It is believed that there are two etiological groups with congenital dislocation of the hip, i) a group with acetabular dysplasia which is inherited as a multiple gene system and is responsible for a high proportion of cases diagnosed late, and ii) a group with joint laxity which is responsible for a high proportion of neonatal cases. 3. Evidence is presented to show that acetabular dysplasia is a separate heritable system in some families. 4. Other findings relating to the genetic aspects of the survey are summarised

1. The histories of 149 patients, coming to the Hospital for Sick Children within the first three years of life with congenital dislocation of the hip (191 dislocated hips), and treated by conservative methods, have been reviewed. 2. The patients with unilateral dislocations (107) have been divided into three groups, according to the angle of slope of the opposite acetabulum. This angle was measured on the first radiograph and related to the mean value for age and sex. 3. The opposite hip was classed as "normal" if the acetabular angle was below or within one standard deviation above the mean for sex and age; as "moderately shallow" if it was between one and two standard deviations above the mean; and as "shallow" if it was over two standard deviations above the mean. This grouping was found to have a direct bearing on the results of conservative treatment in unilateral cases. a) Those with "normal" opposite acetabula–accounting for most of the unilateral cases–responded well. b) Those with "moderately shallow" opposite acetabula responded variably. c) The group with "shallow" opposite acetabula usually failed to respond. 4. Most bilateral dislocations behaved as unilateral dislocations with shallow opposite hips. 5. Additional factors influencing the response to conservative treatment–sex, age at first attendance, family history, fragmentation of the femoral epiphysis and eccentric reduction–are discussed

Based on the constancy with which the limbus is inverted into the joint in a typical congenital dislocation of the hip, a hypothesis is presented which suggests that the sequence of events leading to established dislocation is: 1) lateral rotation aided and abetted by anteversion; 2) extension of the hips causing subluxation; 3) dislocation and inversion of the limbus; 4) secondary changes in the upper end of the femur, pelvis and acetabulum which will also develop if the deformity does not progress beyond a subluxation. A pen picture is drawn showing how anteversion is either moulded away during growth to produce a normal hip, or persists with or without dislocation. The fate of the persistently inverted limbus is discussed and a line of treatment based on these findings is briefly considered

We have assessed the reliability of four classification systems for club foot. Four observers evaluated nine children (18 feet) at different stages in the first six months of life, a total of 180 examinations. Each observer independently assessed all feet according to the classification systems described by Catterall, Diméglio et al, Harrold and Walker, and Ponseti and Smoley. The variation between observers was assessed using the kappa test which for no more agreement than chance has a value of 0, and for complete agreement between observers a value of 1. The kappa values varied between 0.14 and 0.77 depending on which classification system was used. The system of Diméglio et al was found to have the greatest reliability. Our findings suggest that current classification systems for the analysis of congenital talipes equinovarus are not entirely satisfactory

1. Six thousand consecutive newborn babies were personally examined by the author for congenital dislocation of the hip. Twenty-four cases were diagnosed and twenty-three treated. 2. Twenty-two of the twenty-three treated cases had excellent results after treatment in the von Rosen splint. 3. The baby should be five days old before a final decision is made as to whether treatment is necessary. 4. A further twenty-seven babies were found to have unstable hips. Eighteen of these were followed up and all were found to have developed normally without treatment. 5. The technique of examination is simple and quick but it is desirable that it should be carried out in each maternity unit by only one or two doctors

We used the Ilizarov method in seven patients with severe congenital radial club hands who had had previous wrist surgery, to correct residual shortening and bowing of the ulna together with recurrent wrist deformity. The mean age at operation was 6.5 years. The mean ulnar shortening was 5.3 cm and the mean angular deformity 42°. The mean length gained was 51% of the original ulna. The mean healing index was 46.9 days (29.8 to 64.0). The ratio of the length of the lengthened ulna to the normal side improved on average from 64% to 95%. The angular deformity was initially completely corrected in six out of seven patients. The length ratio, however, decreased to 83% at the final follow-up. In four patients, the angular deformity partially recurred. We recommend correction of congenital radial club hand by staged procedures. The first is centralisation and stabilisation of the wrist and the second lengthening of the ulna and correction of the angular deformity using the Ilizarov method

We describe a new technique for examining the infant hip using ultrasound. Both hips are imaged simultaneously via an anterior approach. The examination can be done with the hip either extended or flexed and abducted. The method has three advantages: 1) since both hips are imaged simultaneously, lines can be drawn to assist in determining the relationship between the femoral head and the pelvis; 2) proximal, anteroposterior and lateral displacement of the femoral head can all be demonstrated; 3) the method is applicable to the infant in a harness or a plaster cast to demonstrate maintenance of reduction of a dislocated hip. The usual direction of dislocation of the femoral head was anterior and lateral. Proximal migration was also observed in cases with more severe dislocation. In flexion, the dislocated head of the femur often moved posterior to the acetabulum. Of 1276 hips, in 638 infants aged from three weeks to one year, 49 showed congenital dislocation. The accuracy of our anterior method of sonography in diagnosing congenital dislocation of the hip compared well with the method of Graf and with radiography

The case histories of two brothers with congenital defects of the tibia and neurofibromatosis are presented. This report of congenital pseudarthrosis of the tibia in siblings is believed to be the first in the English literature

1. The technique of arthrography in congenital displacement of the hip is described. No complications have been encountered in a series of over 200 examinations. The interpretation of the arthrographs is discussed. 2. It is suggested that the abnormal hips may be classified in three degrees: 1) Primary instability; 2) partial displacement without interposition of soft tissue; 3) complete displacement with interposition of soft tissue between head and socket. 3. Two types of complete displacement or dislocation are recognised: 1) the "tight" dislocation; 2) the "loose" dislocation. In the latter there is marked displacement of the femoral head, and arthrography done before reduction demonstrates interposition of a fold of capsule lying in front of the inverted limbus. 4. Arthrography is of special help in making the diagnosis between partial displacement with eversion of the labrum and "tight" dislocation with an interposed limbus. It is helpful too in establishing the cause of failure of reduction

1. The danger of fracture and subsequent pseudarthrosis in congenital anterior bowing of the tibia is emphasised. The fate of seven such patients is described. 2. With the object of preventing fracture, early and urgent bone grafting is advocated

The management of a personal series of over 500 patients with congenital hip dislocations has been reviewed with special reference to the mistakes that have been made and the safeguards which have now been adopted

1. The occurrence of congenital discoid medial cartilages in two patients is reported: in one the abnormality was bilateral. The three specimens are described and illustrated. 2. The literature on the subject is reviewed and the specimens discussed and classified

1. A case is described of bilateral congenital contracture of the ilio-tibial bands in a healthy girl of ten months. 2. With the hips extended each lower limb was held in about 25 degrees of fixed abduction. 3. Division of the ilio-tibial bands abolished the abduction contractures

The frame described has a place in the treatment of congenital dislocation of the hip especially if the diagnosis is not made until after the age of one year. Analysis of comparable series of hips reduced on the frame and by manipulation shows that dysplasia of the femoral head is decidedly commoner after the manipulative method
