TREATMENT OF CONGENITAL DISLOCATION OR SUBLUXATION OF THE HIP IN CHILDREN OVER THE AGE OF THREE YEARS
Authors: Eyre-Brook A. L. 
Published: February 2018

1. A small personal consecutive series of children with congenital dislocation or subluxation of the hip who came for treatment at the age of over three years has been reviewed. The children have been kept under review up to the age of ten years or more. 2. A number of late results are illustrated. They lead to the conclusion that open operation is indicated in all these cases and that acetabuloplasty will effectively provide stability in most, particularly when combined with osteotomy of the femur with adduction angulation and lateral rotation. 3. It is still too early to assess the value of pelvic osteotomy of the Salter (1961) or Chiari (1955) type. 4. Capsular arthroplasty appears from Trevor's (1960) considerable experience to have a valuable place in patients over six years old.
BONE FORMATION IN PAGET'S DISEASE
Authors: Lee W. R. 
Published: February 2018

1 . Normal and diseased bone was obtained by biopsy from five patients suffering from Paget's disease. The tissue was studied by histology, microradiography and quantitative fluorescence microscopy using tetracycline markers. Study of the morphological changes showed that two of the biopsies could be regarded as normal, while one was osteoporotic; two biopsy specimens were in the porotic phase of Paget's disease and the remaining five were in the sclerotic phase. 2. The tetracycline markers were used to measure the linear rate at which bone was deposited on individual surfaces (appositional growth rate) in µ per day and the percentage volume of new bone added to the total volume of bone per day (bone formation rate). The values obtained for appositional growth rate in all the biopsies were of the order of 1 µ per day, but slightly higher values were obtained in the diseased tissue of each individual. The bone formation rate in normal bone from the proximal femur was about 0·04 per cent per day, about 0·13 per cent per day in the porotic phase, and about 0·4 per cent per day in the sclerotic phase of Paget's disease. 3. Although these values must be accepted with some reservation, there seems to be no doubt that there is an upper limit of about 1 µ per day to the rate of deposition of bone on an individual bone surface; this suggests that in Paget's disease the osteoblast behaves as a normal cell.
THE PATTERN OF AGEING OF THE ARTICULAR CARTILAGE OF THE ELBOW JOINT
Authors: Goodfellow John W. , Bullough Peter G. 
Published: February 2018

1. The age changes in the articular cartilage of the elbow joint are presented from a study of twenty-eight necropsy subjects aged eighteen to eighty-eight years. During early adult life those areas of cartilage which do not usually articulate with opposed cartilage always show some degree of chondromalacia. 2. Evidence is presented that the almost inevitable degeneration of the radio-humeral joint in old age is related to the combination of rotation and hinge movements that occur at that joint. This is in marked contrast with the relative immunity of the humero-ulnar articulation which has hinge movement only.
COMPLICATED CRUSHING INJURIES OF THE PELVIS
Authors: Froman Colin , Stein Archie 
Published: February 2018

1. Seventy-five patients sustained fractures of the pelvis with associated soft-tissue complications. Twenty died, and of these, thirteen died within forty-eight hours of admission to hospital. 2. The initial resuscitation and clinical assessment of these patients are discussed, and attention is drawn to the significance of the concomitant retroperitoneal haematoma as a cause of oligaemic shock, and as a dissembler of internal visceral injury. 3. The morphological fracture patterns are classified into six categories, but the fracture patterns are not correlated with specific visceral injuries. 4. Forty-six patients sustained urinary tract injuries. Of these, nineteen had suffered rupture of the urethra; fourteen had rupture of the bladder; two had both urethral and vesical disruption, and one patient had a torn ureter. The diagnosis and management of these injuries is discussed. 5. Twelve patients had a traumatic laceration or perforation of the ano-rectum. Nine of these patients had associated urethral or vesical injuries. 6. Four patients were involved in accidents and sustained pelvic fractures while in the last three months of pregnancy. The tragic outcome of this combination of circumstances is noted. 7. Attention is drawn to peripheral nerve injuries in association with pelvic fractures, and the difficulty of localising these lesions is stressed. 8. Eight instances of damage to the abdominal parietes are recorded. Four patients suffered skin and soft-tissue loss, two patients had diaphragmatic disruptions and two patients had abdominal wall dehiscences. 9. Major accident victims frequently have multiple injuries. This series of patients has been analysed to draw attention to the association of pelvic fractures with bizarre visceral injuries.
UNILATERAL FACET INTERLOCKING IN THE LOWER CERVICAL SPINE
Authors: Braakman R. , Vinken P. J. 
Published: February 2018

Bilateral interlocking of the articular facets of the cervical spinal column results from excessive flexion. Unilateral interlocking (hemiluxation) results from simultaneous excessive flexion and rotation. Patients with hemiluxation of the cervical spine often have only mild complaints and the clinical signs may be slight. The diagnosis is made radiologically, but it is often overlooked. Various forms of treatment may give good results. In recent hemiluxation, reduction is advisable to promote recovery of radicular symptoms. The effect of reduction on spinal cord symptoms is uncertain. Manual reduction under general anaesthesia is usually successful, with the possible exception of some cases of interlocking at C.6-C.7, or C.7-T.1. Skull traction with weights of 5 to 10 kilograms even when prolonged is hardly ever successful; with weights of 10 kilograms or more there is a chance of success. Surgical reduction is not always necessary. A hemiluxation of more than two weeks' standing may still be reduced but non-operative methods offer little chance of success. In this series there has been no aggravation of the neurological deficit after reduction. Although hemiluxation shows a tendency to spontaneous stabilisation it is wise in our opinion to apply some form of fixation. The selection of the method of fixation depends on the neurological picture and on the estimated degree of instability. The latter depends on the presence or absence of additional damage to the interlocked and adjacent vertebrae. Manual reduction by means of traction in the longitudinal axis of the cervical spine under general anaesthesia with muscle relaxation, followed by immobilisation in a plaster jacket (Minerva type) for three months is successful in many cases. If surgical stabilisation is considered necessary an attempt at manual reduction should be made before operation so that when the patient is placed on the table the cervical spinal canal has regained its normal shape. In general, sufficient stability will have been achieved after approximately three months, so that for hemiluxations of more than three months duration surgical treatment will only rarely be necessary. Figure 11 shows the methods of treatment that we advise.
EPIPHYSIAL STAPLING AND LEG EQUALISATION
Authors: Poirier H. 
Published: February 2018

1. Thirty-three patients who had had stapling of the lower femoral and upper tibial epiphysis to correct inequality of the leg lengths were reviewed after maturity. The staples were inserted so that correction of the disparity would coincide with termination of growth. 2. The predicted corrections were found to be inaccurate. The error was 47 per cent in girls operated on between ten and twelve and 51 per cent in boys between ten and thirteen. In older children the prediction was more accurate. 3. Despite the inaccuracy of prediction only four patients were left with shortening of more than 3·5 centimetres. 4. Complications of the operation were deformity, ligamentous laxity, subjective symptoms and necessity for further operation. 5. Only one girl had a serious deformity–genu recurvatum of 25 degrees. Half the patients had minor degrees of hyperextension. 6. The causes of the complications are discussed and suggestions made how their incidence might be reduced. 7. It is concluded that the operation of stapling the epiphyses around the knee of the long leg has a small but useful part to play in the correction of inequality of leg lengths. It should be confined to tall boys over thirteen and girls over twelve.
THE PROGNOSIS IN ZOSTER PARALYSIS
Authors: Gupta S. K. , Helal B. H. , Kiely P. 
Published: February 2018

1. Forty-five cases of zoster paralysis, not involving the cranial nerves, are detailed. These include eighteen cases not previously published. Of these eighteen patients, one-third were referred for an orthopaedic opinion. 2. Complete or almost full recovery occurred within a year in two-thirds of the patients. Permanent paralysis occurred in one-sixth of the patients studied. 3. Muscles that failed to recover were mainly or wholly supplied from single segments of the spinal cord; so the prognosis must be guarded in those cases in which such muscles are completely paralysed. 4. Various phenomena occurring in zoster paralysis are discussed.
TWO-LEVEL FRACTURES OF THE TIBIA
Authors: Zucman J. , Maurer P. 
Published: February 2018

1. Intramedullary nailing in two-level tibial fractures provides the following advantages: it allows walking with full weight-bearing in an average time ofthree to four months; it decreases the rate of non-union ; it decreases the rate of malunion ; it should decrease the rate of infection in closed fractures when compared with other types of internal fixation, due to the technique of blind nailing without exposure of the fracture site. 2. Compound tibia! fractures treated by nailing are still often complicated by infection. Nevertheless, we have not been able to find studies in the literature based on series large enough to permit the conclusion that other methods could lower significantly the infection rate.
NIEVERGELT-PEARLMAN SYNDROME
Authors: Dubois H. J. 
Published: February 2018

1. A case of massive tarsal synostosis with supination of the forefeet, synostosis in the carpus with brachydactylia, clinicocamptodactylia, symphalangism and dysplasia of the elbows is presented. 2. This conforms to the description by Nievergelt (1944) and Pearlman et al. (1964).
ARTHROGRYPOSIS MULTIPLEX CONGENITA
Authors: Lloyd-Roberts G. C. , Lettin A. W. F. 
Published: February 2018

1. We have reported our experience in fifty-two patients with arthrogryposis multiplex congenita. 2. The nature of the disorder, its possible cause, the clinical features and differential diagnosis are discussed. 3. Early management is described with special reference to the infant, his parents, and general principles of selection and timing. The treatment of the individual deformities which commonly occur is outlined. 4. We have emphasised that lower limb deformities should be treated vigorously in the first year, whereas in the upper limb treatment is better delayed until an accurate assessment can be made. 5. Correction in the young child should be by soft-tissue release rather than by osteotomy. 6. Prolonged splinting after operation is necessary. 7. Severe weakness may dominate the problem and make operation unrewarding. 8. The intelligence, determination and adaptability of these children flatters even modest surgical success.
GEOGRAPHICAL VARIATIONS IN SENILE OSTEOPOROSIS
Authors: Chalmers J. , Ho K. C. 
Published: February 2018

1. Using the incidence of hip fracture as an indication of senile osteoporosis, the occurrence of this disease is found to vary greatly in different racial groups. The highest reported incidence is in Sweden, followed by Britain, Hong Kong Chinese, Singapore Chinese and South African Bantu, in that order. Likewise, the sex incidence varies, women outnumbering men in Sweden and Britain, men exceeding women in Singapore; an equal sex incidence is found in Hong Kong. 2. In all races and in both sexes the incidence is more closely related to age than any other factor, a progressive increase being noted after forty-five. Ageing is clearly the dominant etiological factor, but this does not explain the different racial incidence. These differences cannot be attributed to hormonal state or to the dietary intake of calcium, but do accord in general with the living standards of the different countries and the degree of physical activity undertaken by the different populations and sexes. 3. Hereditary factors may play a part, but further geographical study of the incidence of senile osteoporosis is necessary before the relative importance of inheritance and environment can be assessed.
DISTURBED EPIPHYSIAL GROWTH AT THE KNEE AFTER OSTEOMYELITIS IN INFANCY
Authors: Roberts P. H. 
Published: February 2018

1. Fifteen patients who had had osteomyelitis of the lower femur or upper tibia during infancy have been studied. The cases of four patients showing particular features of the disease are presented in detail and the remainder are summarised. 2. It is suggested that damage to the epiphysis may be due to an abscess, or to ischaemia following occlusion of the blood supply. In the latter instance the prognosis may be better. 3. In the early stages the radiographic appearances may be deceptive, suggesting that damage to the epiphysis is irreparable. 4. Significant recovery of the epiphysis may occur in some patients after a delay of several years. This, together with the often good function which is preserved at the joint, should deter the surgeon from early destructive operation on the limb. 5. Deformity, which was present to some extent in all cases, appeared early and was not well controlled by conservative treatment. Operations were performed in twelve patients. 6. Shortening of the limb occurred in all patients and in some it was severe.
ACETABULAR DYSPLASIA AND FAMILIAL JOINT LAXITY: TWO ETIOLOGICAL FACTORS IN CONGENITAL DISLOCATION OF THE HIP
Authors: Wynne-Davies Ruth 
Published: February 2018

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.
PRIMARY PROTRUSION OF THE ACETABULUM
Authors: Hooper Jonathan C. , Jones E. Wyn 
Published: February 2018

1. A study of fifty-nine patients with protrusion of the acetabulum showed that they fell into three age groups: those in their teens, those aged thirty-five to fifty years, and those presenting from fifty-one years onwards. 2. The juvenile age group was investigated clinically and biochemically but no causative metabolic factor was found. 3. The familial incidence was confirmed by radiological and biochemical surveys of several families. 4. The results of treatment show that when conservative treatment is insufficient a total hip replacement gives the best result from operation.
PLATE FIXATION OF TIBIAL SHAFT FRACTURES
Authors: Burwell H. Nevile 
Published: February 2018

1. One hundred and eighty-one fractures of the tibial shaft were treated by rigid fixation using conventional plates. 2. Comparison is made with series of fractures treated by the closed method. 3. The incidence of non-union, or delayed union requiring a long period of plaster immobilisation, was found to be less with the open method of treatment. 4. Plating was also found to give better functional results with a shorter period of disability except in severe open fractures. 5. Plating is a valuable method of treatment for tibial fractures in the elderly.
DISPLACED FRACTURES OF THE NECK OF THE RADIUS IN CHILDREN
Authors: Jones E. R. L. , Esah M. 
Published: February 2018

1. Thirty-four cases of displaced fracture of the neck of the radius in children are reviewed with special reference to elbow and forearm function. 2. There were eight poor functional results-four after eighteen closed reductions and four after sixteen open reductions. 3. The causes of the poor functional results are recorded and the complications discussed. Union in a displaced position was the main cause of restricted movement. Deformity of the radial head due to avascular necrosis, and fibrous adhesions between the neck of the radius and the ulna, were other factors. 4. Fractures that were held reduced by Kirschner wires had better results than comparable fractures treated by closed reduction or op en reduction without fixation. 5. It is concluded that all fractures, whatever the age of the child, with angular displacement exceeding 15 degrees need accurate reduction. Closed reduction is not easy, and repeated check radiographs are needed to ensure maintenance of reduction. Certain of these fractures are unstable and require internal fixation with Kirschner wires.
POSTERIOR RIB RESECTION IN SCOLIOSIS
Authors: Piggott Harry 
Published: February 2018

1. The production of scoliosis in young animals by resection of the posterior ends of the ribs is described and the etiological mechanisms discussed. It is suggested that retardation of posterior rib growth, removal of mechanical support from one side of the spine, and disturbance of proprioceptive impulses are the factors which initiate the deformity. 2. Some or all of these mechanisms may contribute to the production of certain human curves, for instance impaired rib growth and support in post-poliomyelitic deformities, proprioceptive and reflex disturbances in syringomyelia. 3. Therapeutically resection of the heads and necks of the ribs on the concave side of thoracic idiopathic curves is followed by improvement in some cases. Exactly how much improvement, in what proportion of curves, and for how long it will be maintained cannot be defined at present, but therapeutically worthwhile effects have been obtained, especially in children under five years old; even if this improvement is followed by later progression, several years of freedom from bracing may have been achieved, and the operation has not in any way interfered with subsequent correction and posterior fusion if this has seemed necessary. It is thought that this operation may have a small but useful role in the early management of idiopathic scoliosis, especially in a young child who is not responding well to bracing.

Published: February 2018

1. Fifty tibial fractures treated by intramedullary nailing during seven years have been presented. There were twenty-eight closed and twenty-two open fractures. 2. The use of the method for treating open (compound) fractures is discussed. 3. The indications for intramedullary nailing are outlined.
DiFFICULTIES OF EARLY DIAGNOSIS AND TREATMENT OF CONGENITAL DISLOCATION OF THE HIP IN NORTHERN IRELAND
Authors: Williamson Jean 
Published: February 2018

1. In Northern Ireland a campaign to eradicate congenital dislocation of the hip by neonatal demonstration of abnormal laxity and early splintage has been reviewed. The number of live births in the area covered is approximately 30,000 per annum. 2. The results to date suggest that the problem has been greatly over-simplified. The number of established dislocations has not fallen appreciably. 3. Failures have occurred both in early diagnosis and in early treatment. 4. To help close the diagnostic net all children should be screened again during the first year. Infants born by breech presentation and infants with a family history of dislocation should have radiographs taken in the early months, even if clinical tests are negative. 5. With regard to neonatal treatment, early splintage has failed to prevent established dislocation in about 2·4 per cent of the hips so treated. How to detect such resistant cases is an important problem.
LOW-FRICTION ARTHROPLASTY OF THE HIP FOR THE FAILURES OF PREVIOUS OPERATIONS
Authors: Dupont Joseph A. , Charnley John 
Published: February 2018

1. Two hundred and seventeen low-friction arthroplasties performed between November 1962 and April 1969 in 203 patients with failed previous operations have been analysed. 2. The technical details of operation in relation to these conversion problems have been outlined. 3. The quality of the results in relation to pain, mobility and ability to walk has been assessed before operation and one year afterwards, with small numbers at three and five years. 4. Pain was completely relieved or was minimal in 96·3 per cent of the patients, and in no case was the pain worse. 5. The total range of movement was 100 degrees or more in 98·5 per cent. No hip lost movement after conversion. 6. The failures were principally due to infection and to technical difficulties. There were no mechanical failures without a technical or radiological explanation. 7. Low-friction arthroplasty is an excellent salvage procedure, especially for failed cup arthroplasty.
SPINAL OSTEOTOMY FOR SEVERE KYPHOSIS IN CHILDREN WITH MYELOMENINGOCELE
Authors: Eckstein H. B. , Vora R. M. 
Published: February 2018

1. Kyphosis and kyphoscoliosis associated with myelomeningocele are discussed. 2. It is suggested that the condition be treated by osteotomy of the spine, with removal of one or more vertebral bodies. 3. Sixteen patients treated by this method of spinal osteotomy are presented. 4. Although almost a third of the patients died, a high operative and post-operative mortality in this condition is considered acceptable.
CONGENITAL ELEVATION OF THE SCAPULA
Authors: Cavendish M. E. 
Published: February 2018

1. One hundred cases of congenital elevation of the scapula are reviewed; thirty-four were treated by operation. 2. A method of grading of appearance is suggested to assist in selecting cases for operation. 3. In very mild cases operation does not confer worthwhile benefit. 4. Very severely affected patients cannot be made to look normal. 5. The appearance often deteriorates during a period of rapid growth of the neck, making continued observation and reassessment essential. 6. The primary aim of treatment is to improve appearance; improvement in function is uncertain. 7. Excision of the supero-medial part of the scapula, and of the omo-vertebral bone when present, is recommended in most cases requiring operation. It is safe and simple, with little risk of loss of function and with simple after-treatment.
