SYNOVECTOMY FOR RHEUMATOID ARTHRITIS
Authors: Wilkinson M. C. , Lowry J. H. 
Published: February 2018

1. The follow-up reports of ninety-one joints affected by rheumatoid arthritis and treated by synovectomy showed that seventy-three joints remained free of pain. Forty-nine out of ninety-one joints retained useful function after a period averaging three and a half years. 2. The average duration of the disease before admission was eight and a half years. 3. The joints causing most distress were selected for operation. Better results might have been obtained if these patients had received constitutional treatment, splintage and synovectomy earlier. Many of these patients had advanced disease which was continuing to advance at the time of their admission, in spite of previous treatment. Many accepted a trial of treatment in a long stay hospital as a last hope. 4. The return of forty-eight out of sixty-two patients to unassisted or nearly unassisted activity and the maintenance of this state in thirty-nine out of fifty-four shows that the success of the pilot scheme conducted in cooperation with Dr W. S. Tegner and Dr R. M. Mason of the London Hospital has been confirmed by further experience.
TIBIO-FIBULAR RELATIONSHIP IN PARALYSED LIMBS
Authors: Makin Myer 
Published: February 2018

1. A survey of 112 cases of residual poliomyelitis with leg shortening of 2·5 centimetres or more is reported. 2. In eighty-seven patients paralysed in early infancy the fibular shortening was greater than the tibial shortening. 3. The absence of the normal "to and fro" motion of the fibula causes delay in the appearance of the fibular epiphyses and retards fibular development. 4. The shortening of the fibula in infancy causes deformity at the ankle, in the tibia itself and at the knee. 5. At the ankle the poorly developed lateral malleolus causes wedging of the lower tibial epiphysis and valgus at the ankle, which is often unstable. 6. At the knee progressive genu valgum is produced and in the tibia lateral torsion occurs. 7. The clinical significance of these deformities in relation to reconstructive procedures is stressed.
PRIMARY SUBACUTE PYOGENIC OSTEOMYELITIS
Authors: Harris N. H. , Kirkaldy-Willis W. H. 
Published: February 2018

1. A primary subacute type of staphylococcal osteomyelitis has been described. It is the commonest form of osteomyelitis seen in East Africa, and the incidence appears to be increasing in Great Britain. 2. A review of the literature indicates that this is not a new disease but that in the past there has been some confusion in terminology. 3. The causative organism is a coagulase positive staphylococcus, but in a few instances a coagulase negative one has been isolated. The staphylococcus is thought to be of reduced virulence and in East Africa it is likely that the population has acquired an increased resistance to the staphylococcus. 4. Two radiologically distinct groups are recognised, depending on whether a bone abscess is present or not. In the first group there are two types of localised abscesses: the familiar Brodie's lesion and the less well recognised large bone abscess that occurs in the metaphysis of a long bone. While the pathology of the two types is similar, the radiological features are quite distinct. The lesions in the second group are characterised by extensive diaphysial changes, with or without metaphysial involvement, and an obvious abscess cannot usually be demonstrated. 5. The main clinical features are the long history, often weeks or months, before diagnosis; insignificant or absent general reaction to the infection and minimum physical signs. 6. Vertebral body osteomyelitis in adults is included because it generally presents as a subacute infection; the difficulties in distinguishing it from a tuberculous infection are outlined. 7. The most useful diagnostic aids are the staphylococcal antibody titres (especially in vertebral infections) and the erythrocyte sedimentation rate. A limited surgical exposure is usually required if the causative organism is to be isolated and empirical antibiotic therapy is to be avoided. The total and differential white blood count are so often normal in these patients that they are considered to be of no diagnostic value. 8. Curettage and local antibiotics together will cure the localised bone abscess. Other lesions may be effectively treated by systemic antibiotics alone, but in the later stages removal of sequestra and infected granulation tissue may be necessary. In this instance it is essential to make a planned incision and to cut a window in the bone large enough to expose the whole of the lesion; primary suture of the wound is advocated.
METALLIC REPLACEMENT OF THE FEMORAL HEAD
Authors: Martin N. S. 
Published: February 2018

1. After almost seventeen years the three metal prostheses remain in approximately the original position in which they were inserted. 2. All three patients are ambulatory and two of them pleased with the result. 3. The youngest patient, now fifty-six, has a solid ankylosis of the hip and leads an active life free of pain. 4. In view of the attritional changes which have been seen to occur as a result of the reaction of bone to metal, it is suggested that resection replacement operations should be reserved for the primary treatment of certain fractures in the elderly and in those patients who are expected to be mostly inactive for the rest of their life. As a rough guide, it is considered that the operation should not be carried out under the age of seventy.
THE ETIOLOGY AND PREVENTION OF FUNCTIONAL INSTABILITY OF THE FOOT
Authors: Freeman M. A. R. , Dean M. R. E. , Hanham I. W. F. 
Published: February 2018

1. Eighty-five patients have been studied soon after a ligamentous injury at the foot or ankle. These patients were treated in one of three ways, and in fifty-six patients the results were evaluated six to fifteen months after injury. 2. It is concluded: a) that ligamentous injuries at the foot and ankle frequently produce a proprioceptive deficit affecting the muscles of the injured leg; b) that such a deficit is responsible for the symptom of "giving way" of the foot; and c) that the incidence of both the proprioceptive deficit and the symptom of "giving way" can substantially be reduced by treatment after injury with the coordination exercises described in this study. 3. The mechanism of production of the proprioceptive defect is discussed.
DISLOCATION OF THE HIP IN YOUNG RATS PRODUCED EXPERIMENTALLY BY PROLONGED EXTENSION
Authors: Sijbrandij S. 
Published: February 2018

1. Dislocation and subluxation of the hip has been produced in young rats by application of splints reaching from the hip to the foot, bringing the hip into extension. 2. Progressive acetabular dysplasia and anatomical abnormalities of the head and neck of the femur occurred. 3. Results of the experiments suggest that post-natal extension of the hip is of importance in the pathogenesis of congenital dislocation of the hip in man.
INTRACAPSULAR FRACTURES OF THE NECK OF THE FEMUR
Authors: Frangakis E. K. 
Published: February 2018

This study attempts to establish the factors on which the prognosis of an intracapsular fracture of the femoral neck depends, and to draw attention to certain causes of non-union and ischaemic necrosis. These factors are of two kinds: those inherent in the fracture, and those produced by the surgeon. The prognosis depends largely on the nature of the fracture. Original displacement and comminution are the factors which have most influence. Fractures of Type IV with severe comminution have mainly contributed to the bad reputation of intracapsular fractures. Accurate reduction and firm fixation are necessary if the best results for the type of fracture are to be expected. Accurate reduction does not mean merely accurate apposition of the fragments. Fixation of the fracture in certain rotational malpositions such as valgus of over 20 degrees and rotation round the long axis of the neck may occlude the only remaining source of blood supply, the vessels of the ligamentum teres. If these vessels remain open they may produce revascularisation in a femoral head deprived of its blood supply. The degree of valgus can easily be measured but it is impossible to detect rotation round the long axis of the neck. In this analysis only two methods of fixation were studied. It is clear that rigid fixation is of great significance, and a nail-plate, though it may not be the ideal method of fixation, is greatly superior to a Smith-Petersen nail introduced in the usual way. From the results of this survey there is no justification for continuing the use of this method except perhaps in Type II fractures. The greater the risk of non-union the more important is the fixation, and this is true of all fractures. This study also has a bearing on the indications for primary prosthetic replacement. If the nature of the fracture and the result of the reduction make it likely that replacement by a prosthesis is going to be the ultimate solution, and if the patient is over seventy years old, it is wiser to do it as a primary measure. Finally it was shown that condensation and collapse of the femoral head are not the only radiological signs of ischaemic necrosis. An earlier sign is flattening of the weight-bearing area, which appears on an average six and a half months after injury, as compared to condensation, which may not be apparent until eighteen months after injury.
SEVERE CONGENITAL TALIPES EQUINOVARUS
Authors: Attenborough C. G. 
Published: February 2018

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.
BENIGN CHONDROBLASTOMA
Authors: Sundaram T. K. Shanmuga 
Published: February 2018

1. Benign chondroblastoma is a rare primary neoplasm of bone with excellent prognosis. It is believed that instances of it are still being missed. 2. Six cases are described with special emphasis on diagnostic pitfalls. 3. A critical survey of the literature and a discussion on nomenclature and histogenesis are included.
USE OF THE AUSTIN MOORE PROSTHESIS FOR ADVANCED OSTEOARTHRITIS OF THE HIP
Authors: Heywood-Waddington M. B. 
Published: February 2018

1. The early results of thirty Austin Moore arthroplasty operations with acetabular reaming in twenty-five patients with advanced osteoarthritis of the hip have been investigated. 2. The radiological changes after insertion of a prosthesis have been studied. 3. There was a variable degree of improvement in all patients. There was a worth-while improvement in function and relief of pain. Stability, however, was disappointing in more than half (and in all the bilateral cases). An average of three-quarters of an inch of shortening was found in the unilateral cases. 4. In such advanced cases the results of Austin Moore arthroplasty are probably of the same order as for cup arthroplasty, and in many cases they show no more than marginal improvement over pseudarthrosis. 5. It is concluded that at the present stage of progress in the development of arthroplasty the use of the Austin Moore prosthesis with acetabular reaming has very limited indications.
SEPTIC ARTHRITIS OF THE HIP IN ADULTS
Authors: Bulmer J. H. 
Published: February 2018

1. Septic arthritis of the hip in adults is not common and the diagnosis can be difficult. The value of diagnostic aspiration is emphasised. 2. Predisposing causes in fifty patients are analysed and the possible relationship to pelvic infection is discussed. 3. Loss of joint space is occasionally seen within one week of the onset of the infection. 4. A method of treatment is suggested and the value of decompression by arthrotomy is discussed.
TREATMENT OF METACARPAL ENCHONDROMATA
Authors: Giannikas Anastasios C. 
Published: February 2018

1. Three patients with enchondromata of the metacarpal bones are described. 2. The nature of the enchondromata in all three patients was confirmed by histological examination. 3. Treatment was by radical excision and bridging of the gap by a cortical bone graft. 4. There has been no impairment of function in the hands. No patient complained of pain after the operation. 5. Radiographs taken one year after operation in two patients showed that the flat bone grafts had become cylindrical and that medullary canals had appeared.
SALMONELLA OSTEOMYELITIS IN INFANTS
Authors: Ebrahim G. J. , Grech Paul 
Published: February 2018

1. Five cases of Salmonella osteomyelitis in infants without red-cell sickling are reported. 2. All these cases occurred in children under eighteen months of age and within a period of five months of time, suggesting a seasonal incidence. 3. Only one strain of Salmonella was isolated–Salmonella typhimurium. 4. There was complete healing in four of the cases. 5. In one case there was destruction and complete absorption ofthe upper humeral epiphysis.
CONGENITAL MACRODACTYLY
Authors: Ben-Bassat M. , Casper J. , Kaplan I. , Laron Z. 
Published: February 2018

1. A patient with macrodactyly of the middle finger of the left hand was followed up from birth until the finger was amputated at the age of three. 2. The affected finger, besides showing gigantism at birth, grew at a faster rate than the normal fingers. The degree of bone maturation (as judged from the appearance and size of the phalangeal ossification centres) proceeded at a faster rate than the normal fingers. No vascular abnormality which could account for the gigantism was detected either radiologically or microscopically. The affected finger showed histological abnormalities of both bone and soft tissues.
CERVICAL SPONDYLOSIS AND NERVE ROOT LESIONS
Authors: Holt Shirley , Yates Peter O. 
Published: February 2018

1. One hundred and twenty cervical spines removed at routine necropsy from elderly patients dying in a general hospital have been examined. 2. There was some degree of degeneration of intervertebral discs in 110 cases–in forty-six this was severe. 3. Degenerative disc disease was found at an earlier age in men; mild damage preceded severe degeneration and collapse by about a decade. 4. Discs of the lower spine were most frequently and most severely affected. 5. Alterations of the normal cervical lordosis were produced by disc disease in thirty-two cases. 6. Osteoarthritis of the apophysial joints was found in seventy-eight, and by contrast to disc degeneration was commonest in the mid-cervical and upper cervical regions. In eighteen it was severe. 7. Degeneration and scarring of nerve roots was frequently associated with diseased discs; apophysial joint arthritis was found to be an important additional factor when it occurred in the lower cervical region. 8. No nerve root changes could be attributed to ischaemia resulting from narrowing or distortion of the vertebral arteries. 9. Cystic arachnoidal diverticula which excavate the posterior root ganglia were found in thirty-six cases.
BENIGN OSTEOBLASTIC CHANGE RESEMBLING OSTEOID OSTEOMA
Authors: Morton K. S. , Bartletf L. H. 
Published: February 2018

1. Three cases of a benign osteoblastic lesion of bone are described. An outstanding feature of each was the hyperostosis of adjacent bones or synovitis in an adjacent joint. 2. The clinical, radiological and histological features resembled osteoid osteomata more than benign osteoblastoma in each case. 3. The significance of this observation is questioned in relation to the pathogenesis of osteoid osteoma.
VOLKMANN'S ISCHAEMIA IN THE LOWER LIMB
Authors: Seddon H. J. 
Published: February 2018

1. Volkmann's ischaemia of the lower limb is more common in adults than in children and occurs with sufficient frequency after injuries of the femur, knee and leg to warrant a more determined effort to prevent it. 2. The first and most essential step is to recognise the early signs of ischaemic damage. Incision of the deep fascia may then save the threatened underlying muscle, though it may also be necessary to seek for and evacuate a haematoma beneath the muscle. When the femoral or popliteal artery is injured, exploration and repair may be imperative. 3. The treatment of established ischaemic contracture is by whatever measures are necessary to correct the deformity. These are lengthening of shortened tendons, or excision of them if they are involved in dense fibrosis at the periphery of the ischaemic mass; and excision of all totally destroyed muscle. Amputation may be necessary.
THE VULNERABILITY OF THE POSTERIOR INTEROSSEOUS NERVE OF THE FOREARM
Authors: Capener Norman 
Published: February 2018

1. The posterior interosseous nerve of the forearm is vulnerable to constriction in an aponeurotic cleft in the supinator muscle. 2. A case is presented of paresis of the nerve by an intramuscular lipoma which extended into this cleft. 3. A discussion is given of the possible relation of this feature to certain cases of occupational stress–"tennis elbow." 4. An approach is described for decompressing the nerve in the rare cases which do not respond to conservative treatment.
EPIPHYSIAL INFARCTION IN A GROWING LONG BONE
Authors: Young M. H. 
Published: February 2018

1. Experiments are described in which total infarction of the epiphysis was produced in the metatarsal bones of growing rabbits. 2. After operation both proliferation and normal maturation of the cells of the growth plate were slowed or stopped. Cartilage destruction on the metaphysial side of the growth cartilage continued with consequent thinning of the cartilage. Localised areas of cell death appeared in the growth cartilage as early as the second day after operation. These increased in size and led to revascularisation of the epiphysis by metaphysial vessels which grew through the growth cartilage, reaching the epiphysis seven days after operation. The main, central part of the growth cartilage survived intact and its normal structure was restored after epiphysial revascularisation took place. Vessels growing into the bone from outside also contributed to revascularisation of the epiphysis. After revascularisation occurred, new bone formation led to increased radiographic density of the epiphysis.
OCCIPITO-CERVICAL FUSION
Authors: Hamblen D. L. 
Published: February 2018

1. Thirteen cases of occipito-cervical fusion performed in the past fifteen years at the London Hospital are described. 2. Seven of the patients had congenital anomalies in the region of the foramen magnum, six had spontaneous atlanto-axial dislocations, and in one case the operation was performed prophylactically to stabilise a severely disorganised cervical spine. 3. Nine of the patients had evidence of neurological involvement before operation due to pressure on the spinal cord or nerve roots. 4. Operative fusion was successful in all cases and there was no operative mortality. 5. The clinical results were good in eight cases and four patients were improved. The condition of one patient, in whom progressive disseminated sclerosis was also present, deteriorated. 6. The technique of operation is described, and it is recommended that it should always be performed as a combined orthopaedic and neurosurgical procedure.
MADELUNG'S DEFORMITY
Authors: Henry Adrian , Thorburn Marigold J. 
Published: February 2018

1 . A classification of Madelung's deformity on an etiological basis is suggested. 2. Seven patients with "idiopathic" Madelung's deformity and one occurring in association with Turner's syndrome are discussed. 3. Cytogenetic studies of five patients are recorded and their significance discussed. 4. Arthrodesis of the radio-carpal joint by the "wedge" technique is preferred for those patients whose symptoms warrant treatment.
THE DUAL NATURE OF EPIPHYSIAL CARTILAGE
Authors: McKibbin B. , Holdsworth F. W. 
Published: February 2018

1. The hypothesis is put forward that the cartilage of a developing epiphysis consists of two separate moieties. There is a superficial zone which from the first is destined to become articular cartilage and is incapable of ossification, whereas the deeper layers are concerned with the actual growth of the epiphysis and will eventually be converted totally to bone. 2. The results of an experiment which support this theory are described. A piece of developing joint cartilage was excised and replaced in its bed upside down. It was found that although the cartilage continued to proliferate at its normal rate, ossification of the original articular layer did not occur, so that there was a considerable increase in the thickness of the excised cartilage. 3. The supporting evidence for the hypothesis is discussed.
AN EXPERIMENTAL MULTIPLE BARBED SUTURE FOR THE LONG FLEXOR TENDONS OF THE PALM AND FINGERS
Authors: McKenzie A. R. 
Published: February 2018

1. Multiple barbed sutures made from nylon are described and the theoretical advantages with the use of the nylon are outlined. 2. Methods of joining tendon stumps using the multiple barbed sutures are illustrated and in vitro tests show that the anchorage of this suture in cadaveric and canine flexor tendons is of the same order. 3. Preliminary in vivo tests where the flexor digitorum profundus tendon of dogs have been repaired with multiple barbed sutures show that it maintains apposition of the tendon stump as effectively as the Bunnell "buried core" technique using G 40 stainless steel wire. 4. The multiple barbed suture is an experimental suture for certain compact tendons capable of giving a neat and relatively atraumatic junction. It requires further study and development. It does not appear to make tendon repair technically easier, nor does it alter the indications for operation or management.
RADICAL SURGICAL APPROACH TO SPINAL TUBERCULOSIS
Authors: Kohli S. B. 
Published: February 2018

1. The results are recorded of radical excisional surgery for spinal tuberculosis in eighty-five patients. 2. Clinically satisfactory results were obtained in 97 per cent of seventy-one patients followed up. Radiologically the disease was deemed to be cured in 71 per cent of cases. 3. The average period of rest after operation was three and a half months, and the average hospital stay was five and a half months. 4. Total recovery from paraplegia occurred in 84 per cent of patients so affected.
CONGENITAL INDIFFERENCE TO PAIN
Authors: Ingwersen O. S. 
Published: February 2018

1. A case of congenital indifference to pain in a boy aged fifteen years is described. The boy's sister was similarly affected. 2. Clinical features and treatment are described, and the features are compared with those in previously reported cases. 3. Causation is discussed in the light of the negative findings at necropsy on the patient's sister.
ILIACUS HAEMATOMA
Authors: Goodfellow John , Fearn C. B. d'A. , Matthews J. M. 
Published: February 2018

1. Haemorrhage into the fascial compartment which contains the iliacus muscle and the femoral nerve is a common complication of haemophilia. 2. The iliacus haematoma syndrome is described and illustrated from the authors' study of thirty episodes occurring in twenty-four patients. 3. The anatomy of the iliopsoas fascia is described and the mechanism of femoral nerve compression explained. 4. Differential diagnosis, prognosis and treatment are discussed and the necropsy findings in one patient are presented. 5. An instance of iliacus haematoma occurring as a complication of anticoagulant therapy is recorded.
